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 ...

A family of IC-based ac current sensors from Silicon Laboratories provides a smaller, lower-loss alternative to conventional current-transformer (CT) circuits used to control and protect power systems ...

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 ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Pulse Electronics Corporation introduces its new Sidewinder™ AC current sensors. Sidewinder products differ from traditional current sense transformers because they do not need a core. This makes them ...
