“Using this to manage a water sensor. Joined it up to a zero sized prototyping board and got a buzzer, RGB LED and connector for the sensor all packaged up in Pi zero case. So neat and tidy even my wife approved of it. Software senses the water and sounds the buzzer, flashes the LED, emails me and also sends push notifications to my phone until the water level goes down. All I need it to do now is fix the dodgy immersion tank overflow that sometimes freezes in bad weather. Great little board. Got plans to use one for a smart garage door opener next.”
