How the Automated Vehicle Umbrella Tent for Hailstorm Protection works
- 12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V.
- The Temperature sensor measures the temperature that the system monitors or controls.
- The Water / rain level sensor detects the presence or level of water.
- The Arduino Uno R3 reads the inputs, runs the decision logic written in C/C++ and drives the outputs.
- The DC geared motor provides the driving motion.
- The Motor driver lets the low-current controller run the motors forward, reverse and at variable speed.
- The LEDs indicate status.

E&TC / ECE viva questions on this project
What is the aim of the Automated Vehicle Umbrella Tent for Hailstorm Protection project?
An automatic cover that protects a parked car from hail. Rain, temperature and vibration sensors detect the onset of a hailstorm, and a motor unfolds an umbrella-style tent over the vehicle.
Explain the working of your project in short.
12 V power adapter / step-down transformer supplies the circuit; a regulator gives the controller and sensors a steady 5 V. The Temperature sensor measures the temperature that the system monitors or controls. The Water / rain level sensor detects the presence or level of water. The Arduino Uno R3 reads the inputs, runs the decision logic written in C/C++ and drives the outputs.
What microcontroller is on the Arduino Uno and what are its key specifications?
The Uno uses the ATmega328P: 8-bit, 16 MHz clock, 32 KB flash, 2 KB SRAM, 14 digital I/O pins (6 PWM) and 6 analog inputs with a 10-bit ADC.
How does the LM35 temperature sensor work?
LM35 gives an analog output of 10 mV per °C, so 250 mV means 25 °C. The controller reads it with the ADC and converts the value to degrees.
How is water detected by this sensor?
The exposed conductive tracks are open circuit when dry. Water bridges them and lowers the resistance, and the controller reads the change as a level or as rain.
Why is a geared motor used?
The gearbox reduces speed and multiplies torque, so a small DC motor can move a vehicle or mechanism smoothly. Torque increases roughly by the gear ratio.
Why can't the motor be connected directly to the microcontroller?
A motor needs far more current (hundreds of mA to amps) than a controller pin can supply (about 20–40 mA). The H-bridge driver switches the motor current and allows direction control.
Explain the block diagram of your project.
The input section senses the real-world quantity, the Arduino Uno R3 processes it according to the program, and the output section displays the result and drives the actuators. The power supply section feeds every block.
Which communication protocols are used between the modules?
A single-wire digital protocol for the temperature sensor and analog inputs read by the ADC for the analog sensors. Each protocol was chosen because the module supports it and it uses the fewest pins.
What is the operating voltage of the circuit?
The controller and most sensors work at 5 V (ESP boards and some modules at 3.3 V). The battery powers the board, and a regulator steps it down. Motors and relays get their own supply line so they do not reset the controller.
