W1209 consists of the temperature sensor and also contains display. this controller is the incredibly low-cost temperature controller. Temperature and power controller W1209 is a highly functional thermostat controller. You can also control power with this module. Users can control the power of most of the electrical devices which are based on the temperature sensed. And it is included high accuracy NTC temperature sensor. The microcontroller is embedded in the temperature controller module. And this module did not require any programming.
This module also consists of 3 tactile switches. Which allows for the configuration of various parameters. this module switch included On OFF trigger. 240V AC at 5A and 14V DC at 10A is the maximum configuration to switch up onboard relay. The temperature on the temperature module displayed in centigrade.
