Use OV2640 camera on ESP32 board to measure light level (lux)

[irealanujuti]

I find myself with an ESP32 board with an OV2640 camera (a Firebeetle 2). My application is to build a lux Sensor to run motorized builds (which take commands from a WiFi hub) when an individual window is showing high lux (lower blinds) or low lux (raise blinds). I can definitely and obviously just solder on and use a photoresistor, but given that the camera is already there... I wondered if there was a practical way to use it to measure the rough light level. APKLUB

Any suggestions?

There might be a way, if you can turn off the autoexposure action.

Integrate a gray scale image, for example.
