Learn — Current Sensor

The ACS712 Current Sensor module is a very popular module for measuring the current applied in the circuit due to its capabilities and its price.  In this article, we will talk about how to wire and set up the module for operation with an Arduino Board.  Wiring  Most ACS712 modules operate at 5V and produce an analog voltage output proportional to the measured current. For this project, we use a power supply (giving output voltage from 0 to 5V), and a resistor to generate current from 0 to 5 A. There are a few versions of the ACS712 Module in the market, but...
