Description:
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 sensor uses the FR-04 high-quality double-sided materials, King Size 5.0 * 4.0CM, and with the surface of the nickel plating treatment, against oxidative, conductivity, superior performance and longevity, The output in the form: of digital switching outputs (0 and 1) and analogue AO voltage output. TTL-level output, TTL output valid signal is low. Driving capability 100MA so can directly drive relays, buzzer, a small fan, and so on. Sensitivity can be adjusted via a potentiometer. LED lights up when there is no rain output is high, raindrop up, the output ground level, LED light.

How To Use:
- Connected to the 5V power supply, the power indicator light, sensor board is not water droplets, DO output is high, the switch lights off, dropping on a drop of water, DO output is low, the indicator light switch,
- Brush off the above water droplets, which have returned to output high state.
- AO analogue output can be connected to the microcontroller AD port to detect the size of the drops in the above rainfall.
- DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain.
Pin Description:
- VCC: positive power supply (3-5V)
- GND: a negative one.
- DO: TTL switching signal output
- AO: Analog signal output
Package Included:
- 1 x Rain-sensing board
