CXAC Command - Accelerometer Threshold
Configures the trigger threshold for movement and/or acceleration detection by the accelerometer built into Rinho.
What is it used for?
| Use case | Description |
|---|---|
| 🚗 Impact detection | Alert collisions or strong hits |
| 🚨 Anti-theft | Detect vehicle tampering |
| 📊 Driving analysis | Measure harsh braking and acceleration |
| 🔔 Device wake-up | Activate device by movement |
Description
This threshold will be the resulting vector sum of the acceleration calculation, taking ZERO threshold as the gravity itself, meaning any acceleration change will be detected without considering gravitational acceleration.
The trigger will be reflected by the AC trigger (See SS Command).
Values referring to the calculated acceleration components can be obtained through the AC Command.
