Current Sensor ACS712 30A

The ACS712-30A current sensor is a commonly used current sensor with a 30A nominal current rating. It is not a module itself but rather the maximum current rating of the ACS712 series that can be used to measure currents up to 30A.

It operates similarly to other ACS712 modules, employing the Hall effect to sense the magnetic field generated by the current flowing through a conductor and converting it into a voltage output. The output voltage will have a sensitivity of 66mV per ampere of current.

To integrate the module into your circuit, you will need to properly connect the sensor to the circuit being measured and supply power (typically 5V) to the sensor. The output voltage can be read using an analog input of a microcontroller or other data acquisition system, and the current value can be calculated by scaling the output voltage with the appropriate factor.

The module is commonly used in applications where higher current measurements are required, such as industrial machinery, motor control systems, power distribution systems, and other applications involving currents up to 30A.
