The aim of the project was to design and test a prototype of a system that can be attached to a trampoline to sense impacts caused by jump movement. The system will detect the movement and store the number of jumps to a counter, which value is sent to a mobile application.
The system is comprised of the following main components: a piezo electronic sensor, a filter circuit which is used to modify the raw signal from the piezo sensor, a microcontroller that will detect the jump movement from the sensor signal and send the number of jumps to a mobile application.
The main goal of the project was to extract the correct number of jumps when attached to the trampoline. Several prototypes was designed and tested in order to evaluate the performance of the different types of filter circuits and the position of the sensor. The final system designed was able to successfully detect jump movement and the number of jumps in a specific test scenario. However, in the future, the performance of the system could be improved smart motion detection algorithm, efficient power management, and versatile internet connectivity.
