What is current sensor ACS712?
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.
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.
Where are current sensors used?
They are used with both AC and DC current. Current sensors allow us to be able to measure current passively, without interrupting the circuit in any way. They are placed around the conductor that’s current we want to measure. Current transformers are essential in many applications.
How does the Hall sensor work in acs712?
A voltage proportional to the sensed magnetic field is generated by the Hall sensor, which is used to measure current. The proximity of the magnetic signal to the Hall sensor decides the accuracy of the device. Nearer the magnetic signal higher the accuracy. ACS712 Current Sensor is available as a small, surface mount SOIC8 package.

How does a Hall effect current sensor work?
Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer.
