Title: | rain sensor arudino module |
Package: | RAIN SENSOR ARUDINO MODULE PCB |
Description: | How it works: The rain sensor detects water that completes the circuits on its sensor boards' printed leads. The sensor board acts as a variable resistor that will change from 100k ohms when wet to 2M ohms when dry. In short, the wetter the board the more current that will be conducted. Pins: A0.......... Analog output D0......... Digital output GND..... Ground VCC...... Positive voltage (input: 5v for analog 3.3v for Digital.) |
