A Raspberry Pi Pico combined with a BME280 sensor can create a small Pico Altimeter that measures data like elevation and air pressure.

If you’ve ever wanted a simple, automated way to schedule pet feeding reminders or alerts, the Pico 2 W can help. This project involves using a small servo to trigger a chute, latch, or gravity-fed ...

Hall based current sensors are widely used in AC and DC high current sensing. Current in busbar generates magnetic field which is directed to hall sensor using a surrounding magnetic core. This paper ...

This paper presents an analytical model to address the scenarios of positioning errors for both Hall sensors and phase windings. This model is capable of demonstrating the qualitative features of ...

Build a device that will check whether your door is locked, using a Raspberry PI, a hall effect sensor and a small but strong (preferably neodymium) magnet. It will store the results in a cloud ...
