W1209 Temperature Controller

W1209 Digital Temperature Controller Module:
The W1209 Temperature Controller is a versatile, low-cost, and reliable digital thermostat module designed for precise temperature measurement and control. It features an NTC thermistor sensor, an onboard relay, and a bright 3-digit LED display that provides real-time temperature readings and setpoint adjustments.
This module allows users to easily set temperature thresholds and automatically activate or deactivate heating or cooling devices based on the configured limits. With user-friendly push buttons, the W1209 offers adjustable hysteresis, temperature calibration, and delay start functions, making it suitable for a wide range of DIY, industrial, and automation applications.
It can be directly powered by a 12V DC supply and is compatible with heaters, fans, and cooling modules. The onboard relay can handle loads up to 14A at 125V AC or 10A at 250V AC, making it ideal for controlling high-power devices safely.
