Dear all,
I am looking for current sensor that can measure 2A min current with better accuracy. I have tried with ACS712 5A rated from sparkfun both version . But i found inspite of using it has distortion . I tried to stablize using average and SD of sample. output . But it seems out is not stabilize. SO anyone can suggest me PCB mount current sensor with better accuracy .
I wanted to try with shunt basis model. But those are expensive costing me around 850RS(13$)
My specification as below
input to sensor IC: 0~5v
out put of sensor: analog 0~5v linear will be better
measuring range :2A~5A
PCB mount
accuracy:1%
Dear all.
I am planning to design Rshunt basis current measuring . My current measuring range is 1A~2A. I need analog output of 0~5v analog with 1% ACCURACY. Please help How can i do this.

I found conversion circuit here. Will it serve my application.
I tried with
But With these model i found accuracy is not good gives 5% error. output is not stable even load not connected. I tried with moving average and SD to filter . but distort more.
Kindly give your suggestions for building shunt basis current sensor module.
Dear AMPS-N, stop cross-posting.
sorry for that.
I am planning to use below sensor . I wanted to know how could i amplify the voltage to get analog output o~5v .

Or suggest me how can i use it. I seen lot people using below sensor. But they not posted schematic.
Is correct circuit or not
What is max output can be given to analog port.
I am planning to use WCS2052, Required document attached above
