20A Range Current Sensor Module ACS712

Description

The ACS721 current module is based on the ACS712 sensor, which can accurately detect AC or DC current. Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc.

The 20A ACS712 Range Current Sensor Module consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportional voltage. 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.

• Current sensor chip: ACS712ELC-20A
• Pin 5V power supply, on-board power indicator
• The module can measure the positive and negative 20 amps, corresponding to the analog output 100mV / A
• There is no detection current through, the output voltage is VCC / 2

Note: ACS712 is based on the principle of the Hall test, please use this field to avoid an impact!
