Overviewonoff TH10/16 is a Sonoff version that canmonitor and set temperature and humidity throughthe APP eWeLink. Just as the name indicats, thenew version Sonoff TH device supports two powersupply specifications: 10A or 16A. Sonoff TH 10/16supports presetting range for temperature orhumidity, when the temperature or humidity of theenvironment falls into the range, it willautomatically turn on or turn off connecteddevices.The device supports connecting to three kinds of temperature and humidity sensors(AM2301, DS18B20, DHT11). Actually, Sonoff TH 10A/16A Sonoff TH 10A/16A can workas a Sonoff when without connecting to a sensor. But compared to Sonoff, Sonoff10/16 is more safer, less radiation and in bigger size, easy operation. Mostimportantly, with the support of latest ewelink app, you can create chains of simpleconditional statements(Smart Scene). This means you can use them with temperatureand humidity sensors (AM2301, DS18B20, DHT11) to collect temperature and humiditydata, while these data can be used to trigger ON/OFF other smart devices(Sonoff,Sonoff RF, Sonoff SV, Slampher, smart socket, etc.) under your account. This deviceis perfect to work with electric fan, air conditioner, humidifier. Please note thatthis version does not have 433MHz RF function.We are selling two kinds of sensors: AM2301 and DS18B20. We've customize aninterface for Sonoff TH10/TH16 to easily connect with the sensor, just plug and play.Note that the sensor should be plug into Sonoff TH before you power it up, don'tplug or unplug the sensor in power on status. AM2301 is non-waterproff, while DS18B20can work in water.
