ESP8266 WiFi Air Mouse – Control Devices with Hand Gestures
🔍 Project Overview
This project is an Air Mouse system that allows users to control a computer or smart device wirelessly using hand gestures. The system uses an MPU6050 motion sensor to detect hand movement and orientation. The ESP8266 (NodeMCU) connects via WiFi to send gesture commands to a computer or web-based interface.
When a user moves or tilts their hand, the sensor data is transmitted to the ESP8266, which interprets the gestures and controls the cursor movement, clicks, or scrolling. This creates a touchless, gesture-controlled interface for computers or IoT devices.
⚙️ How It Works (Short & Simple)
🖐️ Gesture Detection
The MPU6050 sensor detects hand movement (tilt, roll, pitch) and orientation.
📡 Sensor Data Transmission
The NodeMCU ESP8266 processes the sensor data and sends it via WiFi to a computer or web interface.
🧠 Gesture Recognition
The software running on the ESP8266 maps specific hand movements to mouse actions, such as moving the cursor, left/right click, or scrolling.
🖱️ Air Mouse Control
The recognized gestures are converted into cursor movements or clicks on the connected device in real-time.
Example actions:
- 👆 Hand tilt forward → Move cursor up
- 👇 Hand tilt backward → Move cursor down
- 👈 Hand tilt left → Move cursor left
- 👉 Hand tilt right → Move cursor right
- ✋ Hand gesture → Left click
- ✌️ Two-finger gesture → Right click
