W1209 50~110°C 12V DC Digital Thermostat Temperature Control Switch Sensor Module

Description:

This is an 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 the 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 the 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
