The comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA.
Adjust sensitivity with potentiometer.
Voltage: 5V.
Output form: digital switch output (0 and 1) and analog AO voltage output
with fixed bolt holes for easy installation.
Usage: Connected to 5 v power supply power lights, no water droplets on induction plate, the DO output for the high level, switch lights out, a drop of water drops, the DO output for the low level, switch indicator,brush away the water droplets, return to again, the output high level state. AO analog output, can be connected to the microcontroller AD mouth drops of rainfall in the above size. DO TTL digital output can also be connected microcontroller detecting whether it will rain.
Package include: 6 x Rain drops sensor board 6 x Control board 6 x Cable wires
