เซนเซอร์วัดน้ำฝนพร้อมสายไฟ Rain / Water Detection Sensor Module

เซนเซอร์วัดน้ำฝน ส่งสัญญาณออกเป็น Analog และ Digital สามารถปรับระดับได้

Specification:

- Working voltage : 3.3V-5V
- Output form: Digital switching quantity output (0 and 1) and analog quantity AO voltage output;
- Small PCB size : 3.2cm x 1.4cm/0.12x0.05 inch
- Function introduction:
- Connect to 5V power supply, the power indicator is on, when there is no water drop on the induction board, the DO output is high level, the switch indicator is off, drop a drop of water, the DO output is low level, the switch indicator is on, brush off the water droplets above, and return to the output high level state.
- AO analog output, can be connected to the MCU AD port detection of the rainfall drop above the size.
- DO TTL digital output can also be connected to the MCU detect whether there is rain.
- Wiring mode:
- VCC: connect to the power positive pole (3-5V)
- GND: connect to the power negative pole
- DO: TTL switch signal output
- AO: analog signal output
