The output in the form: digital switching outputs (0 and 1) and analog AO voltage output
The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA
The sensor USES the high quality FR - 04 double material, large area of 5.5 * 4.0CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance
A fixed bolt hole for easy installation
Sensitivity can be adjusted via potentiometer
Board with positioning holes to facilitate installation
Wide voltage LM393 comparator
How to use
Connected to 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 the above water droplets, has returned to output high state.
AO analog 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.
