Description
Rain Alarm Project is a simple but very useful project that detects Rain (Rain Water) and automatically triggers an alarm or buzzer so that we can make some actions and save the rainwater. As a result, we can increase the water levels of underground water by using the underwater recharge technique. This Rainwater detector will detect the rain and make an alert; rain water detector is used in the irrigation field, home automation, communication, automobiles, etc. Here is the simple and reliable circuit of rain water detector which can be constructed at low cost.
The Sensors Based Rain Alarm Project is the resistance between the wires will be very high and there will be no conduction between the wires in the sensor. If there is rain, the water drops will fall on the rain sensor which will also decrease the resistance between the wires and wires on the sensor board will conduct and trigger the NE555 timer through the transistors circuitry. Once NE555 is triggered, it will make the output pin high and which will make the buzzer make an alarm.
