hai ALL,


presently am designing power monitoring system project.
In that am using ACS756 IC(hall effect current sensor IC). it gives sinusoidal output corresponding to the load(normal -1.6 DC in multimeter)
when i trying to interface it with ADC of my controller, i try to catch the peak voltage of ADC for corresponding loads.but the out put is not stable.i think i have to follow some steps to measure the current.
could u suggest me some solution how measure the current from ACS 756?thanks for your support.


regards,
karthikeyan

How did you get this idea...

ACS756 gives an analog output proportional to the current is is measuring and not a sinusoidal signal. Please read through : **broken link removed**
