W1209 50~110a C 12v Dc Digital Thermostat Temperature Control Switch Sensor Module

This is XH-W1209 12V Digital Temperature Controller Module W/ Display and NTC Waterproof Temperature Sensor. W1209 Mini thermostat Temperature controller is a low-cost 12V Temperature controller with a 7-segment display and 3 switch keypad 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. The current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an onboard LED.

How To Use:
Connect the power supply and the load, you can supply to the controller
It is displayed as a measured temperature
Press the SET button, the display flashes the temperature
Press - to set the desired temperature
After setting press SET to confirm return
The controller automatically performs the relay by setting off

Lights, LED Status Descriptions:
Indicator: Off The relay is switched off, Always indicate the relay is closed.
LED: Shows LL is the sensor open, showing HH is out of range, the thermostat will be forced to close the relay, the display --- as high-temperature protection.

Application:
To measure and display temperature
Turn any application ON/OFF based on temperature reading. (Both AC and DC)
Example Project:- A. Fire alarm system. B. Auto cut off Electric Water Heater
