How to setup a DHT11 with your Raspberry Pi

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 work as a Sonoff when without connecting to sensors. But compared to Sonoff, Sonoff 10/16 is more safer, less radiation and in bigger size, easy operation. Most importantly, with the support of latest ewelink app, you can create chains of simple conditional statements(Smart Scene). This means you can use the them with temperature and humidity sensors (AM2301, DS18B20, DHT11) to collect data, while these data can be shared to other ITEAD smart home devices(Sonoff, Sonoff RF, Sonoff SV, Slampher, smart socket, etc.) under your account, thus other devices can use the data to control connected appliances. This device is perfect to work with electric fan, air conditioner, humidifier. Please note that this version does not have 433 RF function.
