Out-of-range current measurements with current-sense amplifiers Measuring Current to Detect Out-of-Range The hall effect sensor is more costly and complex to implement. An advantage to using the hall effect sensor method is its ability to work with higher current and it provides electrical isolation if a particular device has multiple sources of power. In this article, we will focus on building a current sensor circuit using a current sense resistor.
Flux Gate Sensor Current Sensing Method. A saturable Inductor is the main component for the Fluxgate sensing technique. Due to this, Fluxgate sensor is called as Saturable Inductor Current Sensor. The inductor core which is used for the fluxgate sensor works in the saturation region.

current to an easily measured output voltage, which is proportional to the current through the measured path. There are a wide variety of sensors, and each sensor is suitable for a specific current range and environmental condition. No one sensor is optimum for all applications. Among these sensors, a current sensing resistor is the most Acs712 current sensor can measure both direct and alternating current. For this post/tutorial/project I am going to measure only dc current. Formula which i derived and explained in the tutorial is only for direct current measurement. You can not use the below formula to measure alternating current with acs712 hall effect current sensor.
The typical current of such a circuit would be at around 0.020A. Since the smallest current range of the ACS712 is 5 Ampere, you will not get much of a signal on the sensor output. In this tutorial, we explored how to use the ACS712 current sensor with an Arduino to measure both DC and AC currents. By understanding the working principle of
Current Sensor : Working, Interfacing & Its Applications Circuit Diagram
The typical application circuit using the ASC712 Current Sensor is given in its datasheet and the following images shows the same. ACS712 Current Sensor Module. Using one of the variants of the ACS712 IC (5A, 20A or 30A), several manufacturers developed ASC712 Current Sensor Module boards that can be easily interfaced to a microcontroller like Hall effect current sensor circuit Using Arduino helps to monitor and log current flow to a device. Here the ACS712 current sensor ic placed in a breakout board and connect with Current sense target load and Micro-controller. The sensor detects current flow through IP+ and IP- pins (Resistance Current Conductor), it creates hall effect and then proportional voltage output taken form pin 7
