ADXL377 used with Schmitt triggers

Thread Summary

The user is new to electronics and wants to use an ADXL377 accelerometer to trigger another component based on specific acceleration thresholds (8G for x-axis, 12G for y-axis, 18G for z-axis) using Schmitt triggers. The final answer confirms that using Schmitt triggers for each axis is a reasonable approach and advises checking the Sensitivity and Zero g bias levels in the ADXL377 datasheet for accurate voltage output values. The ADXL377 has a 1.5V output at 0G, with -200G and +200G corresponding to 0V and 3V, respectively.

Hi everyone

I'm really new to electronics and am looking to use an ADXL377 accelerometer to activate another component when a certain acceleration is detected, so was thinking of using a Schmitt trigger for each axis of acceleration which would provide the voltage required for the other component to operate when the acceleration reached a certain value (for reference, the accelerations to trigger the component would be 8G for x-axis, 12G for y-axis or 18G for z-axis). Is this the best way to make the circuit work?

Also, my understanding of the ADXL377 is that the output voltage is 1.5V at 0G, so -200G would give an output of 0V and +200G would give an output of 3V. Is this correct?

Any advice or suggestions would be much appreciated!

Thanks in advance :)
