Current sensor output monitoring logic

Using Arduino Sensors
1

Hi All,

Need your Guidance for developing a circuit which can continuously monitor my analog wave (which is output of a current sensor). it should monitor that wave in way that if the wave goes out with a tolerance of x amount (0.2 of the measuring unit) it can toggle an output pin as an indicator.

Any help/Guidance is highly appreciable.

Regards,
Nitin Verma

What is the frequency and amplitude of the wave? Is the wave AC (does the wave go negative with respect to ground)?

Please disclose full details of the current sensor and what determines being in tolerance (in numbers/units)
