Fall detector

Now, let us design another helpful device using the Micro:bit. Elderly people, children, and people with balancing issues are prone to falling while doing their daily activities. Such people require extra attention or a permanent attendee to monitor their movement. This person should monitor their movements and help them in case they fall. Due to a variety of reasons, the presence of an additional person might not be possible 24/7. We can design a fall detector using the Micro:bit that will generate a signal for the other person if the user has fallen. This device can also be used to detect accidents on bicycles or any other fall. In such cases, the device can call for help.

For this experiment, we need to check the range of accelerometer data from the Micro:bit for different movements. We will use the Mu editor and write a simple program to print and plot the accelerometer values for analysis purposes:
