It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor, an ...

Linear Hall-Effect Sensor. ... Moreover, an output voltage less than 0.4V will be counted as a sensor open-circuit state while higher than 4.2V denotes a sensor short-circuit condition. ... The ...

Hall effect sensors are great, in that they never wear out or get noisy like potentiometers do. Another application where pots are a bad idea is in sensing the tape tension in a magnetic tape drive.

Circuit simulation made easy partsim.com. ... with the help of readily-available and low-cost water flow sensors. YF-S201 Hall-Effect Water Flow Sensor. ... (Yellow) wire of the water flow sensor to ...

Hall-effect sensors are more suited to applications with frequencies higher than 1kHz. These include high-speed sensors for measuring revolutions per minute. Due to the lack of switch hysteresis, the ...
