This project uses a Raspberry Pi and a ultrasonic distance sensor to count the number of bounces on a trampoline. The data is logged to a file for future stats pages, and the live bounce count is displayed on a simple web page.
FYI - you have to run calibrate.py and main.py as sudo for the sensor to work.
git clone https://github.com/ericescobar/BounceCounter.git
Calibrating will do some math to help find the sweet spot of your bounce. (This will help avoid double bounces, or missed bounces)
sudo python calibrate.py
If you want to view the web page place index.html in your root web directory. Mine is /var/www/html/index.html
I installed php/apache2 on my pi using the following Link
sudo python main.py
- If you want the script to run on boot, checkout the systemd .service file
- A log is created which details, bounce, date, time, and distance from sensor (in cm)
- The script will check the log file and sum any previous bounces from earlier in the day. Anything not from the current day won't be counted. (duh).
The following sites helped me get the sensor up and running.
