SONOFF THS01 Temperature and Humidity Sensor

The Sonoff THS01 is a compact temperature and humidity sensor made for real-time, accurate readings. It works with Sonoff TH Elite and TH Origin controllers, helping you automate fans, heaters, humidifiers, and more.

Setup is quick and easy. Just plug the sensor into your controller using the RJ9 4P4C port—no extra wiring or tools needed. Once connected, it sends temperature and humidity data to the Smart Life or eWeLink app.

Thanks to its wired design, you get stable and reliable data. Your smart scenes and automations work exactly when they should. Whether you’re managing a room, greenhouse, server cabinet, or garage, this sensor keeps things running smoothly.

You can automate devices based on real conditions. For example, turn on a fan if it’s too warm, or switch on a dehumidifier when humidity rises. The sensor supports both °C and °F, so you can choose what works best for you.

Its small size and flexible cable let you place it anywhere—behind furniture, in corners, or inside equipment. It’s made for 24/7 use, with strong performance and no overheating.

With the THS01, you get smarter control over your space. It’s a great choice for saving energy and improving comfort without constant manual changes.

Pair it with your Sonoff TH series controllers for smarter, automated climate management.
