SONOFF THS01 - Temperature and humidity sensor, Black

The SONOFF THS01 Wired Temperature and Humidity Sensor is a wired digital sensor for indoor climate monitoring. It measures temperatures from –40 °C to 85 °C, including readings below freezing and at elevated temperatures. Relative humidity measurement spans 0% to 100%, covering the full stated humidity range. Temperature accuracy is specified as 0.5 °C. The sensor is intended for indoor use, where its readings can support climate monitoring, smart-home automation and appliance control.

An RJ-11 interface connects the sensor to compatible SONOFF TH Elite and TH Origin devices. It draws power from the connected device, so it does not require a separate battery. Installation is plug and play, with the sensor connected through a compatible host rather than operating as a standalone wireless unit. As a wired sensor, its placement depends on the cable route to the host. The optional SONOFF RL560 extension cable is compatible when the sensor needs to be positioned farther from the connected switch.
