Hi guys,

Do you know any CMOS diy sensor (similar to this: https://es.aliexpress.com/item/32565099746.html) that allows a 30 sec exposure time?

Thanks in advance,

Cheers.

 

Anybody?

 

Hello,

Did you see the specs on the given page?



There is the "shutter" time given.

Yes, that cmos sensor dosn't have slow shutter speed, what i'm looking for is another one with slow shutter speed that can give me an exposure time of at least 30 sec.

Do you know any?

 

OK, it sounds like you are looking for an IMAGE sensor that can run in an integrating mode, probably for very low light applications. So either you are seeking a sensor for a very low light application, or else you need to explain what it is that you want to accomplish, because it is really not clear how you would use an image from a log exposure.

OK, that makes perfect sense then. And it limits the choices a bit because mostly cameras try for the shortest possible exposure times to catch fast motion. So really you indeed do need an image sensor, not a standard camera. It is entirely possible that you would be able to write new code for an existing camera, if the documentation about the hardware was available. That whole area is far beyond my skill set, so I am not able to help there. But here is an interesting option, which is to use a standard camera and do the storing one pixel at a time in an outside computer. Array processing of pixels is already done, and that might be a whole lot simpler since you would not need to do hardware designing.

 

And long exposure time can greatly increase the noise levels if I remember correctly.
Multiple exposure and post processing may work better.
