5A Range Current Sensor Module ACS712
The 5A Current Sensor Module ACS712 features a precise, low-offset, linear Hall effect circuit with a copper conduction path near the surface of the die. When current flows through this copper path, it generates a magnetic field, which the Hall IC then converts into a proportional voltage.
Current sensing and control are essential for various applications, including overcurrent protection, battery charging, switch-mode power supplies, digital wattmeters, and programmable current sources, among others.
This ACS712-based current module is capable of accurately detecting both AC and DC currents. It can measure currents up to 5A, with the resulting current signal available for reading through the analog I/O port of an Arduino.
