This document presents a design for an IoT-based smart parking system using NodeMCU ESP8266. The system uses ultrasonic sensors to detect parking availability, IR sensors at the entry and exit gates, and servo motors to open and close the gates. The ESP8266 controls the system and sends parking data to Google Firebase for online monitoring of availability from anywhere. When a car arrives, the IR sensors detect it and open the gate if a spot is available, as determined by the ultrasonic sensor.

3. ABSTRACT
• Now days finding parking in busy areas is very hard and
there is no system to get the details of parking
availability online.
• Imagine if you can get the parking slot availability
information on your phone and you don’t have roaming
around to check the availability. This problem can be
solved by the IoT based smart parking system.
• Using the IoT based parking system you can easily
access the parking slot availability over the internet. This
system can completely automate the car parking system.
From your entry to the payment and exit all can be done
automatically.

7. WORKING
• .Here the ESP8266 will control the complete process and
also send the parking availability information to Google
Firebase so that it can be monitored from anywhere in the
world over the internet.
• Two IR sensors are used at entry and exit gate to detect the
presence of car and automatically open or close the gate.
• Two servos will act as entry and exit gate and they rotate to
open or close the gate.
• Finally an Ultrasonic sensor is used to detect if the parking
slot is available or occupied and send the data to ESP8266
accordingly.
