METHOD AND DEVICE FOR LOW-POWER ACCELERATION DETECTION IN A TELEMATICS DEVICE

A method and a device for low-power acceleration detection in a telematics device are provided. The method includes putting the telematics device into a sleep mode and performing a first micro wakeup. In response to determining that a first value read from a sensor during the micro wakeup is greater than a noise threshold, increasing a frequency of the micro wakeups and a sampling rate of the sensor. The method also includes reading a second value from the sensor during a second wakeup, performing a regular wakeup, and sending the first and second values during the regular wakeup.
