Description:

Arduino robot kit, rain drops, rain sensor, can be used for a variety of weather conditions monitoring, and into a fixed signal and AO output.
Made of high quality fr-04 double-sided material, with a super large area of 5.0x4.0CM, and has a nickel-plated surface, which has superior performance in anti-oxidation, electrical conductivity and service life.
Comparator output, clean signal, good waveform, strong driving ability, over 15mA.
With potentiometer to adjust sensitivity.
Use wide voltage LM393 comparator.
Fixed bolt holes are provided for convenient installation.

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

Package Includes:

1 Piece Raindrops Sensor Module
