ACS712 Current Sensor 20A
$2.001pcs
The ACS712 current sensor measures electrical current based on the Hall effect. A magnetic field generated by the flowing current is detected by an internal Hall element and converted into a corresponding analog voltage signal. This signal enables current calculation and is useful for monitoring system operating status.

Description
The ACS712 Current Sensor is a sensor used to detect current. The principle is that when current flows through a conductor, the conductor generates a magnetic field. The Hall sensor inside the sensor detects the change in the magnetic field and generates a voltage proportional to the current. By outputting this analog signal and performing calculations, the current being detected can be determined. It is suitable for monitoring whether the system is operating normally.
ACS712 Current Sensor 20A
The parameters of the 20A version are basically the same as the 5A version, but the calculation formula has changed.
The formula is as follows:For forward NA current, Vout = VCC/2 + 0.1V * N, where N = (Vout – VCC/2) / 0.100.
