Hello friends, I hope you all are doing great. Today, I am going to share the Raspberry Pi 5 Water Meter and Leak Detector - Proteus Simulation , the twentieth project of our IoT Projects series. If you have searched for a Proteus simulation of a smart water meter or a water leak detector with a Raspberry Pi, here is a complete one. A Raspberry Pi 5 counts the pulses of a YF-S201 water flow sensor on the pipe into a house, works out the flow and the litres, logs every use of water, and shuts a 12 V solenoid valve through a relay when the water behaves like a leak or a burst pipe. An LCD, a buzzer and a live web dashboard show what it sees. A dripping tap is easy to notice, but a running toilet cistern, a pinhole in a pipe behind a wall or a hose left on in the garden can waste thousands of ...
