Since I have a basement and the foundations needs to be emptied sometimes, especially during the rainy seasons, I've developed a web application that runs on Tomcat + Java 7 that allows the user to check the water level (using Ultrasonic Sensor HC-SR04) and activate remotely the pump (using Relay board). Also some sort of push notifications notifies the user if some given limit has been trespassed.

| HC-SR04 Sonar sensor |
