This document describes an automatic rain sensing wiper system using a 555 timer circuit. The system uses a rain sensor that activates when water drops are detected. This triggers the 555 timer circuit, which turns on a transistor. The transistor then activates a relay that powers the wiper motor, causing the wipers to turn on when rain is falling. The system automatically detects rainfall and activates the wipers to clear the windshield without manual operation. It can provide convenience but requires additional installation costs for vehicles.
The rain-light sensor supports the field of vision of the driver by detecting the amount of rain and the amount of light and functioning automatically.

The project is developed to avoid the human errors while taking a reverse extensively used for parking the vehicle. In this project we use ultrasonic sensors which can efficiently detect the obstacles and the solenoid valve perfectly controls the braking system by using Arduino programming.
This project has reduced the tension of the driver and also reduced the cost involved in the concern. The project has been designed to perform the required task by taking minimum time.
The future technology of automobile industry "The Intelligent Reverse Braking System". A study and Technical Paper Presentation by me provides you to understand the concept and gives clear view of the Reverse Braking System.
The study has been carried out with proper research papers of the concerned authors which has helped me to present well in Technical Paper Presentation during my final year of Graduation.

IR Based Vehicle With AUTOMATIC BRAKING and DRIVER AWAKENING System (2014)
In this Project When any obstacle comes in front of the vehicle in a fixed range then the automatic brakes are applied and the vehicle sounds an alarm and also a very small current is produced on the steering of the vehicle. If the vehicle met with an accident then a call is generated on the last dialled number from the phone which is placed in the vehicle.
Automatic Monitoring of Soil Moisture and Controlling of Irrigation SystemEswar Publications
In past couple of decades, there is immediate growth in field of agricultural technology. Utilization of proper method of irrigation by drip is very reasonable and proficient. A various drip irrigation methods have been proposed, but they have been found to be very luxurious and dense to use. The farmer has to maintain watch on irrigation schedule in the conventional drip irrigation system, which is different for different types of crops. In remotely monitored embedded system for irrigation purposes have become a new essential for farmer to accumulate his energy, time and money and will take place only when there will be requirement of water. In this approach, the soil test for chemical constituents, water content, and salinity and fertilizer requirement data collected by wireless and processed for better drip irrigation plan. This paper reviews different monitoring systems and proposes an automatic monitoring system model using Wireless Sensor Network (WSN) which helps the farmer to improve the yield.

In this project the pneumatic bumper and brake is used to protect the man and vehicle. This system is only activated when any obstacle comes in front of vehicle, the obstacle is sensed by sensor and it gives the signal to the control unit and due to this bumper system and braking system activated. Bumper is energized by compressor and it compressed the air and send it to the pneumatic piston. This system is used in any type of light vehicles.

3. A rain sensor or rain switch is a
switching device activated by rainfall.
RAIN SENSOR
4. How rain sensing wipers work?
• Working of this circuit is same as the working principle of mono stable multi
vibrator. Here the trigger to the second pin is given by rain sensors.
• A small water drop on the rain sensor will connect the negative voltage to the
trigger pin of 555 IC which in turn will turn the output pin of 555 high.
• 555 Output is connected to the base of transistor through a 1K resistor which
forward biases the transistor. Thus relay gets negative and it switches ON the
wiper motor.
8. Functioning:
Relay:
• Relay is also a switch that connects or disconnects two circuits.
• But instead of manual operation a relay is applied with electrical signal, which in
turn connects or disconnects another circuit.
Rain sensor:
• A rain sensor or rain switch is a switching device activated by rainfall.
• A small water drop on the rain sensor will connect the negative voltage to the
trigger pin of 555 IC which in turn will turn the output pin of 555 high.
Wiper motor:
• A wiper motor is used to wipe off the rain water on the glass with the help of
the principle that is "when ever a current carrying conductor is placed in a
magnetic field, it experiences a mechanical force“.
9. MERITS:
• Wiper automatically gets activated
when there is Rain or if there is
some water on the windshield.
• This circuit automatically detects
the rainfall and activates the wiper
to clear the windscreen.
• This system can be implemented in
common economic cars.
10. DEMERITS:
•This system is applied in case of water
falling on glass only.
• Addition charges are required to
install this system
to four wheelers.
