I am using this is to sense the current of 1 hp motor, so that I can actuate another motor depending on this current.
Current drawing of the motor is 5 A, At starting it would be approx 15 A, Let's take it 20 A. Working of the Motor would be at 5. I need to start another small motor between 3.8...

When we Interface Rectifier plus to ADC then, as it comes from the CT won't it be fluctuating DC voltage. So how to set ref voltage for ADC. Means from 0to?? V it would be 0to5 V. So what would be input Ref voltage which would be converted to the Voltage. As I am connecting Rectifier from CT...
Hello Sir BigDog
I have utilized the AT89s52 previously. But now I want to detect current in the motor. So I have introduced CT but I can get analog output across resistance of CT so I need ADC.
If I go for AT89S52 then I need to take separate ADC which costlier than uC itself so better I go...
I need to give signal to another motor to actuate it, depending on the ampere taken by main motor.
So how to utilize the output of the CT... Can you please elaborate it in detail... Because what I am not having much knowledge of how to apply it...
Regards...

Thanks once...
Thanks Charu...
What I think is if I convert in to DC it cost much less. But ADC itself costs around Rs. 100. So I guess converting in DC would be good.
Another question I have is if I would be having the 230v, 4A current. Let Output of CT be 40 mA still AC... But what about voltage. Do I need...
First of all thanks for such a quick response.
I also need to control it with the AT89C52. so I need to give signal to it to inform uC(micro-controller) that the specified current has reached and so that uC can operate other things.
Is it possible to do so without Current Transformer.? Do I...
Hello,
I want to sense the motor load. what I want to do is I want to start and stop feeding depending on the load(Current) taken by motor.
For this I have searched various things and found the I to V converter an easy and chipper option to implement this.
Now issue is I am not able get where...
