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 ...

I got a couple of INA 219 modules from an online seller overseas. I was looking for a different dc current sensor module to start a small battery charger project, so I welcomed them. The INA219 based ...

霍尔传感器（Hall Effect Sensor）是根据霍尔效应制作的一种磁场传感器，当恒定电流通过内部的霍尔半导体片时，将在垂直方向产生电位差即霍尔电压。这个霍尔电压随磁场强度的变化而变化，磁场越强，电压越高，磁场越弱，电压越低。虽然霍尔电压很小，通常 ...

Featuring DC to 5-MHz bandwidth, Allegro MicroSystems' galvanically isolated, high-accuracy magnetic current-sensor IC with zero current reference (ACS37030), and overcurrent fault with internal pull ...

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 ...
