In this project, we are going to build a flow meter sensor and pressure sensor using Arduino and displaying it on a LCD display. Flow sensor has a rotor and a Hall effect sensor. When fluid flows ...

Ensure #define _DEBUG is set. Connect the flow meter up to a hose and get a measuring jug. Slowly open the tap and measure out 500mL of water and compare that to what you're seeing in the debug.

For powering the ESP32-S3 we have used the ADP1706 ultra low noise LDO, and for the reset circuitry we have used the ADM803 power supervisory chip. We have also included a provision for a 1.28” round ...
