1. Introduction
The ZMOD44xx Gas Sensor Family is highly configurable in order to meet various application needs. This document describes a general
program flow to set up ZMOD44xx gas sensor modules for gas measurements. The term ZMOD44xx refers to any product in the ZMOD44xx
Gas Sensor Family such as the ZMOD4410 Gas Sensor Module for TVOC and Indoor Air Quality. In addition, this document describes the
function of an example code provided as a C file by IDT for the ZMOD4410, which can be operated using its evaluation kit (EVK). The
ZMOD4410 is designed for the detection of total volatile organic compounds (TVOC) and provides an output for an estimated carbon dioxide
level (eCO2) and a rating for the indoor air quality (IAQ).
Recommendation: Read the datasheet for the specific ZMOD44xx product before using this manual.
2. Hardware Setup for the ZMOD4410
To implement the ZMOD44xx sensor with the user’s program, specific hardware is needed. The example below shows the ZMOD4410 EVK,
which consist of three components:
ZMOD44xx HiCom Communication Board
ZMOD4410 Sensor Board (Daughter Board) with the ZMOD4410 Gas Sensor Module
Micro-USB cable
Refer to the ZMOD4410 Evaluation Kit Description for instructions on assembly, connections, and installation of hardware and software.
Figure 1 shows the assembled evaluation kit.

3. General Program Flow for Setting up ZMOD44xx Gas Measurements
To operate the ZMOD44xx in the hardware and use its full functionality, four code blocks are needed as illustrated in Figure 2:
The “Target Specific I2C and Low-Level Functions” block is the hardware-specific implementation of the I2C interface, it contains read and
write functions to communicate with the ZMOD44xx. If the IDT EVK is used, files for the Hi Com Communication Board are provided with
this manual. Custom microcontrollers can be used to establish I2C communication.
The “Application Programming Interface (API)” block contains the functions needed to work with the ZMOD44xx. A detailed description of
the API can be found in the document: ZMOD44xx_API.pdf.
The “Programming Example” block provides a code example that is used to initialize the ZMOD4410 gas sensor module, operate it at a
constant temperature of 300°C, and display the data for TVOC, IAQ, and eCO2. Further details can be found in section 4 of this
document.
The “Libraries” block contains the functions and data structures needed to calculate eCO2, IAQ, and TVOC. The libraries are described in
more detail in the document ZMOD44xx_gas_lib.pdf.
To avoid naming conflicts, all function names start with the prefix “zmod44xx_” in the ZMOD44xx code. This naming applies to all products
in the ZMOD44xx product family.

4. Description of the Programming Example Code
The following section describes the example code and how to use the ZMOD4410 Gas Sensor Module. In the example, the ZMOD4410 is
initialized and configured for continuous operation at 300°C, and then it displays measured values. The example is intended to work on a
Windows® (trademark of Microsoft, Inc.) computer in combination with the IDT gas sensor EVK. However, the example can be adjusted to
operate on other platforms such as ARM® (trademark of ARM, Ltd.) and Linux® (trademark of Linus Torvalds).
To run the example using the EVK without further configuration, run ZMOD44xx_example.exe, which is included in the kit software.
4.1 main Files
The main.c / main.h files contain the main program flow.
The TVOC, IAQ, and eCO2 algorithm is configured by setting the parameters according to the TVOC (IAQ, eCO2) library. Then the target
specific initializations are performed. The ZMOD4410 is configured by reading the Final Module Test parameters from the sensor’s nonvolatile
memory (NVM) and initializing it to run continuously at 300 °C.
An endless loop continuously checks the status of the ZMOD4410 and reads its data. The raw data is subsequently processed, and the TVOC,
IAQ, and eCO2 values are calculated. All values are shown in a command line window. To stop the loop, press any key, which releases the
hardware and stops the program.

4.2 Program Flow to Run the Sensor
Refer to the example code for more details.
Table 1. Program Flow
Note: In the following table, lines that are shaded blue can be run in an endless loop with polling or interrupt usage.

Reset the sensor.
Before configuring the sensor, it is necessary to reset
the sensor by powering it off/on or toggling the reset
pin.

nonvolatile memory (NVM).
This step is necessary to choose the correct
configuration for the sensor.

5. Using the Example on a Different Hardware Platform
To incorporate this programming example into a different hardware platform, it is necessary to set the device’s struct pointers read, write and
delay_ms. The type definitions of the function pointers can be found in zmod44xx_types.h (see Figure 2). The functions read and write should
point to the I2C implementation of the hardware used.
In addition, IDT provides precompiled algorithm libraries that are hardware-platform dependent. IDT offers a download of these libraries for
x86/x64 (Linux/Windows) as well as for ARM and MSP microcontrollers.
5.1 Adaptation for the Target System
IDT’s ZMOD44xx C API is located between the application and the target hardware.

Low-level Hardware Functions
Target Hardware
The low-level I2C functions are implemented in the file hicom_i2c.c (see Figure 2) for the EVK hardware running on a Windows-based computer
and the HiCom Communication Board.
5.2 Error Codes
Most of the API functions return a code to indicate the success of the operation. If no error occurred, the return code is 0. In the event of an
error, a number not equal to zero is returned. The API has predefined symbols ZMOD44XX_ERROR_* for the error codes defined in
zmod44xx_types.h.
