Crash Test Sensor

View Cart

The Crash Test Sensor interfaces the ADXL278 dual-axis high-g accelerometer to an Arduino-compatible microcontroller. It detects up to +/-50g of acceleration, making it perfect for reading out data on impact.

Output from the Crash Test Sensor is measured in mV/g, and typically operates at +5V, accepting a maximum of +7V. The board is also equipped with a self-test pin.

The Crash Test Sensor comes as a kit with 2 6-pin male headers, and it can be used for a variety of projects to measure the threshold level of impact before damage occurs.


  • DIY crash test dummy
  • Robotic crash detection
  • Recording impact levels in sports (hockey, baseball)
  • Gauging effects of impact/acceleration on human body
  • Earthquake or vibration measurements
