Revolutionize your journey with Robotshapers, shaping a brighter future on the roads. Rain sensing wipers, are designed to increase driver safety and comfort by activating and adjusting wiper speed accordingly.These systems usually have rain sensors mounted on the windshield to detect the presence and use of rain. Rain sensors use various technologies such as optical sensors or capacitive sensors to monitor the humidity of the air.
When rain is detected, the automatic wiper system sends a signal to the wiper motors telling them to turn on the wipers at the appropriate speed. The system constantly monitors rainwater and adjusts the wiper speed to provide the best view for the driver. Some advanced automatic wiper systems also include additional features such as variable speed settings that change the frequency of  the wipers depending on the rain.Automatic wiper systems make it a common feature in modern vehicles, providing convenience and  safety by reducing driver distraction and increasing visibility in the rain.

Components required:

2. LCD (16X2)
3. 10K variable resistor
4. LM393 Rain sensor
5. 5V DC power supply
6. SG90 Servo

LM393 Rain sensor:

The LM393 rain sensor is a special type of rain sensor that uses the LM393 comparison circuit. It has moisture sensitive features such as water absorbing data or electronic signals and analog LM393 chip. Humidity sensor detects rain by changing the function or resistance when it rains on it. This change is converted into an electrical signal.The LM393 comparison chip compares the signal from the rain sensor to a preset voltage.

When the signal exceeds the voltage indicating rain, the comparator outputs a logic high or low signal. The output of LM393 rain sensor can be connected to other electronic devices or systems for additional operation or control. For example, it can be used to make car windshield wipers or to block water in the rain. The LM393 rain sensor provides a simple and cost-effective solution for rain applications. Its integration with the LM393 benchmark chip provides reliable monitoring capabilities, making it widely used in many industrial and automation applications.

Applications:

Automatic wiper systems, commonly known as automatic windshield wipers, have many uses in the automotive industry and  beyond. Here are some key applications:

1. Automotive Industry: Automatic wipers are widely used in automobiles to improve safety and driving convenience. They catch  the rain from the window and adjust the speed to get the best view in different weather conditions.
   
   
2. Public Transportation: Automatic wipers are indispensable in buses, taxis and other public transportation vehicles. It increases  the driver's field of vision and improves the safety of the passengers in bad weather conditions.
3. Construction and Mining Equipment: Heavy machinery such as excavators and loaders are often equipped with automatic  wipers to provide visibility in dense open areas, prevent accidents and increase productivity.
   
   
4. Marine Industry: Automatic wipers are used to keep the windshield clean on boats to ensure safety in bad weather in puddles.
   
   
5. Transportation: Train drivers rely on automatic wipers to keep the windshield clean and improve visibility to keep trains moving  safely, especially in rain and snow.
   
   
6. Aviation: Airplanes use automatic wipers to clear rain, snow or other debris from the windows, allowing pilots to have a clear view during takeoff, landing and aircraft.
