TH16 DIY 16A 3500W Smart Home WiFi Wireless Temperature Humidity Thermostat Module APP Remote Control Switch Socket with DS18B20 Waterproof Temperature Probe

TH16 DIY 16A 3500W Smart Home WiFi Wireless

Overview:Sonoff TH16 is a Sonoff version that can monitor and set temperature and humidity through the APP eWeLink. Just as the name indicated, the new version Sonoff TH device supports two power supply specifications-16A. It supports preset a temperature and humidity range, when the temperature and humidity of the environment falls into the range, it will automatically turn on or turn off connected devices.The device supports connecting to three kinds of temperature and humidity sensors (AM2301, DS18B20, Si7021). Actually, Sonoff TH16 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, Si7021) 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.Featu...
