The working of an LDR is based on photoconductivity principle.
When the light is absorbed by the material then the conductivity of the material reduces.
Now using the LDR, we can actually measure the intensity of light upto a desired range of area.
Here, LDR increases it's resistance in the darker region and vice versa.
Based on this, we connect and send to the Bolt iot cloud and utilize the data for further purposes!
circuit connection for light intensity monitoring system
To the Bolt Iot wifi module,connect the ldr(one end to the 3v3 and the other to A0).
Now connect 10k resistor(one end to GND and other to the A0)
Before connecting it with the usb cable,make sure that the components do not touch each other(other wise it leads to short circuit).
