Project Title: ESP32 Ultrasonic Distance Measurement with Web Server
Project Description:
In this project, we harness the capabilities of the ESP32 microcontroller to create a versatile distance measurement system using an HC-SR04 ultrasonic sensor. Our goal is to accurately measure distances in three different units: centimeters, inches, and meters, and display the results on an LCD screen.
Components Used:
- ESP32 Dev Module Microcontroller.
- HC-SR04 Ultrasonic Sensor.
- Liquid Crystal Display (LCD) with I2C Interface.
- Various LEDs and a Buzzer for Alerting.
- Breadboard and Jumper Cables.
Project Overview:
-
Hardware Setup:
- Connect the HC-SR04 ultrasonic sensor to the ESP32 microcontroller.
- Set up the LCD display to show distance measurements.
- Configure LEDs and a buzzer for visual and auditory alerts.
-
Distance Measurement:
- Utilize the HC-SR04 sensor to accurately measure distances in centimeters using ultrasonic waves.
- Convert these measurements into inches and meters for added convenience.
-
Real-Time Display:
- Display the distance measurements in real-time on the LCD screen.
- The LCD will show the distance in centimeters, inches, and meters.
-
Alert System:
- Implement an alert system based on distance thresholds.
- Visual alerts will be given through LEDs, with different LEDs lighting up for different proximity levels.
- Auditory alerts will be provided using a buzzer.
-
Local Web Server:
- Configure the ESP32 to act as a local web server.
- Access the distance measurements and alerts via a web browser.
- Utilize the GET and POST protocols for interaction with the web server.
Project Benefits:
- Versatile Distance Measurement: This project offers distance measurements in three different units, making it suitable for various applications.
- Real-Time Monitoring: Users can monitor distance measurements in real-time via the LCD display and a web interface.
- Alert System: The system provides alerts for different distance ranges, enhancing safety and awareness.
- Local Web Server: The local web server allows for remote monitoring and control of the system.
This ESP32-based distance measurement and web server project showcases the capabilities of the ESP32 microcontroller and provides a practical solution for applications such as home automation, robotics, and security systems.
