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 temperature sensor.
Although this module has an embedded micro controller 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.
