SN-THC-03 is a battery-powered wireless sensor for indoor monitoring of carbon dioxide (CO₂), temperature and relative humidity. It is part of the IQ Home sensor family and communicates over IQRF-DPA with IQ Home gateways and compatible systems.

Typical applications include indoor air-quality monitoring, building automation, HVAC checks and environmental data collection in offices and other indoor spaces.

Key features

• CO₂ measurement range: 0 to 5000 ppm; typical accuracy ±(30 ppm + 3% of reading)
• Temperature range: 0 to +50 °C; typical accuracy ±0.3 °C
• Relative humidity range: 0 to 85% RH; typical accuracy ±3% RH
• IQRF-DPA 3.02 and IQRF-OS 4.02D
• 868 MHz low-power radio with 8 mW output (916 MHz on special request)
• 3.6 V lithium battery supply
• Wall-mountable 80 × 80 × 25 mm IP30 ABS enclosure
• Red/green LED status indication

Integration and installation

The sensor can be read through an IQ Home gateway or another compatible IQRF-DPA network. Depending on the system configuration, data can be forwarded to monitoring software, a building management system, a PLC or a cloud platform.

Install the sensor in a dry indoor location. The IP30 enclosure provides no water protection. Operating temperature: 0 to +50 °C; relative humidity measurement range: 0 to 85% RH.
