Monitor voltage and current with the Tiny V/A Meter

Measuring voltage and current is an important part of the development process for any hardware product. Especially when developing a low power device, the knowledge of how much power the device is drawing at each mode of its operation is critical to the correct estimation of its battery...

DIY voltage and current reference

Petteri Aimonen designed and built his own voltage and current reference: When developing a data acquisition system, I ran into a need of having fairly accurate current reference to compare against, 0.1% accuracy or better. This is not a particularly high standard, but unable to find a...

Low-cost current monitor tracks high dc currents

Susanne Nell @ edn.com has a design idea on how to measure high dc currents. To measure high levels of direct current for overload detection and protection, designers frequently use either a current-shunt resistor or a toroidal core and Hall-effect magnetic-field sensor. Both methods...
