This is DIY project that ” HOW TO DETECT A RAIN “must Do it by yourself especially for the beginners. Here, the analog output (AO) of the rain sensor module is Connected with analog input (A0) of the Arduino, so that the Arduino chip can read an analog voltage between 0 and 5 volts to process a number between 0 and 1023.

When it is raining (Arduino detects it) D8 output of the Arduino board goes to “High” level (5v) and will turn on the buzzer or load if you are using a Relay and if D8 output goes to Low level (0v) will turn of the Buzzer/relay.

    This is really very nice idea. Thank you for sharing with us. Compression load cell has two types like CMP of monolith Construction, CMP-SP. Each has made with high nickel alloy steel. Some of the applications compression load cell used in object weighing, production lines, test systems and Torque supports.
