Using a Hall Effect Sensor with Arduino

Hi guys, welcome to today’s tutorial. Today we will look at how to use a hall effect sensor with Arduino. A hall effect sensor is a sensor that varies its output based on the presence or absence of a magnetic field. This means that the output signal produced by a Hall effect sensor is a function of magnetic field density around it. When the magnetic flux density around it exceeds a certain pre-set threshold ...

Researchers From NREL Discovered New Method To Develop Rechargeable Magnesium-metal Battery

A team of researchers from National Renewable Energy Laboratory (NREL) has discovered a new method for developing a rechargeable non-aqueous magnesium-metal battery. A proof-of-concept paper published in Nature Chemistry. It described how the scientists pioneered a method to enable the reversible chemistry of magnesium metal in the noncorrosive carbonate-based electrolytes and tested the concept in a protot ...

Broadcom AFBR-S50 ToF laser light sensor measures up to 10 meters

The AFBR – S50 is a multipixel distance and motion measurement sensor. It has an integrated 850nm vertical cavity surface emitting laser (VCSEL) which uses a single voltage supply of 5V. It’s measurement rates are quick and as fast as 3 kHz, which is a distinguishing feature. However, this is not the reason why the AFBR – S50 stands out. It is different because unlike other Time of Flight (ToF) ranging sens ...

DC-DC converter starts up and operates from a single photocell

The bq25504 from Texas Instruments is a good candidate to become a milestone on the road to micro-power management and energy harvesting. A prominent feature of this IC is its ability to start up at a supply voltage as low as 330 mV typically, and 450 mV guaranteed. With an SMD inductor and a few capacitors and resistors, it forms a dc-dc converter with a high power efficiency that is unprecedented, especia ...
