This allows the ACS722 and ACS723 current sensor ICs to be used in high-side current sense applications without the use of high-side differential amplifiers or other costly isolation techniques.

Designed for low-power applications with high output-voltage swings at low currents, Allegro MicroSystems Europe’s ACS722 and ACS723 current-sensor ICs deliver high accuracy along with internal ...

[lingib]’s dual sensor echo locator uses two HY-SRF05s, but the cheap and plentiful HC-SR04s will work, too. Both sensors are arranged for maximum beam overlap and wired up to an Arduino Uno.

Silego Technology’s 2.0 x 3.0 mm CurrentPAKTM SLG6M6001V enables high accuracy current measurement in a highly configurable 10 A, 3.8 mΩ RDSON Load Switch.

As current passing through the sensor increases, the resistance needs to go down to maintain the same thermal losses (due to the system imbalance). Similarly, designers using fluxgate technology to ...
