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 ...

There is an integrated magnetic Hall-Effect sensor that outputs an electrical pulse with every revolution. The “YFS201 Hall Effect Water Flow Sensor” comes with three wires: Red/VCC (5-24V DC Input), ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Would you believe it, the ESP32 popular Wi-Fi and Bluetooth chip has a built-in Hall effect sensor. Espressif Systems makes the chip, and its ESP32 data sheet has nearly no mention of the Hall sensor ...

Allegro Microsystems has introduced isolated differential current sensor ICs based on the Hall effect. Accuracy is typically +/-1% from 25 to 125°C, and +/-3% from -40 to +25°C. Both the ACS724KMA ...
