Raindrops module / rain sensor module / sensor module large raindrops

descriptionvoltage: 5V power indicator, output signal LED indicator. TTL level output, TTL output valid signal is low driving capacity of around 100MA, can directly drive a relay, buzzer, small fan, and so on. Sensitivity can be adjusted via a potentiometer no rain when the LED is lit the output is high, raindrop up, ground level output, LED lights. Raindrops board and control board are separate, easy to wire leads. A large area of rain board, is more conducive to detected rain. Board with positioning holes to facilitate installation of the control panel board size: 3 * 1.6 MM large raindrop detection plate 5.4 * 4.0 MMTwo usewhen connected to the 5V power supply lights, no water induction plate, DO output is high, switch lights off, dripping a drop of water, DO output is low, switch lights, brush the top of the water droplets , has returned to output high state. . . . AO analog output can be connected to the microcontroller AD port to detect drops in the above rainfall size. DO TTL digital outputs can also be connected to the microcontroller to detect whether there is rain.Three shipping listFigure 1 raindrop sensor board and a control board shown in each2 20cm DuPont line 5, easy to wire3 provides information Download (Schematic + test program)
