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 ...

A decent current measurement sensor ought to be an essential part of every hacker’s workbench. One that is capable of measuring DC, as well as low and high frequencies with reasonable accuracy.

A sensor that I somehow missed, despite it being a popular building block in module form is the WCS1800 current sensor from Winson of Taiwan. It is part of a large family of current sensors from the ...

These iso-amps can also provide isolated temperature and current sensing. Fig. 1 shows a typical inverter in an ac motor drive. The inverter converts the dc bus voltage to ac power at a ...

Sensor-less brushless dc motors do not have to be hard to ... A4963, as the chip is called, needs three n-channel – p-channel mosfet pairs to switch motor current, plus a dc supply of 4.2 to 50V. The ...
