Picture of Pool Pi Guy - AI Driven Alarm System and Pool Monitoring Using Raspberry Pi

Having a pool at home is fun, but comes with great responsibility. My biggest worry is monitoring if anyone is near the pool unattended (especially younger kids). My biggest annoyance is making sure the pool water line never goes below the pump entry, which would run the pump dry and destroy it costing $$$ in repairs.

I have recently figured out how to use a Raspberry Pi with OpenCV and TensorFlow, along with a water level sensor and a solenoid valve to resolve both issues - and have fun doing it!

It turns out to also be a great alarm system too - motion activated, AI-controlled, infinitely customizable.

Let's dive in.

Step 1: Grand Plan

In this instructable we will show how to:

  1. Setup a Raspberry Pi with OpenCV and TensorFlow
  2. Connect a Webcam through a long USB cable
  3. Write an OpenCV algorithm to detect motion
  4. Use TensorFlow for object detection
  5. Set up a web server on the Raspberry Pi to show the interesting images
  6. Integrate with IFTTT to trigger mobile alerts in case a person is detected
  7. Attach a relay HAT to the Raspberry Pi and connect it to a solenoid valve that would add water to the pool
  8. Attach a water level sensor to the Raspberry Pi and interface with it using the Pi's GPIO
  9. Write some code to glue it all together
