How to determine the g value from adxl377 based on action/ shcok. or how to verify the g value received from accelerometer--adxl377.
The sensitivity of the ADXL377 is nominally 6.5mV/g so the output will change by 6.5mV for every g the accelerometer experiences. However, you also have to account for initial offset. The output of the XL377 with no acceleration is 1.5V (for a 3V supply) and the change from 1.5V is either positive of negative depending on the direction of the acceleration. There will be part to part variation in both offset and sensitivity and you can refer to Table 1 and the charts in the datasheet for min/max values. You can also calculate the sensitivity of an individual sample by placing it in 1g and 0g fields and calculating the difference.
I have moved this discussion over to MEMS Inertial Sensors community. Someone here should be able to answer your query.
