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

Abstract: The estimation of rotor position is fundamental for the commissioning of magnetically-levitated drives. The sensors required for this measurement must be close to the rotor, often requiring ...

In this paper, we designed a group of horizontal Hall sensors in 0.35 µm BCD (bipolar/CMOS/DMOS) technology. Compared with the existing Hall devices, the design has improvement in parts such as Hall ...
