INTERNSHIP TOPIC
Developing An Embedded IOT Light Monitoring System
A Node MCU is a development board that uses ESP8266 Wi fi module to enable IOT capabilities.
The project demonstrated the ability to integrate embedded systems and IoT technologies to solve real-world
problems, such as optimizing lighting systems for energy management, enhancing plant growth, or improving
occupant comfort.
A light monitoring system is a system that tracks and monitors the amount of light present in a particular environment
or space.
It uses LDR sensor to detect the ambient light intensity and sends the data to the Node MCU board.
A light monitoring system can provide a valuable insights into light levels in a given environment ,allowing for better
management and control of lighting system for various application.

TASK PERFORMED
SOFTWARE
 Arduino IDE : This is an open-source integrated development environment (IDE) that is used to
program the Node MCU board. It can be downloaded from the official Arduino website.
 MQTT Broker: A broker is a central hub that manages the communication between the NodeMCU
board and the other devices that are subscribed to the same topic.
 MQTT Client: An MQTT client is a software program that connects to the broker and subscribes to a
topic to receive data.
 Libraries: To program the Node MCU board, you will need to install the following libraries in the
Arduino IDE
 ESP8266 WiFi : Used to connect the Node MCU board to the wifi network
 PubSubClient : used to implement the MQTT protocol on Node MCU board

RESULTS
The system consists of a light sensor, a NodeMCU board, and an MQTT broker, which work together to collect
and transmit real-time data to other devices for analysis. The system was tested in a laboratory environment under
different lighting conditions. The system was able to accurately monitor light levels and transmit data in real-time
to the MQTT broker. The data was then analyzed using a software application, which provided useful insights on
the light levels in the environment. The software application displayed the real-time data in graphical form, which
made it easy to identify any changes in the light levels.

CONCLUSION
The light monitoring system using Node MCU and MQTT provides a cost-effective and
efficient solution for monitoring light levels in a particular environment. The system
consists of a light sensor, a Node MCU board, and an MQTT broker, which work together
to collect and transmit real-time data to other devices for analysis. The system was
evaluated based on its performance and ability to provide real-time data analysis for
various applications. The light monitoring system using Node MCU and MQTT has the
potential to revolutionize the way we monitor and optimize lighting systems in various
environments.
