I. DEVELOP THE IOT APPLICATION
1. Architecture
Figure 1 : System architecture
2. Components
NodeMCU ESP8266: NodeMCU is an open-source platform built on the ESP8266 that allows things to be connected and data to be transferred over Wi-Fi. Additionally, by including some of the most crucial microcontroller capabilities, such as GPIO, PWM, ADC, and others
Servo Motor: A small machine with an output shaft is called a servo motor. Sending the servo a coded signal allows for precise angular positioning of this shaft. The servo will keep the shaft in its current angular position so long as the coded signal is present on the input line. The angular location of the shaft varies if the coded signal changes. In real life, radio-controlled airplanes employ servos to position control surfaces like the elevators and rudders. Additionally, they are utilized in robotics, puppets, and radio-controlled autos. Figure 4 : Servo motor Breadboard: A breadboard is made of a plastic block that is home to a grid of electrical sockets with dimensions appropriate for retaining component wires, thin connecting wire, or the pins of transistors and integrated circuits (ICs). Inside the board, the sockets are connected in rows of five sockets.

- Tools and platform Arduino IDE: In addition to a text editor for writing code, a message area, a text console, a toolbar with buttons for frequently used operations, and a number of menus, the Arduino Integrated Development Environment, sometimes known as the Arduino Software (IDE), is also available. It establishes a connection with the Arduino hardware and communicates with it to upload programs. Figure 6 : Arduino Blynk: Blynk is an Internet-of-Things platform for iOS or Android smartphones that allows users to remotely operate devices like Arduino, Raspberry Pi, and NodeMCU. Using this application, you can compile and provide the right address on the various widgets to construct a graphical interface or human machine interface (HMI).

III. TEST AND EVALUATE
- I will upload the code and start compiling Figure 10 : Uploading and compiling
- Blynk display the information of temperature and humidity in the environment Figure 11 : User interface on Blynk
- Data is also stored on Google Firebase Figure 12 : Humidity data on firebase Figure 13 : Temperature data on firebase
Figure 15 : Result of feedback
- Based on the feedbacks, we can see that our system is pretty well-developed. As the opinions given from the customer, in the future, we will add the measuring UV features into the system to that it can satisfy the user requirements
