E&TC / ECE viva questions on this project
What is the aim of the IoT Temperature & Mask Scan Entry System For COVID Prevention project?
An automated entry gate for COVID safety. A contactless sensor checks temperature and a camera checks for a mask; entry is allowed only if both pass, and records are uploaded online.
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 Camera module captures images or video for recognition and monitoring. The Raspberry Pi 4 runs Linux and the main program, handles the camera, networking and heavier processing such as image recognition.
Why did you choose a Raspberry Pi instead of an Arduino?
The Raspberry Pi is a full computer with an operating system, so it can run Python, OpenCV and a web server. An Arduino is a microcontroller that is better for simple real-time control but cannot process images or run multiple programs.
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 the camera image processed?
Frames are captured and processed with OpenCV: converted to grayscale, filtered and passed to a detection or recognition model that labels faces, objects or number plates.
How is 230 V AC converted to 5 V DC for the circuit?
A transformer steps down the voltage, a bridge rectifier converts AC to pulsating DC, a capacitor smooths it and a 7805 regulator gives a steady 5 V.
Explain the block diagram of your project.
The input section senses the real-world quantity, the Raspberry Pi 4 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). A 12 V adapter powers the board, and a regulator steps it down. Motors and relays get their own supply line so they do not reset the controller.
What is the difference between accuracy and precision?
Accuracy is how close a reading is to the true value. Precision is how close repeated readings are to each other. A sensor can be precise but inaccurate if it is not calibrated.
How do you ensure patient safety?
The device runs on low-voltage batteries, has no direct mains connection to the patient, uses isolated sensors and limits current through any electrode. Alarms are set for abnormal readings.
