Description: 

How easy would it be to switch on your fan automatically as and when the temperature increases or decreases? All you need to do is, set a trigger temperature at which the fan should switch on or off. Using W1209 module, which is highly functional and low cost can help you to invent such minor yet amazing automation in your home!

The W1209 is an incredibly low cost yet highly functional thermostat controller. With this module you can intelligently control power to most types of electrical device based on the temperature sensed by the included high accuracy NTC temperature sensor. Although this module has an embedded microcontroller no programming knowledge is required. 3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The on board relay can switch up to a maximum of 240V AC at 5A or 14V DC at 10A. The current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an on board LED.
