Product Usage:
Robot kit, raindrop, rain sensor, can be used for monitoring various weather conditions and converted to digital signal and AO output.
Function Description:
Connect the 5V power supply, the power indicator is on, when there is no water drop on the sensor board, DO output is high, the switch indicator is off.
When there is a drop of water on the sensing board, DO output is low level, switch indicator light, brush off the water drop on it, and it returns to output high level state.
AO analog output, can be connected to the AD port of the microcontroller to detect the size of the rain drops on it.
DO TTL digital output can also be connected to the microcontroller to detect whether there is rain.
Wiring Mode:
1. VCC: connected to the power supply positive (3-5V)
2. GND:connect the negative power supply
3. D0:TTL switch signal output
4. A0:Analog signal output
