Hall Effect Current Sensor Module ACS712

This module senses the current and provides a proportional output voltage suitable for inputting into a microcontroller. The module features a power indicator and is capable of measuring up to 5A.

Input voltage: 4.5V to 5.5V

Measures -5 to +5A current, corresponding simulation output: 185mV/A

Output voltage is VCC / 2 when no current is measured
