Flow meters have proven excellent devices for measuring water flow, and now it is very easy to build a water management system using the renowned water flow sensor YF-S201. This sensor sits in line ...

The flow meter allows a hard limit to be set for the maximum amount of water allowed into the tank. He’s used an Arduino Micro to tie the project together, which also handles a real-time clock ...

Note that with the “DFR” sensor, we get a signal output very close to VCC (in digital mode) when the sensor is not submerged or is in clear water (and a bit lower than that in analog mode). Here’s one ...
