Zigbee Temperature & Humidity Sensor -40 °C

Complete your smart environment – whether it's indoors or in extreme temperature zones like refrigerators and freezers. This versatile Zigbee sensor measures temperatures down to -40 °C* and humidity up to 99% RH, and works seamlessly with the Telldus app.

Perfect for everything from the living room, conservatory, and greenhouse to cold storage, the cold room, or winter storage for your caravan – all places where traditional sensors fall short.

Installation is simple: insert the battery, hold down the button for five seconds, and pair it with the Telldus hub 1 via the app. After that, the sensor automatically reports measurements every 30 minutes and can be used to trigger other smart devices – such as starting a fan heater, turning on a dehumidifier, or sending push notifications in case of frost or humidity risk.

The sensor has ultra-low power consumption for long battery life. A robust and reliable solution for all your temperature and humidity monitoring needs.

*For temperatures below -20 °C, a lithium battery (CR2032) designed for low temperatures (at least -30 °C operating temperature) is required. Standard batteries may limit functionality at very low temperatures.
