Sonoff - No Battery ZigBee Temperature & Humidity Sensor

Measure the temperature and humidity in real time, and sync data to your mobile phone in no time. Wish your home always keeps a favourable temperature and humidity? Enable the smart scene to make the fan automatically turn on when the room temperature reaches 28C and the humidifier automatically turns on when the room humidity is below 45%RH. Adopts 3M adhesives on the bottom of the sensor for flexible and fast installation on any surface of your home. You will get a notification of low-battery level when the battery life gets 10% remaining. Simply share the sensor to your family and they can directly check this temperature and humidity on their mobile phones without pairing it.
