I’ve done the 1st IOT project on 19th and then disconnected the device. And today after I connected the device again in my room under the same light the readings for the light is coming very low. Wondering about what can be the reason behind !

Check if the sensor is obstructed by something if not try using a flashlight at it and see if it gives 1.02k as the reading .
Since this is a very low reading try to redo the connections and check if the code is correct.
Check the connection is proper and it’s not open or short circuit.
That might make big difference in readings.
Check the jumper wire you are using is working perfect.
ldr was loosly connected. Getting normal values again after fixing that. Thanks:)
