It’s cool to make an old-fashioned fan controlled by temperature, isn’t it? When the surface temperature of an object or the temperature in an area is higher than a preset value, your traditional fan will turn on automatically to cool the object or the room. Just with a very cheap Sonoff temperature sensor and a low cost Sonoff smart switch, you can quickly DIY such a smart temperature controlled fan. It can not only be controlled by temperature, but also can be remotely controlled by your phone or table via WiFi.
In this tutorial, I’ll show you how to DIY a smart temperature activated fan with an old-fashioned fan.
