INTRODUCTION

The Internet of Things (IoT) refers to a network of interrelated physical devices embedded

with sensors, software, and network connectivity that enable these objects to collect and

exchange data over the Internet . By bridging the physical and digital worlds, IoT

technology allows for real-time monitoring, control, and data analysis of environments and

systems which were previously isolated or manually managed. In recent years, IoT has

become a cornerstone of modern technology solutions, finding applications in smart

homes, healthcare, industrial automation, environmental monitoring, and many other

fields.

Sensors are the fundamental components of IoT systems. An IoT sensor is a device that

detects changes in an environment (such as temperature,

distance, etc.) and converts them into data that can be analyzed and acted upon . These

sensors, when connected through microcontrollers and communication networks, enable

remote monitoring and decision- making without direct human intervention. For example,

temperature and humidity sensors can monitor climate conditions in a room, motion

sensors can detect the presence of people, and gas sensors can raise alerts for smoke or

harmful gases. The data from such sensors can be transmitted over the internet to cloud

platforms where it is stored, visualized, and used to trigger automated responses or

notifications.

This internship specifically focused on “IoT Using Sensors”, aligning with the above

concepts. The goal was to train me in integrating common sensors with microcontroller

platforms (Arduino and NodeMCU) and to connect these sensor-equipped devices to the

internet for data transmission and remote monitoring. Key learning outcomes included
4
understanding sensor theory (how each sensor works), practical sensor interfacing (wiring

and programming), microcontroller programming in Arduino IDE, using communication

protocols (HTTP and MQTT) to send data to cloud services, and creating real-time

dashboards using IoT platforms like ThingSpeak and Blynk. Another important aspect was

learning troubleshooting techniques for hardware and network issues, which is crucial for

real-world IoT deployments.

By the end of the internship, I built a mini IoT project that integrates multiple sensors to

monitor environmental conditions and security parameters, sends the collected data to the

cloud, and provides a user with real-time insights via online dashboards and a mobile app.

This report will detail each step of that journey, illustrating how theoretical knowledge was

applied in practice each day.

SYSTEM STUDY

EXISTING SYSTEM

Traditionally, monitoring environmental conditions or safety parameters (like temperature,

humidity, smoke, etc.) might involve standalone devices or manual checks. For example, a

home might have an analog thermometer, standalone smoke detectors, or a security system

that sounds an alarm locally if motion is detected. These systems often work in isolation

and are not connected to the internet. Data from them is not logged over time – one has to

be physically present to note a reading or hear an alarm. In case of an event (like a gas leak

or intruder alert), only an on-site alarm might trigger, and if no one is present, the warning

could go unnoticed. Additionally, manual record-keeping or periodic human observation

leads to gaps in data and delayed responses.

Figure 3.1.1: Traditional Monitoring

Proposed System (IoT-based Monitoring): The IoT-based system developed in this project

addresses the limitations of traditional monitoring by leveraging internet connectivity and

cloud computing: - Real-time Remote Monitoring: Sensor data (temperature, humidity,

motion status, gas levels, etc.) is continuously collected and sent to cloud servers.
16

Authorized users can remotely monitor these live readings from anywhere via a web

dashboard or mobile app. This eliminates the need for physical presence – for instance, one

can check their home’s conditions while at work or traveling. - Data Logging and

Analysis: Unlike manual monitoring, IoT sensors provide continuous streams of data,

enabling thorough and detailed information gathering . The system logs data over time on

ThingSpeak, allowing analysis of trends (e.g., how temperature fluctuates daily) and

automated alerts if abnormal patterns are detected. This historical data can be used for

insights and improving decision- making. - Instant Alerts and Notifications: The proposed

system can instantly notify users of critical events. For example, if smoke is detected above

a threshold or if unexpected motion is sensed, the system (through Blynk or ThingSpeak’s

alert triggers) can send an immediate push notification or email/ SMS to the user. This

enables prompt response to incidents, improving safety and potentially preventing damage.

In essence, IoT enables proactive rather than reactive maintenance – issues can be caught

in real-time rather than after the fact. - Integration and Automation: Multiple sensors are

integrated into one cohesive system. The data from different sensors can be correlated and
17
used to trigger automated actions. For instance, if high temperature and smoke are detected

together, an automated warning can be escalated as it indicates a fire risk. Or if motion is

detected while the homeowner is away (detected via a schedule or a remote arm/disarm in

the app), the system could trigger an alarm and notify security services. Automation rules

can be implemented on the cloud or edge (device) side to create a smart environment. -

1
1
Accessibility and User Interface: The IoT system provides user-friendly interfaces (the

Blynk mobile dashboard and ThingSpeak charts) to view data and control the system. This

means even non-technical users can easily interpret sensor readings (via visual gauges or

graphs) and interact with the system (e.g., pressing a button on the app to turn off an alarm

or reset a sensor). No specialized equipment is needed to view the data – any smartphone

or computer with internet access suffices. - Cost and Efficiency: While the initial setup of

IoT devices is an investment, it reduces the manpower and maintenance costs in the long

run. There is no need for frequent manual inspections (which might require personnel or

travel to remote sites) . The system can cover multiple parameters simultaneously and

provide a centralized monitoring capability which is more efficient and reliable than

scattered independent devices.

DATA FLOW

The data flow of a delivery challan begins with its creation by the seller or supplier upon

the readiness of goods for shipment. This document serves as proof of delivery and

includes essential details such as the challan number, date, sender's and receiver's

information, description of goods, transport details, and signatures of authorized personnel.

After creation, the challan accompanies the goods during dispatch, ensuring proper

packaging, loading onto transport vehicles, and recording of dispatch details. During

transit, it facilitates checkpoints and inspections for verification. Upon delivery, the

receiver verifies the goods against the challan, signs it to acknowledge receipt, and returns

a copy to the sender for documentation and archiving. Post- delivery, the challan aids in

updating inventory, generating invoices, and resolving disputes if any discrepancies arise.

Finally, the challan is archived for auditing purposes, maintaining a comprehensive record

of transactions.

3

6
The data flow of a credit notes initiates with its issuance by a seller or supplier to a buyer,

prompted by reasons such as goods returned, overcharges, or billing discrepancies. This

document specifies critical information such as the credit note number, issuance date,

detailed reasons for its issuance, and pertinent transaction particulars. Once generated, the

credit note is promptly transmitted to the buyer for verification. During this stage, the

buyer reviews the details provided and either validates the credit note or raises disputes

where discrepancies are identified. Validated credit notes are then applied to the buyer's

account to rectify outstanding balances or offset future invoices, ensuring financial

accuracy and reconciliation. In cases where disputes arise, disputed credit notes undergo a

rigorous investigation process to identify and resolve discrepancies effectively. This

investigation involves comprehensive scrutiny of transaction records, communication with

relevant parties, and clarification of any misunderstandings or errors.

The data flow of an expense commences with its initial occurrence and the meticulous

recording of pertinent details by employee or authorized personnel. These details typically

encompass the date of the expense, the amount incurred, the purpose behind the

expenditure, and the specific category to which it belongs. Once these details are recorded,

expenses undergo a structured approval process, adhering closely to organizational policies

and guidelines. This meticulous review ensures that each expense is valid, justifiable, and

compliant with established protocols.

Following approval, validated expenses proceed to the next phase where reimbursements

are processed for employees or payments are initiated for vendors. This timely

disbursement of funds supports efficient financial transactions, contributing to operational

fluidity and stakeholder satisfaction. Concurrently, the data from these expenses is

diligently entered into accounting systems, which serve as a critical component for

ongoing tracking and reporting activities. This systematic integration into financial records

plays a pivotal role in maintaining accuracy and completeness in financial reporting and

analysis.

3

The data flow of a recurring expense begins with its configuration in financial systems by

authorized personnel, who input essential details such as the amount, frequency, start date,

and duration of the expense to ensure regular processing. This setup ensures that the

expense is automatically generated and processed according to the defined schedule,

minimizing the need for manual intervention and ensuring consistent financial obligations

are met.

Once generated, recurring expenses undergo a thorough review and approval process based

on established protocols, which helps maintain stringent financial controls and ensures

compliance with organizational policies. Approved recurring expenses are then paid or

deducted from accounts as scheduled, with provisions made for any necessary adjustments

or cancellations to facilitate accurate financial planning and management.

The recurring expense cycle persists until the scheduled recurrence ends or is modified,

providing continuity in cash flow management and supporting reliable budget forecasting.

This structured approach not only streamlines financial operations but also enhances

efficiency and transparency in managing ongoing financial commitments within the

organization.

The data flow of a project encompasses several phases from initiation to closure, each

contributing to its successful execution. It begins with thorough project planning, where

objectives, scope, deliverables, timelines, and resource allocation are defined to establish a

clear path forward. This initial phase sets the foundation for effective project management

and ensures alignment with organizational goals.

During the execution phase, project activities are meticulously monitored, tasks are

assigned to team members, and progress is tracked to achieve predefined milestones and

goals. Regular status updates and communication among stakeholders maintain project

momentum and ensure that any deviations from the plan are promptly addressed, thereby

fostering collaboration and maintaining accountability across the project team.

As the project approaches its conclusion, final deliverables undergo rigorous review,

testing, and approval processes to ensure they meet quality standards and adhere to project

specifications

The data flow of a timesheet begins with employees creating detailed records of their work

hours and activities, typically including dates, hours worked, project or task codes, and

activity descriptions. This initial step is crucial for accurately capturing and documenting

time spent on various tasks or projects within the organization.

Once completed, timesheets undergo a review and approval process by supervisors or

project managers. This validation ensures that the recorded work hours and activities align

with project requirements and organizational policies, facilitating accurate payroll

processing and project costing. Approved timesheets are then processed for payroll

disbursement or client billing, supporting timely financial transactions and ensuring that

resources are appropriately accounted for.

During the approval phase, any discrepancies or issues identified are promptly addressed

through resolution and adjustment mechanisms. This includes correcting errors in time

entries or addressing inconsistencies to maintain data integrity and compliance with

internal policies and external regulations.
