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 tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing ...

Current sensing remains a challenge and while most engineers use DCR current sensing it is notoriously inaccurate. So what can be done to improve accuracy? The buck converter is the most common power ...

Resistor-based current sensing is simple, easy to use, low cost, extremely linear and requires no calibration. The statement that voltage across a resistor is directly proportional to the current ...

A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up ...

Why low-side current sensing is still widely used. Why a precision preamplifier is critical to low-side current-sensing performance. Sensing current flow through a load or from a source is a common, ...

What qualities are needed for current sensors in an automotive environment? Warren Pettigrew spells out the requirements. Today what is expected of automotive sensors is quite different to what was ...
