COMPLETE 20-PACK SET: Each package includes 20 individual water level sensor modules with red PCB boards, exposed parallel wire traces for detection, and standard 3-pin interfaces clearly marked for signal, power, and ground connections.
ANALOG SIGNAL DETECTION: Measures liquid presence and depth through exposed parallel wire traces that change analog output signals based on water volume, allowing microcontrollers to interpret precise moisture levels and liquid depth variations.
DURABLE CONSTRUCTION: Features securely soldered surface-mount components for consistent electronic performance across all units. Operating voltage of 3.3V to 5V DC ensures compatibility with most microcontroller platforms and prototyping boards.
SIMPLE WIRING SETUP: Connect the ground pin to your board's ground, power pin to 3.3V or 5V output, and signal pin to an analog input port. Partially submerge the trace area into liquid while keeping top components dry, then clean and dry thoroughly after use to prevent corrosion.
VERSATILE APPLICATIONS: Perfect for engineering students and DIY electronics enthusiasts building moisture monitoring alarms for basements, smart home leak detection systems, automated plant watering projects, or plumbing drip pan monitors with Arduino or Raspberry Pi controllers.
