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 ...

Melexis has added the MLX91231, a shunt-based sensing automotive current sensor for IVT (current, voltage, and temperature) and a digital microcontroller (MCU). The sensor is designed to measure low ...

A version of thie article appeared in the February 2012 issue of Test & Measurement World. See the PDF. Many industrial systems use the 4–20-mA loop to transmit measurements from sensors to displays, ...

Anyone who’s ever tried their hand at reverse engineering a piece of hardware has wished there was some kind of magic wand you could tap on a PCB to understand what its doing and why. We imagine ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

In Part 1, we covered the basics ofsensors and the characteristics youmust keep in mind when using them in designs. However, there isan enormous range of specialist sensors developed for ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...
