The Table 1 depicts a comprehensive detail of the entire reference values that can be used for detection of vehicle
using LDR sensor with threshold reference values at different time intervals. It can be noticed that, there are different
threshold values for different time intervals. In order to the detect vehicle in the parking slot from 8:00 AM to 5:00 PM, there is single threshold range. However the from 5:00 PM to 7:30 PM, there are 4 different threshold ranges.
Therefore, for each time interval there will be different threshold range value for proper detection of the vehicle.
