The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

Overcurrent relays with inverse definite minimum time (IDMT) characteristics are widely used in power systems to protect ...

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 ...
