VD6283 Sensing problem with range?

MKash.3 · ‎2023-03-29

I have been using VD6283 with STM32 and have found that they work well in detecting flicker when the light source is near the sensor. However, I have encountered an issue where the flicker is not detected when I move away from the light source.

Additionally, the sensor does not detect flicker from room lighting.

I have another question: can this sensor detect a mixture of lights? For instance, if there are four lights in the room, will the sensor be able to detect all of them simultaneously? and what will be the flickering frequency whether it's a mix of frequencies?

Hello

Sorry for the late answer on this forum.

What is the configuration you are using in term of HW and SW for the flicker detect ?
What is the light level in lux ?

As we are doing a FFT you will get all the frequency component of the light. The GUI is showing only the main freq but using the driver you can plot your FFT and may extract all the other frequencies. It requires post processes.
