RAIN WATER ALARM | SCHOOL PROJECT | WORKING MODEL with explanation

by

Introduction:

This video demonstrates the working of a rain alarm system that you can use it in your school project by doing it yourself. The experiment can be easily adapted and used in homes and industries too.

A rain alarm is a smart water detector, it detects rain and automatically triggers an alarm or buzzers. This alarm is used to alert and hence save and harvest rain water.

Rainwater detectors are used in irrigation, home automation, and automobiles.

Questions and Answers:

  • What are the applications of rain water alarms?

The rain is detected in irrigation, this alerts the farmer to collect the water. In automobiles it helps inform the driver and automatically turn on the wipers.

In households it serves the role of a detector to save water. It is also used to detect chemical rain. It boosts the power of antennas in communication and hence increases the signal strength.

  • Where are these alarms found?

These alarms are found in use at both domestic and industrial facilities. These alarms are triggered by the minutest droplets of water and an alarm is set on.

This gives the user ample time to retrieve possessions, shut windows and in some cases prepare to harvest the rain.

Thus, the alarm prevents the rain from entering homes, offices, and silos.

  • What are the components of rain alarm systems?

There are multiple components that come into play when a rain alarm is discussed. They are small rain censors, 555 timer IC, transistor, bright white LED, PN junction diode and a resistor.

Conclusion:

It is a cost-efficient way to save water and help harvest rain at the right time. Rain is the purest form of water. The video helps us understand and make a rainwater alarm.
