Description
The ZMOD4410 Evaluation Kit (EVK) is designed for evaluating
IDT’s ZMOD4410 Gas Sensor Module for TVOC. The total volatile
organic compounds (TVOC) measurement is one of the indicators
for indoor air quality (IAQ). In addition, a measurement mode is
provided to trigger an external device (e.g., fan, ventilation) based
on the air quality change.
The ZMOD4410 Evaluation Software allows Windows®-based
operating systems to communicate with the ZMOD4410 EVK via a
USB connection on the user’s computer, which functions as a
master. The software and additional related documentation is
available on the IDT website.
The EVK’s Communication Board (HiCom) handles the interface
between the user’s computer and the ZMOD4410 module mounted
on the ZMOD4410 Sensor Board (Daughter Board). Note: Only one
Communication Board with one Sensor Board can be connected to
the computer at a time.
The ZMOD4410 Evaluation Kit uses an FTDI controller on the
Communication Board to handle the USB protocol, translate
communications, and synchronize communications with the I2C
interface. The Sensor Board includes a decoupling capacitor.
The Communication Board has devices mounted on both sides.
The components on the top side generate a stable supply voltage.
A potentiometer can be used to adjust the internal supply voltage
in the typical range from 1.7V to 3.6V. Alternatively, the user’s
external supply voltage can be used. The intensity of the adjacent
LED is proportional to the supply voltage.

1. Setup
1.1 First Startup
To set-up and operate the ZMOD4410 Evaluation Kit (EVK) with the ZMOD4410, refer to the ZMOD4410 EVK Quick Start Guide document
included in the kit.
1.2 Required or Recommended User Equipment
By default, the internal supply voltage for powering the Sensor Board is generated from the USB voltage supplied by the user’s computer via
the USB cable. If there is a need for currents higher than the defined USB Standard (usually 500mA at 5V), an external voltage supply source
can be used instead of the internally generated voltage supply provided on the Communication Board. For details, see section 0.
The external supply powers only the sensor modules, and not the communication board itself. The supply must meet the following requirements:
Voltage. 1.7V to 3.6V
Current must meet the user’s specifications. The minimum is 30mA for electrics with additional need for each gas sensor module of
approximately 13mA (at 1.8V voltage supply).
1.3 User Computer Requirements
1.3.1 Computer Requirements
A Windows®-based computer is required for interfacing with the EVK and configuring the ZMOD4410. The user must have administrative rights
on the computer to download and install the ZMOD4410 Evaluation Software.
The computer must meet the following requirements:
1GB RAM
Hard drive with at least 500MB free space
1 USB port
Windows Vista/Windows 7/Windows 8/Windows 10
Internet access for initial download of the drivers and software
Important: Before installing and activating the software, assemble and connect the hardware for the kit to the user’s computer according to
steps 1 through 3 in section 0.
1.4 Software Installation and Setup
Before using the ZMOD4410 Evaluation Software, the USB drivers for the FTDI device must be installed. Download the drivers and
corresponding installation guides from the FTDI website (www.ftdichip.com). The drivers will not affect the operation of any other USB
peripherals. The kit does not need to be connected during installation of the drivers.
Follow these procedures to download and install the ZMOD4410 Evaluation Software with the kit connected:
1. Download the ZMOD4410 Evaluation Software zip file at www.IDT.com/ZMOD4410-EVK.
2. Create a folder on the user’s computer for the software (e.g., C:\Program Files (x86)\IDT Software). Extract the contents of the
downloaded zip file into this folder.
3. Double-click on the extracted batch file ZMOD4410_Evaluation_Software.bat to start the software. There is no need for an installation of
this software for user convenience. Figure 1 shows an example of the initial display after execution.
4. Select the measurement mode to run the sensor in “Standard Operation” or “Low Power Operation”to either measure IAQ/TVOC/eCO2,
or alternatively choose the “Odor” option to trigger the activation of an external device by changes in the air quality.

1.5 EVK Hardware Connections and Initial Power-up
To set up the EVK hardware before using the software, complete the following procedure:
1. Refer to Figure 2, Figure 3, and Table 1 to determine the correct jumper settings for the ZMOD4410 Communication Board depending on
whether an external supply or the internal voltage supply on the board is used.
If the internal voltage supply is used, ensure that the jumper is across the pins labeled “int” on the K2 connector.
If using an external supply, ensure that the jumper is across the pins labeled “ext” on the K2 connector. In this case, without
connecting the external supply to the Communication Board, verify that the external voltage supply setting does not exceed the
voltage supply specifications -- a minimum of 1.7V or a maximum of 3.6V -- as per the ZMOD4410 Datasheet. With the external
supply off, connect the external voltage to the 2-pin “+ - V ext” header adjacent to the K2 jumper with the orientation indicated in
Figure 3. Note: If this option is used adjustments of the external voltage are not possible on either the Communication Board, or the
Sensor Board for adjusting an external voltage supply.
2. Install the ZMOD4410 Sensor Board on the 14-pin connector on the ZMOD4410 Communication Board taking care to ensure the proper
orientation of the Sensor Board as shown on page 1.
3. Insert the micro-USB cable into the X1 connector on the Communication Board and connect it to a free USB port on the user’s computer.
If the external voltage supply has been selected, turn on the external supply and verify that the D3 LED adjacent to the potentiometer
is on. See Figure 2. Note: The intensity of the green D3 LED is proportional to the supply voltage.
4. Activate the software as described in section 1.4.
5. If the internal voltage is used, the ZMOD4410 Evaluation Software activates the internal voltage after the sensor has been started. Use
the metal potentiometer to the left of the K2 connector to adjust the VDD supply voltage in the typical range from 1.7V to 3.6V as
measured across the V_TGT and GND pins available on the K3 connector as shown in Figure 3. Its initial adjustment on delivery
provides a voltage of VDD ≈2.0V. Once a measurement has been started by the software, the green D3 LED adjacent to K2 will light
with an intensity proportional to the voltage supply that was set using the potentiometer.
6. Verify that the red D1 LED is on, which indicates that the kit is properly connected and powered.
The Communication Board provides the additional K3 and Modul1 connectors for the following optional uses as described in Table 1. To
make use of any of these options, contact IDT for further instructions (see contact information on last page).
Extra measurement options (e.g., current consumption to determine the power requirements of the ZMOD4410)
Connections for additional sensors (e.g., IDT humidity sensor HS3001)

2. Usage Guide
For all Measurement options, the ZMOD4410 Evaluation Software has two different tabs:
“Measurement”(section 2.1.1)
“Analysis”(section 2.1.2)
To select a tab, clicking on the name in the main screen. When the ZMOD4410 Evaluation Software is executed and the operation mode has
been selected, it shows the “Measurement”tab by default (see Figure 4).
Figure 4. Initial Display for ZMOD4410 Standard Operation Mode and Low Power Operation Mode
On the “Measurement” tab, the user can control the properties of the ZMOD4410’s gas measurements. When the “start sensor” button is clicked,
the measurement starts running continuously with the given sample time (2 seconds fixed for Standard Operation, 5 seconds (default) for Odor
Operation, and 6 seconds fixed for Low Power Operation). IDT sets 300°C as the default temperature.
On the “Analysis” tab, the measurements will be displayed and are processed by different algorithms to calculate the indoor air quality (IAQ)
and equivalent carbon dioxide (eCO2), or the algorithm output to control an external device. The algorithm takes the first 15 measurements for
stabilization. Other features such as TVOC concentration measurement, temperature measurement, and others are also possible. For further
instructions, contact IDT.
The different software tabs, buttons, and entry fields are described in the following sections.

2.1 Software Modes
2.1.1 “Measurement”Tab
Click on the “Measurement” tab to display the measurement options. On this tab, the user can see the properties of the ZMOD4410’s gas
measurements, which includes setting the temperature in °C and changing the sample time in seconds used during the gas measurements.
The sampling rate in Standard Operation is fixed at 2 seconds, while in Low Power Operation it is fixed to 6 seconds. In Odor Operation, the
sample rate can be changed between 1 and 15 seconds.
When the “start sensor” button is clicked, the measurement starts running continuously with the interval selected under “Sample time” via the
up/down arrows. The results will be automatically added to the plots in the “Analysis” tab and continuously saved in a comma separated file
(CSV), which is user-selected via the file selection dialog accessed by clicking the “…” button adjacent to the “Append to data file” field, which
displays the selected path and file name.
A comment (for example, “Apply test gas”) can be added to the data entry by adding a string to the “Add comment to next measurement” field
and then clicking the “ok”button. If a measurement is already in progress, the comment will be added to the next measurement. If a comment
is on hold waiting for the next measurement, it can be deleted by clicking the “clr” button. The comments will be displayed in the plot shown on
the “Analysis” tab and will be saved in the CSV result file. This facilitates tracking the user’s experimental investigations.
2.1.2 “Analysis” Tab
Depending in the operation mode (“Standard”, “Low Power”, or “Odor”) the user will see slightly different screen.
For Standard Operation and Low Power Operation
Click on the tab to display the “Analysis”tab (see Figure 5). The “Analysis” tab shows three plots:
IAQ rating according to the standards of the German Federal Environmental Agency (UBA).
eCO2concentration (in ppm)
Raw sensor signal (in Ω)
For more information on IAQ and eCO2, refer to the ZMOD4410 White Paper –Overview of TVOC and Indoor Air Quality and the ZMOD4410
Application Note –Estimating Carbon Dioxide.
There are four sections for user interaction located above the graphs:
Data source

Figure 6. “Analysis” Tab for Measurement Mode “Odor”
The available user options are described in Table 2 for all measurement modes.
The “Analysis” tab can be used to see the active measurement data and to load previously acquired measurement result files by using the “load
data file” button. For this usage, it is not necessary to connect the ZMOD4410 Evaluation Kit hardware. The “Analysis” tab supports data files
with data from multiple sensors if the loaded CSV file has the required format. One sensor will be processed and displayed at a time.
For Standard Operation and Low Power Operation, the default algorithms applied in the “Analysis” tab calculate gas concentrations for eCO2
and IAQ. Other algorithm results –e.g., calculations of concentrations of ethanol and total volatile organic compounds (TVOC) –are available
upon request.
The algorithm results will be displayed as a colored bar in the “Algorithm Result” section above the graphs (see Table 2) and in the “Algorithm
Result” plots. The first 15 measurements after the start of a measurement are taken for initialization process. To export the data from the
“Analysis” tab into a separate measurement file (CSV), click the “export data” button. Note that only the data shown in the recent plots will be
exported.

Table 2. Analysis Tab User Options
Display Section
Button/Action
Description
“Data source”
The “clear memory” button will delete all current data from the plots (memory). The data in
the measurement file will remain.
The “load data file” button will open a file selection dialog. This function can be used to
display and analyze data from a measurement file acquired earlier. The data file must have
the same structure as the measurement file created by the ZMOD4410 Evaluation Software.
The “append incoming sensor data” checkbox activates the functionality to append the
current measurement data to the plots in the “Analysis” tab.
If measurements are acquired simultaneously for multiple ZMOD4410 gas sensors, the
measurement results file can contain data from different sensors. In the “Sensor” drop-down
menu, the user can choose a sensor to display by selecting the unique sensor identification
number.
Initial Stabilization
The first measurements of the algorithm will be taken for sensor stabilization. The “Algorithm
Result” field will indicate how many measurements have been completed during this period.
Raw sensor signals are shown on the “Sensor Signal (Ohms)” plot during this time, but the
algorithm results are only calculated after stabilization. Note that this does not cover the full
stabilization of the sensor module but rather covers only the first minutes during startup.
Recommendation: IDT recommends a sample time of 2 seconds for these 15 measurements
resulting in 30 seconds for the initialization measurements.
Algorithm Result for
“Standard Operation”
and
“Low Power Operation”
After the stabilization measurements, the “Algorithm Result” field shows a colored bar
representing the results from the algorithm. The IAQ rating from the Federal German
Environmental Agency (UBA) and the corresponding IDT IAQ rating are shown.
IDT’s patented smart algorithm will provide eCO2 readings with high accuracy when
activated (default). However, for demonstration reasons it might be useful to disable the
eCO2 algorithm to see very fast CO2 changes directly related to the VOC level.
Algorithm Result
“Odor Operation”
After the stabilization measurements, the “Algorithm Result” field shows a colored bar
representing the results from the algorithm. The Air Quality Change is shown in three
categories:
< 10% Minor changes or improvement in Air Quality: Control Signal Off
10% to 30% Slight change in Air Quality: Control Signal Off
> 30% Major change in Air Quality: Control Signal On
The threshold is set to 1.3 (default value). This means only a 30% Signal Change will lead to
set the Control Signal to On status.
After the Air Quality has improved the control signal will remain On for 24 samples (2
minutes for default operation) to avoid a hysteresis. This Control Signal triggers the AD5
GPIO pin on the HiCom board and its status is shown in the on/off field.
“Misc”
The drop-down menu adjacent to the “show” button provides options for selecting the time
period for showing the recent history or the complete data. Click the “show” button to apply
new settings to the plots.
The “export data” button will open a file selection dialog for selecting a path to immediately
save the measurement results and the processed algorithm results of the “Analysis” tab. The
file will be saved in comma-separated format (CSV).
