Abstract
A microcontroller operated module is affixed to a firearm. The module includes an accelerometer for measuring the G force of each round fired by the firearm, a flash memory (non-volatile memory) for storing the shot profile data that includes shot count and recoil data and transmitting it to a remote location such as a remote computer via a serial communication device pursuant to RS232 standard, Bluetooth, a wave or other low power RF transmitter. The module including a wake up circuit adapted to switch upon detection of a fired shot to signal said microcontroller to initialize a low power mode to activate said MEMS accelerometer faster than said accelerometer would activate by itself.
