This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

Isolation in this case, is from the mains, and it transpires that finding something that will do the job safely is tricky. Three isolated Hall-based current sensing modules are easy to obtain, as far ...

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Racer series, ...

Allegro MicroSystems has announced a family of current sensor ICs for AC or DC current sensing with 200kHz bandwidth and 2.5µs response time – “the fastest response time of an IC ever offered in the ...
