The “YFS201 Hall Effect Water Flow Sensor” comes with three wires ... This is used to read the output pulses coming from the water flow sensor. When Arduino detects the pulse, it immediately triggers ...

The very simplest magnetic sensors are reed switches ... you can see the battery providing the current flow and the meter measuring the Hall effect voltage as the horseshoe magnet applies ...

A pair of Hall effect sensors are mounted in the ... measure the angles of the pantograph’s joints. The Hall sensors are read by an Arduino Nano, which computes the angles into movement of ...

Melexis applies this concentrator as a back-end deposition to the normal CMOS-process flow. After the flux concentrator presents the B-field to the integrated Hall-effect sensor, a differential-analog ...
