Maintaining a pool is going to be much easier when you have a smart pool monitor. Drop happens to be a smart pool monitor that continuously monitors your pool water quality and helps you keep it clean and safe. Just throw the device into your pool and use the companion app to receive feedback. The device has an accelerometer that alerts you when it detects suspicious movement.
The Drop app will be compatible with iOS and Android devices. You can monitor up to 3 pools with it. The app lets you monitor chlorine, pH, temperature, movement, and water quality. Did we mention that the device has a solar panel, so you never have to charge it? Yet another fascinating Kickstarter project.
