Where electronics enthusiasts find answers. This converts current value to proportional voltage value. The ACS712-5 is a hall-effect current sensor chip whose output is an analog signal proportional to the current passing through the chip. Be the first to review “20A CURRENT SENSOR MODULE ACS712 Arduino module” Cancel replyCancel reply. The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die. The sensor can even measure high AC mains current and is still isolated from the measuring part due to integrated hall sensor. Thick copper conductor and signal traces allows for survival of the device up to 5 times overcurrent conditions. 4V will correspond to the zero current point. The 20A Range Current Sensor Module ACS712 consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die.
