The literature presented above propose different WSN based parking systems that can be used for detecting vehicles
however, there are many factors and aspects that needs to be considered. Factors such as, precision in vacant parking
detection and vehicle detection under different non-target elements such as living things (humans or animals) or other
than vehicle objects. Also location of the parking system such as, indoor or outdoor, as the visibility plays an important
role for some sensors. Similarly, the environmental conditions like weather (cloudy or dusty) can also impair the
performance of the sensors and lead to false detection. Therefore, keep such factors and aspects in consideration, the
existing literature lacks in such considerations which makes the precision of different sensors ambiguous and can lead
to false detection. This research paper presents performance of LDR sensor with IR sensor and gives the comparative
analysis in terms of their accuracy and reliability under different environmental conditions.
