XH-W1209 Digital Temperature Sensor and Controller Module
XH-W1209 overview
Temperature Controller Thermostat W1209 Sensor Module has a temperature sensor, keys, LED display, and relay and requires a DC 12V power supply. Temperature Controller Thermostat W1209 is an affordable, good-quality thermostat controller. Thermostats are devices that sense the temperature of a system so that the temperature is maintained at the desired set point or near to it. Temperature Controller Thermostat W1209 is a high-precision temperature control module, it can not only show the temperature, but also according to the current temperature of the relay control, it can control some of the power equipment through the relay, industrial and DIY it is used widely, it comes with a temperature sensor, three buttons for temperature setting and some other functional operation, three digital temperature display, and comes with a program update interface can be used to update.
NTC temperature sensor allows the module to intelligently control varied electrical devices based on the temperature. NTC thermistor has a negative temperature coefficient, which means the resistance decreases with increasing temperature. Temperature Controller Thermostat W1209 has an inbuilt embedded microcontroller, thus not much programming knowledge is required. The module consists of three switches to configure the various parameters including ON and OFF trigger temperatures.
