ACS712 20A Current Sensor Module

Description

The ACS712 20A Current Sensor Module is based on the Allegro ACS712ELCTR-20A bi-directional hall-effect current sensor chip that detects AC or DC current. The maximum AC or DC that can be detected can reach 20A, and the present current signal can be read via the analog I / O port of Arduino. The board operates at 5V DC and the current flow through the sensor is converted to an output voltage starting at 1/2Vcc (or 2.5V) for no current flow and moves up 100mV per amp for positive current or down -100mV per amp for the negative current.

Specifications:-
Supply Voltage: 4.5V ~ 5.5V DC
Measure Current Range: -30A ~ 30A
Sensitivity: 100mV/A

Note: ACS712 is based on the principle of Hall detection. Please avoid the influence of magnetic field when using the module.
