W1209 Digital Temperature Controller Thermostat Module
The W1209 Digital Temperature Controller Module is a compact and easy-to-use thermostat board designed for automatic temperature control in heating and cooling systems. It uses a microcontroller-based control system together with a high-precision NTC temperature sensor to provide accurate and stable temperature regulation.
The module features a clear 3-digit LED display, simple button operation, and a relay output for controlling external loads such as heaters, fans, refrigerators, or incubators. Because of its small size, low cost, and reliable performance, the W1209 is widely used in DIY projects, incubators, aquarium controllers, and temperature control boxes.
