1Product Description
1.1 Overview
The Smart Room Sensor is a multi-purpose LoRaWAN IoT sensor packed into a very small form
factor. The Smart Room Sensor is ideal for monitoring and reporting temperature, humidity,
light, barometric pressure, motion, and CO2levels in an indoor environment. Table 1-1 presents
the available Smart Room Sensor models and corresponding LoRa channel plan [1]. Table 1-2
presents the features available in the three functional variants (CO2, PIR, and CO2 & PIR).

1.2.1 Transducer Details
1.2.2 Temperature/Humidity Sensor
The Room Sensor includes a combination temperature/humidity transducer from Sensirion
(SHTC3). It is a small footprint, very low power device. It features operation over I2C protocol
and operates from 0% to 100% RH and -40°C to 125°C with a typical accuracy of ±2% RH and
±0.2°C. The typical and maximum accuracies specified across the operating relative humidity
and temperature range of the sensor are shown in Figure 1-2 and Figure 1-3, respectively.

The sensor provides light intensity measurements, but they are not calibrated in lux. See the Technical Reference
Manual Invalid source specified. for more details.
3
No data available from manufacturer on performance outside the range of 15°C to 35°C and 0% to 80% RH.

1.2.3 Ambient Light Sensor
A phototransistor and bias resistor form a light detection transducer on the Room Sensor. The
light sensor provides a sufficient window of detection to allow detection of desired light levels.
This window will be tuned as necessary by changing the resistor to give a detection window

Smart Room Sensor (Gen4) User Guide T0007525_UG Version 1.0
TEKTELIC Communications Inc. Page 10 of 18
corresponding to the light levels to be detected. The output of the light transducer is an analog
voltage that is read by the MCU ADC.
Vishay’s TEMT6200FX1 is a phototransistor specifically designed for ambient light sensing as it
includes a filter to give a response similar to the human eye, thus being capable of detecting
weak light to typical work light conditions.
1.2.4 Barometer
A barometer is included in the Room Sensor in order to measure the barometric air pressure.
Infineon’s DPS310 is designed for low power applications while provided highly accurate
measurements. The sensor can operate over a range of 300 hPa to 1200 hPa, and can
communicate over I2C or SPI protocols. The pressure accuracy of the sensor is ±1 hPa between
300 hPa and 1200 hPa while operating between 0°C and 65°C.
1.2.5 CO2Concentration Sensor
The Room Sensor includes the Senseair Sunrise to measure the CO2concentration using non-
dispersive infrared (NDIR). It operates over an I2C interface and can measure in the range of 400
ppm to 5000 ppm with an accuracy of up to ±30 ppm +3% of the reading. This sensor also
features an extended range of up to 10000 ppm with a projected accuracy of extended range
±10% of the reading.
1.2.6 PIR Sensor
A motion detection feature on the Room Sensor is implemented with a PIR sensor. Panasonic’s
EKM1291111 is specifically designed to be sensitive enough to detect small movements with a
wide field of view of 104° x 104°.
The motion detection system uses a ceiling mount type lens that has an expected coverage area
of 7.7 m x 7.7 m when ceiling mounted at a height of 3 m. Note that this is the theoretical
maximum sense range claimed by the transducer manufacturer. The sense range is determined
as the projection of the transducer FoV on the ground, and therefore, should not be interpreted
as the coverage area where the sensor can detect moving people. In general, due to the conical
nature of the transducer FoV, people need to be closer to the sensor to be detected. The
amount of IR radiation from a moving person, which is also impacted by the person’s clothing
or type of skin cover, also plays an important role at determining the detection range.

2Installation
2.1 Included Product and Installation Material
The following items are included with each sensor:
•Smart Room Sensor
•Mounting Bracket
•User Guide
2.2 Safety Precautions
The following safety precautions should be observed:
•The Smart Room Sensor is intended for indoor use only.
•The Smart Room Sensor contains lithium batteries.
•NEVER allow small children near batteries: if a battery is swallowed, immediately seek
medical attention.
•To reduce risk of fire, explosion or chemical burns: replace only with approved 2xAA LTC
batteries; DO NOT recharge, disassemble, heat above 100°C (212°F) or incinerate battery.
2.3 Unpacking and Inspection
The following should be considered during the unpacking of a new Smart Room Sensor:
1. Inspect the shipping carton and report any significant damage to TEKTELIC.
2. Unpacking should be conducted in a clean and dry location.
3. Do not discard the shipping box or inserts as they will be required if a unit is returned for
repair or re-configuration.
2.4 Required Equipment for Installation
There are no tools required for Smart Room Sensor installation.
2.5 Smart Room Sensor Mounting
Smart Room Sensor is designed to be mounted using the supplied mounting bracket. The
bracket can be attached using screws or double-sided tape (not included).
When mounting on a vertical surface, ensure that the Room Sensor will not be orientated with
the case retaining screws towards the ceiling. This could cause the Room Sensor to accidently

Smart Room Sensor (Gen4) User Guide T0007525_UG Version 1.0
TEKTELIC Communications Inc. Page 12 of 18
slip off the mount and fall. There are no orientation concerns when the Room Sensor is
mounted to a horizontal surface.

3Power UP and Commissioning, and Monitoring
3.1 Required Equipment
No special equipment is required to power on the Smart Room Sensor.
3.2 Power Up/Down Procedure
Once the sensor information has been added to the Network Server, pull out the battery tabs
to engage the battery. To turn off the device the batteries must be removed, but to simply
reset the device, the external reset button can be pushed; see Section 4.4 for description of the
reset function.

4Operation, Alarms, and Management
4.1 Configuration
The Smart Room Sensor supports a full range of Over-the-Air (OTA) configuration options.
Specific technical details are available in the Room Sensor Technical Reference Manual [2]. All
configuration commands need to be sent OTA during a sensor’s downlink windows.
4.2 Default Configuration
The default configuration on the Smart Room Sensor is:
•Report Temperature and Humidity every one (1) hour.
•CO2 model only:
oReport the carbon dioxide (CO2) concentration every 15 (fifteen) minutes.
•PIR model only:
oReport motion after 1 (one) PIR event.
oClear motion after 5 (five) minutes of no motion.
•CO2 & PIR model only:
oReport the carbon dioxide (CO2) concentration every 15 (fifteen) minutes.
oReport motion after 1 (one) PIR event.
oClear motion after 5 (five) minutes of no motion.
4.3 LED Behaviour
During the join procedure:
•After the Sensor has gone through the initial boot procedure, the join procedure will
begin. During that time, the red LED will blink continuously until the sensor has joined a
network.
During normal operation:
•The green LED will blink when the Sensor transmits a packet.
•The red LED will blink when the Sensor receives a packet.

4.4 Reset Button Function
There is a reset button on the device, that can be pushed by a pin, such as a paper clip. The
button should not be pushed hard. The reset is instant, i.e. the button does not need to be kept
pushed. The reset restarts the microprocessor. All the FW load and configuration parameters in
the Flash are remembered during the reset.
