Parking in congested places frequently leads to major issues like air pollution, traffic jams, etc. This paper presents a prototype for an Internet of Things (IoT) based central car parking management system that attempts to minimize car parking problems. The proposed system is relatively low-cost, scalable and consumes less power compared to other parking systems. This system uses Arduino microcontroller-based TCRT5000 infrared sensors to detect vehicles in the parking spaces. XBee peripheral modules are located in different parking lots at different locations to transmit the sensed data to XBee central module that is placed close to the parking lots. The central node then updates all data to the Blynk IoT platform via Wi-Fi wireless technology present in the NodeMCU board. The availability of parking lots can be viewed using a smartphone through Blynk application.
