TH200
1-Wire Temperature & Humidity Sensor
- ±0.2 °C and ±2 %RH accuracy
- −30 °C to +80 °C operating range
- 1-Wire interface, 1 m cable with ready-to-connect wire ends
TH200 is a 1-Wire temperature and humidity sensor on a 1 m cable. It measures temperature from −30 °C to +80 °C with ±0.2 °C accuracy (5–60 °C) and relative humidity from 0 to 100 % with ±2 %RH accuracy (20–80 %RH). It connects to the 1-Wire interface of Assistant Telematics trackers, so the readings are reported together with the vehicle's or asset's location.
