Light monitoring system faq

hi everyone ,

i have a question regarding the ,data that is being displayed on the bolt web .

it is like 1.02 thousand , what is the unit of that value

mean 1.02 thousand is volts or illuminance or some other thing ? .

Hello! chaitanyapudi, i too had the similar question,
but voltage cannot be 1.02k volt or 160V (my observation).
So, voltage across LDR must be calculated such that to give data in light intensity per area (lux or luminous flux) or just intesity (lumen).
And this data is uploaded on cloud.
Another thing that bothers me is, how do manufacturers of the module know that we will use only LDR on that A0 pin. And after all we didn’t write code to calculate the intensity.
Hence, the data we have seen must be 1.02 thousand miliVolt or something.
:wink:

on increasing intensity of light, resistance decreases. So 125 cannot be ohm.
