Description
Full Description
The W1209 Temperature Control Switch Module delivers precise thermal management in an ultra-compact footprint. Designed for both hobbyists and industrial prototypers, this module allows you to intelligently control power to most types of electrical devices based on the temperature sensed by the included high-accuracy NTC temperature probe.
Despite its small size and low cost, the W1209 operates with an onboard microcontroller (MCU), meaning no advanced programming is required to get started. It features a simple three-button interface (SET, +, -) to configure the trigger temperatures and access a menu of seven hidden parameters (P0–P6), allowing users to adjust heating/cooling modes, hysteresis, upper/lower limits, and calibration. The onboard relay can handle loads up to 10A, making it highly capable of driving fans, heaters, peltier coolers, and other high-draw components.
Key Features
-
Dual Operating Modes: Easily switch between Heating (triggers relay when temperature drops) and Cooling (triggers relay when temperature rises) modes.
-
High-Precision Sensing: Comes equipped with a waterproof NTC (10K 0.5%) sensor on a 50cm cable, allowing for safe liquid or enclosed-space temperature monitoring.
-
Onboard Memory: Retains your programmed settings and threshold values even after power loss.
-
Clear Visual Feedback: The bright 3-digit, 7-segment LED display provides real-time temperature readings alongside an onboard LED indicator that lights up when the relay is actively closed.
-
Industrial Build Quality: Features 100% machine patch components and wave soldering for stable, long-term performance.
