W1209 Digital Temperature Controller Thermostat Sensor

This is XH-W1209 12V Digital Temperature Controller Module W/ Display and NTC Waterproof Temperature Sensor.

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 the W1209 module, which is highly functional and low cost can help you to invent such minor yet amazing automation in your home.

W1209 thermostat module has a temperature sensor, keys, LED display, relay and requires DC 12V power supply. It 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. 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. W1209 has an inbuilt embedded micro-controller, thus not much programming knowledge is required. The module consists of three switches to configure the various parameters including ON and OFF trigger temperatures. The relay can operate at voltages up to a maximum of 240V AC at 5A or 14V DC at 10A to power on. The temperature is displayed in degree centigrade and with the help of a 7-segment display and the relay, the state is displayed with the help of the LED present on the W1209 module.

w1209 digital temperature controller Mini thermostat Temperature controller is a low-cost 12V Temperature controller with a 7-segment display and 3 switch keypads for setting temperature and other parameters. The module features an NTC thermistor temperature sensing and has an accuracy of 0.1 C.

The XH-W1209 12V Digital Temperature Controller Module W/ Display and NTC Waterproof Temperature Sensor is an incredibly low cost yet highly functional thermostat controller. With this module, you can intelligently control power to most types of electrical devices 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 onboard relay can switch up to a maximum of 240V AC at 5A or 14V DC at 10A.

Vayuyaan believes in satisfied customers, so whatever the product is, we first import them then test them for their supplier-defined and standard capabilities. Only after doing all the possible quality checks, we make the product available to our customers.

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.
