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 5A
The ACS712 Current Sensor needs to avoid interference from other magnetic fields, such as power sources, magnetic metals, etc., during use. When using the 5A version, the output voltage analog signal needs to be converted into current using the following formula:
For forward NA current, Vout = VCC/2 + 0.185V * N N = (Vout – VCC/2) / 0.185
For reverse NA current, Vout output = VCC/2 – 0.185V * N N = -(Vout – VCC/2) / 0.185
For example, with the 5A range module and a forward 1A current, Vout = VCC/2 + 0.185V * 1

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.
