How do I connect my ACS712 current sensor?

Circuit Design The screw terminals of the ASC712 Current Sensor Module board are connected in series with the motor and power supply as shown in the circuit diagram. Then connect the VCC, GND and OUT of the ASC712 board to +5V, GND and A0 of Arduino.

How do you connect a Hall effect current sensor to Arduino?

The VCC and GND pins of the Hall Effect IC i.e. Pins 1 and 2 from the branding face are connected to +5V and GND of Arduino. The OUT pin of the Hall Effect IC is pulled HIGH using a 10KΩ Resistor. Whenever the magnetic field is placed near the Hall Effect IC, the output of the Hall Effect IC becomes LOW.

What is ACS712 current sensor?

The ACS712 is a fully integrated, hall effect-based linear current sensor with 2.1kVRMS voltage isolation and a integrated low-resistance current conductor. Technical terms aside, it’s simply put forth as a current sensor that uses its conductor to calculate and measure the amount of current applied.

Can ACS712 measure DC current?

ACS712 is a Hall Effect-Based Linear Current Sensor it can measure both DC(Direct Current) and AC(Alternating Current).

Can ACS712 measure voltage?

ACS712 is a current sensor that can operate on both AC and DC. The output of this current sensor is analog, so to read it, we can directly measure the output voltage using voltmeter or measure it by using a microcontroller like Arduino through Analog Read pin or ADC pin.

What is Hall effect current sensor?

A hall effect current sensor allows non-contact detection of direct and alternating currents, using a hall element, a magnet-electric converting element. This minimizes power loss of the target current circuit and has a simple structure with high reliability.

Can ACS712 measure AC current?

The ACS712 measures current in two directions. We are measuring AC current of 50Hz i.e. 20mSec per cycle and we get around 4000 Samples in one cycle. With both peaks known, it is a matter of knowing the shape of the waveform to calculate the current.

How does ACS712 measure DC current?

About Acs712 Pin out and Pin description of the chip is below. Connect the sensor in series to the system whose current you want to measure. Cut the circuit wire and connect one end of wire to IP+ and other to IP-. Recall the high school lectures, current can be measured only in series.
