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 ...

Neopixels and Hall-effect sensors are mounted to custom PCBs that stretch the length of a row and are wired to an Arduino Mega with lots of IO. Game pieces are colorful fridge magnets.

When the door is opened, the magnet moves away from the sensor to generate a wake-up signal to the rest of the electronics. This sensitive and reliable door sensor can be powered from a 9V alkaline ...

The bipolar latching sensors, designated the OMH3075B and OMH3075S Series, contain a Hallogic monolithic integrated circuit, which incorporates a Hall element, a linear amplifier and Schmitt ...

After dealing with years of widespread reports of "stick drift" on the original Switch Joy-Cons, Nintendo watchers have been hoping the Switch 2 would make use of magnetic Hall effect sensors that ...

Diodes' new programmable omnipolar Hall effect switch is optimised to let designers use the same contactless detection circuit in multiple applications or with different field strengths. The miniature ...

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 ...

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 ...
