Pulse Electronics Corp. has unveiled a 50 Hz/60 Hz, di/dt AC current sensor that can be clamped onto an existing solid conductor without having to disconnect the conductor. The PA3828NL clamp-on ...

There are a lot of ways to measure energy usage in the home, but most of them involve handling mains voltage. Not only that, but sometimes they require handling mains voltage before it gets through a ...

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current ...

While LEDs are common in voltage detection applications, I have never seen an LED circuit that is dedicated to indicating the presence of low values of current flow. This simple LED current sensor ...

This compact mains voltage sensor is intended to monitor and signal to another circuit, for instance a microcontroller, about the presence and/or absence of the ac mains voltage. For this task, a ...

Melexis has brought out the latest variant from its IMC-Hall current sensor – the MLX91218 Low Field (LF). The MLX91218-LF is designed for lower current applications (below 100 A). It enables smart ...

ABB has launched its latest generation Fiber Optic Current Sensor (FOCS-FS) to complement its portfolio of optical sensors. The FOCS-FS gets its name from its ‘free standing’ design. A salient feature ...
