Re: YHDC current sensor - the theory please

adjust resister to for the mid current used incase of some nonlinearity... shotkey diode has .3 volt drop

Re: YHDC current sensor - the theory please

You might want to specify the model number of the sensor since there are a number of different types, and the circuit shown may not even apply

Re: YHDC current sensor - the theory please

Have you connected your CT as shown in your first post? That is, the bottom to 2.5V (or VRef/2) and the top to input pin AND - VERY IMPORTANT - a load resistor shown as 33ohms in diagram? You must...

Re: YHDC current sensor - the theory please

It can't work wired the way you described. The ac signal must be biased by vcc/2 and be less than vcc peak to peak.
If the serial baud rate is too low it will ruin the sample rate.
If the burden...

YHDC current sensor - the theory please

Richard,

I've connected my YHDC sensor one pin to ground and the other to RA5. Got readings (see hereunder).

Because I'm not sure what I'm doing right now with the current sensor, I tried to...

YHDC current sensor - the theory please

...sorry Richard, didn't try your code by now - still in office.... 😬

Re: YHDC current sensor - the theory please

Why do want a nasty old analogue peak detector, When you can create a digital one as per my code ?
Using the very cct you posted.
If you realy need to try analogue google ""peak detector circuit"...

Re: YHDC current sensor - the theory please

May I kindly ask for a principle circuit to start with the correct foot please?

I don't see how to "rectify" a very low AC signal - I'm an electrician and used to easely handle voltages over...

Re: YHDC current sensor - the theory please

my dev board has a 3.3v reg, otherwise can't see that it makes a difference

not really , it needs a rectifier too. if the wave is not symmetrical the neg and pos peaks may be needed. plus...

YHDC current sensor - the theory please

Peak detector! That's it!

Thanks a lot for explaining and the code I can't wait to try when I'm back from office :biggrin:

Though, why do I always read about 3.3V measuring circuits and not 5V?...
