W1209 Digital LED Thermostat Temperature Controller On/Off Switch Control relay Module Waterproof NTC Sensor

The W1209 temperature controller is a compact, versatile, and reliable temperature control module widely used for DIY and industrial applications. Designed to deliver precise control, it supports a wide temperature range from −50°C to +110°C with a 0.1°C resolution (−9.9°C to 99.9°C) for accurate operation.

Powered by 12V DC, it features a waterproof NTC 10K sensor probe that allows stable readings even in humid or liquid environments, making it suitable for aquariums, incubators, refrigerators, and heating/cooling projects. The 10A relay supports both AC and DC loads, enabling you to directly control fans, heaters, water pumps, and other appliances.

The LED display ensures easy monitoring, while programmable parameters such as hysteresis, delay start, and temperature calibration provide flexibility. With low power consumption and a compact size (~48×40 mm), this module is a favorite among hobbyists and professionals alike.
