20A ACS712 Current Sensor
The 20A ACS712 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. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportional voltage.
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.

ADDITIONAL RESOURCES
1. What is current sensor ACS712?
- The ACS712 is a current sensor that can work in both AC and DC modes. This sensor runs on 5V and outputs an analog voltage proportional to the measured current. This tool is made up of a series of precision Hall sensors connected by copper lines.
2. Can ACS712 measure AC current?
- The ACS712 current sensing module includes the ACS712 IC, which uses the Hall Effect principle to measure DC/AC current. It is simple to use with microcontrollers like Arduino because it only has three pins, two of which are power supply pins and the other is an analog output pin.
3. How use ACS712 current sensor with Arduino?
- The ASC712 Current Sensor Module board's screw terminals are linked in series with the motor and power supply. Then connect the VCC, GND, and OUT of the ASC712 board to +5V, GND, and A0 of Arduino. Now, in order to view the results, a 16×2 LCD is connected to Arduino.
4. What is the purpose of current sensor?
- A current sensor is a device that detects and converts current to a measurable output voltage proportional to the current flowing through the measured path. There are many different types of sensors, and each one is designed for a specific current range and environmental condition.
