A Hall effect sensor or Hall sensor is a magnetic non-contact sensor that generates an electrical signal proportional to the magnetic field applied to it. Hall effect sensors are widely used in ...

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 ...

The DHT22 temperature and humidity sensor is a versatile and cost-effective sensor used to measure ambient temperature and humidity for a wide range of applications. It is based on a digital signal ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

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 ...
