Alternatively, a pressure sensor in the stir bar could potentially measure liquid level based on hydrostatic pressure. It’s a great quality-of-life improvement for regular lab work.

We studied the effect of abnormal thermal stress on a graphene-on-SiC Hall effect sensor dedicated to elevated temperatures. After subsequent thermal stresses at 823, 873, and 923 K provided by rapid ...

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 ...

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 ...
