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 ...

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 ...

The paper represents an accurate and economic low range (up to 5 A) ac current sensing scheme using high precision ACS712 hall-sensor. ATmega microcontroller is used in processing signal and for ...

Sometimes you need to know the temperature of something from a ways away. That might be a smoker, a barbecue, or even a rabbit hutch. This project from [Discreet Mayor] might just be what you’re ...

Wannier-Berri calculates Brillouin zone integrals very fast with high precision over an ultradense k-grid. This is achieved due to : Using Fast Fourier Transform account of symmetries, to reduce ...
