An intelligent water consumption meter system has been designed. The measurement system has been developed using Cypress Semiconductor PSoC4TM system-on-a-chip. The hardware part has been designed to perform water flow measurements, temperature and pressure monitoring. Developed Android application has been used to communicate with hardware using the Bluetooth LE interface. Overpressure detection procedure was developed to prevent emergency cases. The user has been able to monitor water use in real-time, configure system remotely and control external pipe valve.
Advanced mode has been added to reset measuring results, select liquid type and recalibrate system should it be necessary.
