ACS712 ACS 712 5A / 20A / 30A Current Sensor Module Hall Effect for Arduino ASC 712 Techmakers

Accurate sensor to measure AC/DC current up to 5A/20A/30A. The sensor can even measure high AC mains current and is still isolated from the measuring part due to integrated hall sensor. The board operates on 5V.

ACS712 current sensor operates from 5V and outputs analog voltage proportional to current measured on the sensing terminals. You can simple use a microcontroller ADC to read the values.
