Why do we need rain alarms?
Water is a basic need in every one’s life. Saving water and proper usage of water is very important. Rain water detector will detect the rain and make an alert; rain water detector is used in the irrigation field, home automation, communication, automobiles etc.
What is the principle of rain alarm?
When it rains, water drops falls on the rain sensor, which decreases the resistance between the wires. As a result wires on the sensor sheet starts conducting and trigger the NE555 timer IC through the transistor circuitry.
How does a rain alarm circuit works?
The heart of rain alarm circuit is rain sensor which is used to detect the presence of water. When rain drops falls on the sensor, it creates a conducting path and triggers the 555 Timer IC. Once the timer IC is triggered, it will activate the alarm.
What is rain water detector?
Rain water detector is a simple circuit which detects the rain and makes an alert. Rain water detector is used in the irrigation field, home automation, communication, automobiles etc. Rain water detector is a simple circuit which detects the rain and makes an alert.

How do you make a rain alarm step by step?
How does a water alarm work?
At its simplest, a water alarm, also called a water leak sensor, is a small device about the size of a garage door opener placed on the floor near any place a leak might occur. The alarm has a sensor that detects water and triggers the control panel to sound an alarm, loudly in the home or via a phone alert.
Which animal is known as rain detector?
African Bush Elephant in Mikumi National Park, Tanzania. Taken by Oliver Wright, via Wikipedia. A team of researchers working in Nambia has found that elephants are able to detect rain storms from distances as far away as 150 miles.
What is the use of transistor in rain alarm?
Using ordinary silicon transistors, the circuit is basically a handy flasher circuit that operates well on only 3V. The buzzer is pulsed about once per second for a very short time when the circuit is triggered giving a dripping water sound. By increasing the capacitor value, a longer and slower beep may be obtained.
What is the alarm circuit?
Fire Alarm Circuit is a simple circuit that detects the fire and activates the Siren Sound or Buzzer. Fire Alarm Circuits are very important devices to detect fire in the right time and prevent any damage to people or property.
Is the rain alarm project a good idea?
RAIN ALARM PROJECT 2 Chapter No:-2 INTRODUCTION Rain Alarm Project is a simple but very useful project that detects Rain (Rain Water) and automatically triggers an alarm or buzzer. Water is a basic need in every one’s life. Saving water and proper usage of water is very important.
What’s the purpose of a rain water alarm?
AIM OF THE PROJECTThe primary aim or purpose of the project are- 4.1To Conserve Waterthere is a lot of water that you can save by using a rain sensor. By automatically turning off your lawn irrigation system every time it rains, the conserved water can be used in other essential purposes such as fighting fire.
How does a rain detector work in a house?
The sensor is able to detect even the slightest water and will sound an alarm when exposed to rain. The main objective to be achieved in this project is to produce an alarm to help users alert more quickly to avoid the presence of rain from wet shirt at clothesline outside the house.
What is the significance of a rain sensor?
1.2 SIGNIFICANCE OF THE PROJECT A rain sensor is an automated device that shuts off your lawn irrigation system every time it rains. It is a relatively cheap device that can save up to 45 percent of your water bills, help protect the environment and conserve water.
