Schematic of the ACS712 Current Sensor Circuit (tested circuit diagram of the current sensor module) The internal resistance of this conductive path is 1.2 mΩ typical, providing low power loss. The do ...

INA219 Module & Arduino – First Test Admittedly, there is nothing new or special about the INA219 module as there are countless tutorials/projects out there that exploit its ability to measure both dc ...

Current sensor rejects PWM for motor control Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce ...

Allegro Microsystems has introduced isolated differential current sensor ICs based on the Hall effect. Accuracy is typically +/-1% from 25 to 125°C, and ...
