Rain sensor module


The rain sensor uses an FR-04 high-quality double sided PCB for widest possible sensing of raindrops, it uses an LM393 low voltage comparator with output driving ability over 15mA. Operating voltage of this module varies between 3.3 volts to 5 Volts, best to supply 5 V from the Arduino power pins.

The item is for Arduino robot kit, raindrops, rain sensor, monitoring can be used for a variety of weather conditions, and converted into the number of the reference signal and the AO output.

The output pins include a digital output (0 and 1) and analog AO voltage output.

The digital output can be used to directly drive relays, buzzer, a small fan, and so on. Sensitivity for the digital output can be adjusted via the potentiometer.

Rain sensor module specification:

Small board PCB size: 3.2cm x 1.4cm
Operating voltage: 3.3V-5V
Voltage: 5V

Connection mode:

1, VCC: positive power supply (3-5V)
2, GND: negative
3, DO: TTL switching signal output
