Hot selling Raindrop Rain Module Rainleaf Surface Sensor Module High sensitivity Sensor Module Quality Assurance

Brief Introduction

Robot kit, raindrop and rain sensors, can be used for monitoring various weather conditions and converting them into digital signals and AO outputs.

1. The sensor is made of high-quality FR-04 double-sided material, with a large area of 5.0 * 4.0CM and a nickel plated surface, which has superior performance in terms of anti-oxidation, conductivity, and lifespan;

2. The comparator output has a clean signal, good waveform, and strong driving capability, exceeding 15mA;

3. Adjust sensitivity with potentiometer;

4. Working voltage 3.3V-5V

5. Output forms: digital switch output (0 and 1) and analog AO voltage output;

6. Equipped with fixed bolt holes for easy installation

7. Small PCB size: 3.2cm x 1.4cm

8. Using a wide voltage LM393 comparator

Function Introduction

When a 5V power supply is connected and the power indicator light is on, and there are no water droplets on the induction board, the DO output is high and the switch indicator light is off. If a water droplet is dropped, the DO output is low and the switch indicator light is on,

Brushing off the water droplets on top and returning to a high-level output state....

AO analog output can be connected to the AD port of the microcontroller to detect the amount of rainfall dropped on it.

DO TTL digital output can also be connected to a microcontroller to detect whether there is rain.

Wiring method

1. VCC: Connect to the positive pole of the power supply (3-5V)

2. GND: Connect to the negative pole of the power supply

3. DO: TTL switch signal output

4. AO: Analog signal output

Shipping List
