Specification:
The sensor USES the high quality FR - 04 double material, large area of 5.5 × 4.1 CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance;
The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA;
With potentiometer sensitivity adjustment.
The working voltage of 3.3 V to 5 V
The output format: digital switch output (0 and 1) and analog AO voltage output;
Has a fixed bolt hole, convenient installation.
Product use: rain, rain sensor, can be used for all kinds of weather monitoring, and translated into output signals and AO.
Use wide voltage LM393 comparator.
Raindrop Module size: 55 × 41 mm
Small board PCB size: 31.3 x 14 mm
Wire Length: Approx.15cm
Weight: 8.7g
Feature:
Connected to the 5V power supply, the power indicator is on, and when there is no water drop on the sensor board, the DO output is high, the switch indicator is off, and drop a drop of water, the DO output is low, and the switch indicator is on. Brush off the water droplets on it, and then return to the output high level state.
The AO analog output can be connected to the AD port of the single-chip microcomputer to detect the amount of rain falling on it.
The DO TTL digital output can also be connected to the microcontroller to detect whether there is rain.
Wiring:
1. VCC: Connect to the positive pole of the power supply (3-5V)
2. GND: Connect the negative pole of the power supply
3. DO: TTL switch signal output
4. AO: analog signal output
Package Content:
5 x Rainwater Sensor module
