1 Product 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 CO2 levels 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 Specifications The Smart Room Sensor specifications are listed in Table 1-3.
Light sensitivity Pressure measurement accuracy CO2 concentration measurement accuracy Motion detection Detection of weak light to typical work light conditions (5 lux to 1000 lux)2 Peak sensitivity at 550 nm < ±1 hPa between 300 hPA and 1200 hPa ±30 ppm +3% of reading between 400 ppm and 5000 ppm Extended range ±10% of reading for an extended range of up to 10000 ppm3 Pyroelectric infrared sensor Ceiling mount: • X-angle: 104° (no mask) • Y-angle: 104° (no mask) Height: 3 m (no mask) 1.2.

The light sensor provides a sufficient window of detection to allow detection of desired light levels.
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.
2 Installation 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.
slip off the mount and fall. There are no orientation concerns when the Room Sensor is mounted to a horizontal surface. Smart Room Sensor (Gen4) User Guide TEKTELIC Communications Inc. T0007525_UG Version 1.
3 Power 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.
4 Operation, 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.
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. Smart Room Sensor (Gen4) User Guide TEKTELIC Communications Inc. T0007525_UG Version 1.
