High-g Impact Sensor
This project involved the development of a High-g impact sensor for testing composite structures.
The resulting sensor was able to measure impacts up to 200g using the ADXL372 3-Axis MEMS Accelerometer from Analog Device
After an impact, the maximum impact registered was displayed on the OLED screen.
