How much impact can the human body handle? Whether it's football, rock climbing, or a bicycle accident, knowing when to seek immediate medical attention after a collision is incredibly important, especially if there are no obvious signs of trauma. This tutorial will teach you how to build your very own impact force monitor!

System Alert

This open-source project uses a Raspberry Pi Zero W and an LIS331 accelerometer to monitor and alert the user of potentially dangerous G-forces. Of course, feel free to modify and adapt the system to suit your various citizen science needs.
