6PCS Temperature Controller Module XH-W1209 LCD Display Digital Thermostat Module with Waterproof NTC Probe -50~110℃ DC 12V Electronic Temp Control Module Switch

An incredibly low cost, but 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 current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an on board LED.
