HW-038 Water Level and Humidity Sensor (Liquid Detection Module)

The HW-038 liquid level and humidity sensor module is designed to detect water or measure the degree of moisture on a surface. The device operates by detecting changes in electrical resistance between the parallel tracks on the board when moisture is present. The sensor outputs data as an analog or digital signal, making it easy to integrate into various circuits based on microcontrollers (for example, Arduino) for leak protection systems, water level monitoring in tanks, or automatic plant watering. Features: Product type: liquid level and humidity sensor Specifications: HW-038 model, printed circuit board with parallel conductive tracks, analog and digital outputs, power LED indicator Purpose: water leak detection, control of reservoir filling levels, and creation of automatic watering systems
