Sonoff TH16 is a wireless temperature and humidity monitoring switch which can remotely monitor and set temperature and humidity range to turn on/off connected appliances through the iOS/Android APP eWeLink. Just as the name indicates, the Sonoff TH temperature and humidity monitor device supports two maximum current supply specifications: 10A or 16A.

Sonoff TH16 remote temperature monitor and wireless humidity monitor WiFi switch supports presetting the range for temperature or humidity. When the temperature or humidity of the environment falls within the range, it will automatically turn on or off the connected devices.

Sonoff TH16 supports four kinds of temperature monitor and humidity monitor sensors, mentioned below: Si7021, AM2301, DS18B20, DHT11

Compare with other sensors, Si7021(wiki) is more accurate. It's highly recommended!

With the latest eWeLink app, users can create a series of simple conditional statement (Smart Scene) to trigger on/off other smart devices. This means users can use Sonoff TH16 with Si7021, AM2301, DS18B20 or DHT11 sensor to collect temperature/humidity data, which can be used to as a condition to trigger on/off other devices, such as Sonoff, Sonoff RF, Sonoff SV, S20 smart socket. This device works perfectly with electric fan, air conditioner, humidifier, smart fish tank, watering system, etc.
