This project is a wearable embedded system designed to promote better ergonomic health by monitoring the user’s posture in real-time. It detects both back tilt and neck bend using onboard sensors and provides immediate feedback through visual and audio alerts. The system is built around the ESP32 microcontroller and leverages its BLE capabilities for future extension into mobile-based logging and alerts.
The Smart Posture Monitoring System enhances posture awareness through:
- Tilt detection using an MPU6050 sensor (accelerometer + gyroscope)
- Neck bending detection using a Flex Sensor
- Posture classification into multiple levels based on sensor thresholds
- Real-time alerts using an LED and buzzer for corrective feedback
- (Future scope): Integration with a mobile app over Bluetooth for data logging and insights
| Component | Purpose |
|---|---|
| ESP32 | Main controller with built-in Wi-Fi and BLE |
| MPU6050 | Detects body tilt via accelerometer and gyroscope |
| Flex Sensor + Resistor | Measures neck bend via voltage divider circuit |
| LED | Provides visual feedback on posture |
| Buzzer | Emits audio alert on poor posture |
| Jumper Wires, Breadboard | Circuit assembly and prototyping |
- The MPU6050 measures the user's pitch angle to assess back posture.
- The Flex Sensor detects bending of the neck by monitoring resistance.
- Posture is classified into:
- Good
- Moderately Bad
- Bad
- Very Bad
- Alerts are generated as follows:
- LED lights up to indicate posture issues.
- Buzzer provides real-time audio feedback for correction.
AnglePitch: 28.56
