The AM2301 sensor monitors real-time temperature and humidity for your home or outdoor spaces. Its customized plug supports to work with SONOFF TH. The WiFi temperature sensor can wirelessly transmit temperature data through iOS / Android APP "eWeLink" to mobile.
AM2301 capacitive humidity sensing digital temperature and humidity module is the one that contains the compound that has been calibrated the digital signal output of the temperature and humidity sensor. 
The sensor should be plugged into the smart switch before power-on. It is not advised to plug or unplug the sensor after power-on.

With the eWeLink app, users can create simple conditional statements (Smart Scene) to trigger on/off other smart devices.  This means users can use Sonoff TH10 or Sonoff TH16 with Si7021, AM2301, DS18B20 or DHT11 sensor to detect temperature/humidity, and then set specified temp. or hum. ranges as conditions to trigger on/off other smart devices in the same account, such as Sonoff Basic, Sonoff RF, Sonoff SV, S20. This device works perfectly with electric fan, air conditioner, humidifier, smart fish tank, watering system, etc.
This is an Ultra-low-power, fully automated calibration that uses the capacitive humidity sensor and completely interchangeable. It includes standard digital single-bus output with excellent long-term stability.
AM2301 sensor is suitable for Sonoff TH10/TH16 Temperature And Humidity Monitoring WiFi Smart Switch.
