⚙️ Working Principle
⚡ MEMS Capacitive Sensing
  • Uses Micro-Electro-Mechanical Systems (MEMS) capacitive sensors
  • Acceleration changes distance between tiny internal plates → capacitance change
  • Internal circuitry converts capacitance → analog voltage
🔄 Axis Measurement
  • X, Y, Z axes measured independently
  • Analog voltage outputs are proportional to g-force
Vout=Vzero−g+(Acceleration×Sensitivity)V_{out} = V_{zero-g} + (Acceleration × Sensitivity)Vout​=Vzero−g​+(Acceleration×Sensitivity)
  • Vzero−g≈VCC/2V_{zero-g} \approx V_{CC}/2Vzero−g​≈VCC​/2
  • Sensitivity: ~300 mV/g (typical)
