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 ...

1. Typical application circuit: The device outputs an analog signal (VOUT) that varies linearly with the bidirectional AC or DC primary current, IP, within the ranges specified.

While LEDs are common in voltage detection applications, I have never seen an LED circuit that is dedicated to indicating the presence of low values of current flow. This simple LED current sensor ...

High wattage appliances like electric irons, ovens and heaters result in unnecessary power loss if left ‘on’ for hours unnoticed. Here is a current sensor circuit that senses the flow of current ...

Current sensors measure AC and/or DC current levels. The technology used by the current sensor is important because different sensors can have different characteristics for a variety of applications.

In this article, we will discuss how to measure current using various current sensing techniques with their advantages, disadvantages and applications.

These circuits have been culled from a variety of Linear Technology documents. Each chapter collects together applications that tend to solve a similar general problem, such as high side current ...

ACS712 Current Sensor with Arduino The ACS712 is a popular Hall-effect-based current sensor that provides accurate current measurements in both AC and DC circuits. It is widely used in electronic ...

This current sensor gives precise current measurement for both AC and DC signals. These are good sensors for metering and measuring overall power consumption of systems. The ACS723 Low Current Sensor ...

Common methods used to measure current. A new approach to current sensing: GaNSense technology. For any electrical control system, input signals of both voltage and current are critical for the ...
