Can ACS712 measure AC voltage?

ACS712 is a Hall Effect-Based Linear Current Sensor it can measure both DC(Direct Current) and AC(Alternating Current). The sensor chip is made by Allegro www.allegromicro.com. Pin out and Pin description of the chip is below.

What is the output of ACS712?

The features of ACS712 include: 66 to 185 mV/A output sensitivity. Low-noise analog signal path.

Which sensor is used to measure current?

Magnetic Current Sensor
Magnetic Current Sensor. The principle of the magnetic current sensor is that the current to be measured generates a magnetic field around the current path, and by detecting this generated magnetic field using a magnetic sensor, the amount of the current can be measured.

How to measure AC current with Arduino and acs712?

You can combine this project with this one: Easy measure of AC Voltage using Arduino and ZMPT101B Tests will be done on an incandescent light bulb, controlled by a light dimmer in series with a reference multimeter and the ACS712 current sensor module.

Where can I find an acs712 sensor module?

The ACS712 can be found in modules, which facilitate their connection, bring a terminal block to connect the line we want to measure and 3 pins, two to connect the power and a pin for the analog output.

How to use acs712 Hall effect current sensor?

In this tutorial, you will learn how to design alternating current measurement system using acs712 hall effect current sensor and Arduino Uno R3. But you can apply same concept to Arduino mega, pic microcontroller, 8051 microcontroller or avr microcontroller. you just need make change in code but the rest of the concept will remain same.

Can a light bulb be measured with acs712?

Tests will be done on an incandescent light bulb, controlled by a light dimmer in series with a reference multimeter and the ACS712 current sensor module. Here’s the plan:
