In the water level sensor schematic, the common probes connecting the underground tank and the overhead tank to +9V supply are marked ‘C’. The other probe in underground tank, which is slightly above ...

Arduino (Sparkfun RedBoard) code and schematic for water level sensor using reed switches. A floating magnet will trigger these switches as the water level rises or falls causing the voltage to change ...

This project is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...
