+[Product URL - Rain Water Drop Sensor](https://www.electrodragon.com/product/water-drop-rain-sensor/)
6
+
7
+## Product Use:
8
+
9
+Arduino robot kits, rain drop/rain sensors. Can be used for monitoring various weather conditions and converting them into digital signals and AO output.
10
+
11
+## Product Introduction:
12
+
13
+1. The sensor uses high-quality FR-04 double-sided material, with a large area of 5.0\*4.0CM, and the surface is treated with nickel plating, which has superior performance in terms of anti-oxidation, conductivity, and service life.
14
+2. Comparator output, the signal is clean, the waveform is good, and the driving ability is strong, exceeding 15mA.
15
+3. Equipped with potentiometer to adjust sensitivity.
16
+4. Working voltage 3.3V-5V
17
+5. Output form: Digital switch output (0 and 1) and analog AO voltage output.
18
+6. Equipped with fixed bolt holes for easy installation.
19
+7. Small board PCB size: 3.2cm x 1.4cm
20
+8. Uses wide voltage LM393 comparator
21
+
22
+## Function Introduction:
23
+
24
+Connect to a 5V power supply, the power indicator lights up. When there are no water droplets on the sensing board, the DO output is high level, and the switch indicator is off. Drop a drop of water, the DO output is low level, and the switch indicator lights up. Brush off the water droplets, and it returns to the high-level output state.
25
+
26
+The AO analog output can be connected to the AD port of the microcontroller to detect the amount of rain falling on it. The DO TTL digital output can also be connected to the microcontroller to detect whether it is raining.
27
+
28
+## Wiring Method:
29
+
30
+1. VCC: Connect to the positive pole of the power supply (3-5V)
31
+2. GND: Connect to the negative pole of the power supply
32
+3. DO: TTL switch signal output
33
+4. AO: Analog signal output
