Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

A long-standing mystery in spintronics has just been shaken up. A strange electrical effect called unusual magnetoresistance shows up almost everywhere scientists look—even in systems where the ...

Abstract: The non-contact type application on the permanent magnet and linear Hall-effect sensor gauging rotary system is introduced in this paper. For such a contactless case, there is no wear. This ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...

The MLX90296 contactless linear sensor combines digital flexibility, ultra low power consumption, adaptable polarity modes, and a space-saving form factor. Melexis has announced the MLX90296, a new ...

Melexis unveils the MLX90296, a new micropower linear Hall-effect sensor that draws less than 5 µA at 100 Hz and integrates digital filters for enhanced performance. Its flexible architecture is ...

Think of a keyboard switch like light switches. They have a fixed point where they activate, and all they can report is whether they're in one of two states. Hall effect switches are more like light ...

The TMAG5134 in-plane Hall-effect switch offers a viable alternative to existing position sensors that carry higher costs and greater manufacturing complexity. Texas Instruments (TI) has announced the ...
