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 ...

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 ...

Paragraf, a leader in graphene-based electronic sensors and devices, has demonstrated the ability of its graphene Hall Effect sensors to withstand high levels of radiation. Testing by the National ...
