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 ...

This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

Allegro MicroSystems, Inc. announces an open loop Hall-effect sensor IC with near closed loop performance (in accuracy and bandwidth). Allegro's ACS716 current sensor ICprovides an economical and ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Earlier, we designed a smart energy meter that used a current sensor to measure current. In that version, we manually set the ...

Designed for AC or DC current sensing for motor control, switched-mode power supplies and solar invertors, the devices have a low-offset, linear Hall sensor circuit with a copper conduction path ...

Use of 4-to-20-mA current loops involves more than just a simple series connection between sensor, display, and power supply. The point where a sensor takes a measurement is, at times, many yards away ...

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current ...

Allegro MicroSystems has turned to tunnelling magnetoresistance (TMR) technology to make a 10MHz bandwidth current sensor with 50ns response time. “Our TMR technology is enabling current sensors that ...
