MATRIX
Water/Drop_Detection Sensor Module
- High Cost Performance Ratio
- Calibration of Sensitivity
- Standard 3-Pin Interface
- PCB dimension (mm): 16 x 60
Matrix-Water_Sensor is a simple and straightforward-to-use water/drop detection module. It detects water and drops, and converts the amount to analog signals. Its sensitivity can be calibrated with the potentiometer. It works with all Friendly Elec boards, Raspberry Pi and Arduino boards.
The module has a series of exposed traces. The resistance of these exposed traces are proportional to the water level. This mechanism is used to measure the amount of water and therefore calculate the water level. It can be used to detect whether or not there is rainfall as well.
