Water Level Sensor Switch Module for Arduino 3 Pack Simple, reliable water level detection modules designed for DIY electronics and microcontroller projects. Each pack contains three identical switchstyle water level sensors that detect the presence of liquid and provide a clear, usable signal for control and monitoring. Key benefits Easy integration with Arduino and other microcontrollers: connects directly to a digital input for straightforward monitoring and control. Quick detection for practical control tasks: ideal for triggering alarms, pumps, or indicators when liquid is detected. Ready for DIY use: compact modules that fit well on breadboards and inside small enclosures, speeding up prototyping and deployment. Costeffective multipack: three identical modules included to support multiple sensor points or spare units for projects. Main features and attributes Function: switchstyle water level detection that indicates when liquid contacts the sensing traces on the module. Compatibility: works with Arduino and most microcontroller platforms that accept simple digital signals. Size and form factor: compact PCB modules suitable for breadboard prototyping and compact installations. Material and construction: standard PCB construction with exposed sensing traces for liquid detection. Performance: responsive detection suitable for common monitoring and control applications in hobby and light industrial projects. Typical applications Water tank level monitoring and basic pump control for small systems. Leak detection under appliances, in basements, or inside enclosures to trigger alerts. Aquarium and hydroponic hobby projects to monitor water presence and automate refills. What you get Three water level sensor switch modules per pack, ready for wiring into your Arduino or microcontroller project. Notes Intended for hobbyist and general electronic applications. Verify wiring and signal levels with your controller before connecting.
