the main reason for this is the illumination. if you place your ldr in contact with your hight intensity beams like phone led’s etc. obviously we do the project inside the house so we don’t get chance of any other light source. you can check this by covering your ldr with your hands the value changes. so when hight intensity light comes in close contact with the ldr it shows 1.02 thousand. again don’t panic the solution is easy as sipping the coffee.
it is the highest value that can be measured by the boltiot device ,it has some limitations as well.
yes, of course that’s what I’m coming to say with prior explanation of why it is. some new one may get panic whether there is a problem in their connections or ldr itself. so I said clearly in that case.
