(Dih)rone Simulator

This project implements a multi-sensor telementary circuit using ESP32 microcontroller . It compiles all the real-time environmental and motion data that revolves around the drone and helps you visualise the drone in a 3️D environement replicating the same environment.

Hardware Components

• ESP32 Microcontroller 🧠
• Accelerometer --> ADXL345🚅
• Ultrasonic Sensor --> HC-SR04📡
• BMP180🎈
• DHT11🌡️
• LDR Sensor☀️

Required Libraries

• Wire
• Adafruit_Sensor
• Adafruit_ADXL345
• Adafruit_BMP085
• DHT

Working

Step 1 - Initialization

• As soon as the whole circuit starts, the micrcontroller initializes the Serial conncection and verifies the connectivity of the different sensors like ADXL345 and BMP180.

Step 2 - Data Acquisition

• After the establishment of the connection, different data sets are received from different sensors, like

1. Motion - Captures 3-axis acceleration from the ADXL345.
2. Proximity - Measure the bstacles in the vicinity using the ultrasonic sensor (HC-SR04).
3. Environment - Reads the meteorological elements, it reads the temperature and humidity using DHT11 and barometric pressure and altitude using BMP180.

Step 3 - Data Formatting & Transmission

• The collected data is compiled and structred into a JSON file that is sent to the backend of the webpage, where that JSON file is parsened and all the data is extracted from it and is displayed.

💻Software Interface

This project includes a companion web application that visualizes the real-time telemetry data streamed from the circuit. The dashboard parses the JSON output from the Serial port and displays it.

🔨Tech Stack --> HTML5, CSS3, and Three.js

📊Data and Logic

1. Motion (ADXL345) --> X-Y acceleration tilts the 3D cube on the screen.
2. Light (LDR) --> If light % is less than 50% => Night Mode (Dark Background)
3. Distance (Ultrasonic Sensor) --> If distance < 20 cm => Warning (Red Background).
4. Atmosphere --> Displays Altitude and Pressure.
