ACS758 AC/DC 200A Current Sensor

/*
Here's an example code for interfacing two ACS758 AC/DC 200A current sensors with an Arduino:

This code initializes two ACS758 current sensors on analog pins A0 and A1. It reads the current values every second and prints them to the Serial Monitor.

Also, be sure to check your specific board and sensor specifications before using this code. Working with high currents can be dangerous; take all necessary precautions and safety measures while working with high-current circuits.

const float SENSOR_SENSITIVITY = 40.0; // Sensitivity of the ACS758 (40 mV per A for ACS758LCB-200)
