SI-TH-02/SC is a battery-powered industrial wireless sensor for temperature and relative humidity, supplied with a 1.5 m external sensor cable. The separate probe allows measurements at a point away from the IP65 transmitter housing, while data is transmitted over IQRF-DPA.

Key features

• Temperature measurement range: -40 to +85 °C; typical accuracy ±0.3 °C; resolution 0.0625 °C
• Relative humidity measurement range: 0 to 100% RH; typical accuracy ±2% RH; resolution 0.0625%
• 1.5 m sensor cable
• IQRF-DPA 4.11 and IQRF-OS 4.03D
• 868 MHz low-power radio with 8 mW output (916 MHz on special request)
• 3.6 V, 2400 mAh lithium AA battery included
• IP65 wall-mount transmitter housing, light grey
• Internal PCB antenna and red/green status LED

Installation and integration

Mount the transmitter on a wall or suitable surface and route the 1.5 m sensor cable to the measurement point. Protect the cable and probe from mechanical damage and conditions outside their rated range.

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