Sensor Uses high quality FR – 04 double material, large area of 5.0 c 4.0 CM, treatment of nickel plated surface to fight oxidation, electrical conductivity and promote longer lifespan.
The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma.
Built in potentiometer for sensitivity adjustment.
Working voltage of 3.3 – 5V.
Output format: digital switch output (0 and 1) and analog AO voltage output;
Has a fixed bolt hole for convenient mounting
PCB size: 3.2 cm x 1.4 cm.
When there is no water on the sensor, the DO output is HIGH. When water is present, the DO output is LOW.
DO TTL digital output also can connect to the single chip microcomputer to detect whether there is rain.
1. VCC: positive (3-5 v)
2. GND: connect power anode
3. DO: TTL switch signal output
4. AO: analog signal output
