Parking System 
In the proposal, [8] the creator work with car parking 
system using Node MCU, IR sensor, LED. This system 
helps in arranging the parking slot and encourages the driver 
to achieve their parking spaces effectively as they realized 
which space is empty. The parking spot can be recognized 
using an Infrared sensor that interfaces with the ESP12-E 
(Node MCU) module that was programmed through the 
Arduino IDE. Users can get to parking spot data using a cell 
phone by means of an application. Particularly for users 
who have been enlisted previously, they have a code for 
login the application as the necessity for security system and 
user parking suitable [Fig. 5]. The system can work with the 
goal of research properly. In the system, the IR sensor is 
used for identifying the parking spot. The IR sensor is 
attached with the microcontroller Node MCU. Node MCU 
acts like a middle road between the sensors and the cloud. 
The Node MCU then transmits this information to the 
Firebase through Arduino IDE. The mobile application acts 
as an interface for the users to collaborate with the system 
on Cloud Firebase. This publication is helping us to work 
with IR sensor and Node MCU, firebase and the cloud 
server associated with the web it may be controlled 
remotely from anyplace on the world. 
Fig. 5. Car entering the parking area and the display shows the number of 
vacancies in the parking slot. 
This publication is related to the projects that can help us 
to work with IR sensor and Node MCU and applications 
that work with the cloud server. 
These journals are related to our projects. It helped us to 
build the system and gave support to our theoretical 
knowledge so that we could work with IR sensor and Node 
MCU. Moreover, we tried to learn more about different 
apps that bridges between with cloud server and the Node 
MCU. These topics gave us an abstract idea that how 
actually a system can be implemented for border system, 
security purposes, using Infrared sensor in parking systems 
and ultrasonic sensors for distance calculation etc.

Theorem 1 
Here we have come through a plan diagram to get rid of 
the problem. Our basic idea is illustrated over the system 
flow diagram in Fig. 6. Here the diagram clearly states the 
flow of the system. Initially in the system the IR sensor 
detects the change and gives the signal to Node MCU. 
When the Node MCU receives the signal it sends to the 
BLYNK cloud and over there the data is processed and 
passed to the android app. From the app the notification is 
received and the buzzer and light is turned on.

Methodology Description and Its Functions 
For building up the project of the system proposed, we 
are working with Node MCU esp32. Node MCU is an open 
source IoT stage. It includes firmware which keeps running 
on the ESP32 Wi-Fi SoC from Espressif Systems and 
equipment which depends on the ESP-12 module. Node 
MCU esp32 Wi-Fi module is working with an infrared 
sensor (IR). The location scope of the IR sensor is around 2 
cm to 30 cm. The sensor module is interfaced with Arduino 
having IO voltage level of 3.3V to 5V. Most Importantly, if 
an object detects by the IR sensor and after that the signal 
pass to the Node MCU esp8266 Wi-Fi module. Node M CU 
will check whether the Wi-Fi is connected or not. From that 
point forward, Node MCU esp8266 Wi-Fi module will 
check the signal from the IR sensor. And after that, the 
Node MCU esp8266 Wi-Fi module analysis the signal 
through Arduino IDE and send an HTTP request to the 
BLYNK cloud server. At the point when the user needs to 
see the touch history, then the web sends a request to the 
cloud server. Cloud server synchronizes the data from the 
database and response to the web server. At long last, the 
user can see details of the object which cross the IR sensor. 
Let’s say when an intruder arrives near the border and 
finds out that there is no soldier near the border or no 
security is there. He or she is trying to enter the border area 
illegally by taking the advantage of the current condition. 
The intruder steps in and blocks the signal transmission of 
the device. Then immediately alarm notification will be sent 
to the nearby army soldier. The soldier will be notified and 
will move towards the place where the intruder is. And can 
warn the intruder and take proper action that is needed to be 
done for breaking the law. Symbolic representation is 
shown in Fig. 7.
