Description

Rain Sensor Water Drops Rain Detector Module

Product Description:

1. The size of the PRINT COVER: 3.2 cm X 1.4 cm

2. Voltage: 3.3V ~ 5V

3. output as: digital switching outputs (0 and 1) and analogue AO voltage output

4. Output comparator, the signal is clean, good signal, the ability to drive a car is strong, for more than 15 ma

5. sensor USES high quality FR-04 double material, large area 5.5 * 4.0 CM, nickel and surface treatment, there is a fight of oxidation, electrical conductivity, and life has better performance

6. Fixed bolt hole for easy installation

7. The sensitivity can be adjusted with a potentiometer

8. Board with positioning holes for easy installation

9. Wide Voltage LM393 Comparator

how to use

1. Connected to 5 V power supply, power indicator, the sensor of the board does not drop water, DO output has a high level, switch off light, drops on the water drop, DO output low, indicator switch,

2. Shake off the above drops of water, returned to the output high state.

3. AO analog output can be connected to the microcontroller AD port to determine the droplet size in the above precipitation.

4. NO TTL digital outputs can be connected to the microcontroller to detect whether there is rain.

connection mode

1. VCC: Positive power supply (3-5V)

2. EARTH: negative power supply

3. MAKE: TTL output switching signal

4. AO: Analog output signal
