SI-TH-02 is a battery-powered industrial wireless sensor for temperature and relative humidity monitoring. Its IP65 enclosure makes it suitable for industrial and outdoor installations within the specified operating range. It communicates over IQRF-DPA with IQ Home gateways and compatible third-party systems.
Typical applications include industrial process monitoring, outdoor environmental measurement, building services and remote data collection.
Key features
Temperature measurement range: -40 to +85 °C; typical accuracy ±0.3 °C; resolution 0.0625 °C
868 MHz low-power radio with 8 mW output (916 MHz on special request)
3.6 V, 2400 mAh Li-Ion AA battery included
IP65 wall-mount enclosure, light grey
Internal PCB antenna and internal red/green status LED
Operating and storage temperature: -40 to +85 °C
Integration and installation
The sensor can be integrated into IQRF-DPA networks and read through an IQ Home gateway. Measurement data can then be forwarded to monitoring software, a PLC, a building management system or a cloud platform, depending on the system configuration.
The IP65 housing supports wall mounting in industrial and outdoor locations. Install the sensor so that the measured location and ambient conditions remain within the published measurement range.
