W1209 Digital Temperature Controller Module

• The W1209 is a compact, low-cost temperature controller module commonly used in DIY and industrial applications for regulating temperature within a predefined range.
• It features an NTC 10K waterproof temperature probe that provides fast and accurate temperature readings.
• The module includes a high-current relay that can switch heating or cooling devices directly, such as heaters, fans, refrigerators, incubators, or water pumps.
• Users can easily configure temperature setpoints, hysteresis, high/low temperature limits, and calibration using three onboard push buttons.
• The bright LED display shows real-time temperature and menu parameters, making setup and monitoring simple.
• The controller supports both heating mode (relay activates when temperature drops below setpoint) and cooling mode (relay activates when temperature rises above setpoint).
• Ideal for thermostats, incubators, pet habitats, aquariums, fermentation systems, and general temperature regulation tasks.
