Thanks kk99. Finally got a sensor! Now I just need to figure out how to get the board out of the case.

II am in Australia and finding it difficult to source the TSL250R ic. Is there an alternative that would be suitable please?

Cool project! It functions very well.

What's the ESP module? I've not seen one with that connector and LiPo capability.

I have added option to calculate the percentage flicker. In attachment there is updated source code.

A very interesting and useful project. I have often thought it would be good to be able to measure the actual flicker in lighting. This is eomthing I might have to come back to and try myself, sometime.

Awesome project. I worked in the lighting industry for a while and we did a lot of testing on our Zigbee mesh light controllers (and the attached luminaries, with their own driver/controller) to measure their response time to command inputs to the mesh. We used some high speed cameras to capture the light responses to on/off commands. All throughout the project, I kept thinking this would be a nice project for a Raspberry Pi (or similar platform) with an attached camera.

Interesting project and works really well. I never really thought of LEDs have any flicker to their light output.

Kind regards.

Very nice project.

What would it show for a fluorescent bulb?
