The Hall Magnetic Sensor project showcases how to use an Arduino Nano to detect a magnetic field with a Hall sensor. This project will light up an LED when a magnetic field is detected. It is useful ...

ACS712 Current Sensor with Arduino The ACS712 is a popular Hall-effect-based current sensor that provides accurate current measurements in both AC and DC circuits. It is widely used in electronic ...

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

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 ...

Abstract: This system is designed to get vehicle speed information on the highway. Because the speed of a vehicle on the highway is very influential on other road users. Even based on data taken by ...
