PosturePal is a wearable IoT device that tracks your spinal alignment in real time — vibrating the moment you slouch, and pushing a notification to your phone when you ignore it.
What it does
Two MPU6050 gyroscopes measure the angle between your upper and lower back continuously — no delay, no guessing.
The moment bad posture is detected, a vibration module activates on the device — a silent, immediate reminder right on your back.
If you stay slouched, the NodeMCU's WiFi fires a Web Push notification to your phone. No app download — just add to home screen.
Tune the angle threshold from the web dashboard. The Arduino polls the server and updates live — no re-flashing, no cable needed.
