The SI-TH-02 sensor is part of the IQ Home sensor family. These industrial-grade devices are developed to automatically collect measurement data and send it to your preferred data processing platform. The sensors run on Li-Ion batteries, which take a long time to run out.


The SI-TH-02 sensor is a temperature and relative humidity measuring device. This makes it perfect to measure ambient air quality in huge offices and smart buildings. With these, you can easily control HVAC, BMS, IAQ, and the performance of test instruments.


Key features:

  • Low power ISM frequency-based wireless sensor
  • Ready to use, IQRF-DPA compatible device
  • Single 3.6V Li-Ion Battery power supply
  • More than 3 years of battery life*
  • Easy-to-use communication protocol
  • Data collection from devices with one RF command

*Battery life depends on the frequency of the measurement, the sensor's sleep period, RF network size and topology, and operating temperature.
