Due to current technological advances, the structure material for small and low cost sensors became theoretically and inexpensively practicable. Even though, Industrialization increase the degree of automation at the same time it increases the pollution by releasing the unwanted parameters in atmosphere especially in industrial areas.

So there should be a system to observe and assess the industrial pollution. Particular attention is given to factors which may affect human health and the health of the natural system itself.

Industrial monitor is the collection of information at different locations of industries and at regular intervals of time in order to provide the data which may be used to define current conditions. Due to the difficulty of parameter large variations are found between different industries.

Project Summary:

i. The main aim of industrial pollution monitoring system provides real time information about the level of air pollution in, as well as provides alerts in case of radical change in quality of air.

ii. This information can then be used by the authorities to take on time actions such as evacuating people or sending emergency response team.

iii. We can uses an air quality index to classify the various level of air pollution.  

iv. Air pollution is rising issue these days, it is compulsory to monitor air quality and keep it under control for healthier future and healthy living for all.

v. System uses air sensors to sense presence of injurious gases/compounds in the air and regular transmit data and report it to the online server over IOT.

vi. This allows to authorities to observe air pollution in different areas and take act again it.

Aim and objectives of project:

i. To create a tool this will monitor the quality of air of our atmosphere. Display the data on LCD.

ii. To build a robust system that can measure the industrial pollution and help to reduce it and to decrease human being interference in monitoring the industrial pollution to reduce pollution and provide a healthy environment for the workers to work in.

iii. To make the industrial pollution monitoring a wireless system. To protect the environment from industrial pollution.

iv. To build a robust system that evaluates the industrial pollution continuously and indicates when there is an increase in the emissions and takes action to control it using wireless technology that is IOT.

Brief literature review and Prior Art Search

Literature review

We are learnt from the literature review that transportable monitoring device can be designed and developed using solid state gas sensors and simultaneously information on the observed air pollution information can be disseminated in real time.

The concept of Internet of Things (IOT) is also emerging very fast where everything around us comes with an internet connectivity for monitoring and control. Monitoring the environmental

Parameters and initiating a control action from internet is also part of this concept. In our proposed work, we design an environment monitoring system, capable of monitoring and control of environmental parameters.

we focus on design of a low cost system that is capable of not only remotely monitoring the environment variables like temperature and industrial pollutants but also initiates some control action like switching devices ON/OFF from the internet.

Plan of Our Work:

• In first phase, we have looked after and studied the patents and research papers for  the project. We made different Canvas which includes Ideation Canvas, Empathy Canvas, Product Development and AEIOU Summary for better  understanding and development of our project and making it efficient and public friendly.

• In the remaining other phase, we would like to move forward with Hardware Implementation interfacing it with software algorithm.

Air quality sensor is for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. Ideal for use in office or factory with simple drive and monitoring circuit.



A carbon monoxide detector for the Arduino-based DIY security system. The carbon monoxide detector is a semiconductor gas sensor tuned to detect carbon monoxide. It is in the same family of devices as the smoke detector sensor, measuring the change in surface conductivity of tin dioxide in the presence of carbon monoxide. This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance.



This sensor module utilizes an MQ-6 as the sensitive component and has a protection resistor and an adjustable resistor on board. The MQ-6 gas sensor is highly sensitive to LPG, iso-butane, and propane and less sensitive to alcohol, cooking fume and cigarette smoke. It could be used in gas leakage detecting equipments in Domestic and Industrial applications. The resistance of the

Sensitive component changes as the concentration of the target gas changes.



The MQ5 is used in gas leakage detecting equipments in consumer and industrial applications, this sensor is suitable for detecting LPG, natural gas and coal gas. The sensitivity can be adjusted by using the potentiometer.



Sensitive material of MQ-4 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist the sensors conductivity increases higher along with the gas concentration rising. MQ-4 gas sensor has high sensitivity to Natural gas, Methane and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, it’s low cost and suitable for different application.



The analog gas sensor – MQ2 is used in gas leakage detecting equipments in consumer and industry markets, this sensor is suitable for detecting LPG, i-butane, Propane, Methane , Alcohol, Hydrogen and Smoke. It has a high sensitivity and fast response time and the sensitivity can be adjusted using the potentiometer.

Wi-Fi module:

ESP8266 serial ESP-01 WIFI Wireless Transceiver Module  

ESP-01 ESP-8266 is an ideal choice for hobbyist to start experimenting with IoT. The dimension of this module is 25mm x 15mm, with simple pin connections (standard 2×4 pin headers), using serial TX/RX to send and receive Ethernet buffers, and similarly, using serial commands to query and change configurations of the Wi-Fi module.

 ESP8266 ESP-01 Serial WIFI Transceiver Module is a cheap and easy way to connect to internet via WIFI to any microcontroller platforms like Arduino. You can use AT commands to connect to Wi-Fi networks and open TCP/IP connections(without need to have TCP/IP stack running in microcontroller).

 The module(ESP-01) can work with AT command when used with Arduino, USB to TTL adaptor (FTDI USB module is recommended). Additional power supply might be needed to power up the board. With GCC too chain and an SDK availability opportunity with ESP8266 as an IOT device is endless.

AEIOU Summary

 Activities are goal-directed sets of actions—paths towards things people want to accomplish. What are the modes people work in, and the specific activities and processes they go through? In activity framework, there are two blocks. One block is General impression/Observation and second is Element, Features and special notes. This block says that which activity are performed in domain

 Environments: This includes that particular area where activities take place. The character and function of the space, of each individual's spaces, and of shared spaces.

 Interactions: This includes interactions between a person and someone or something else; they are the building blocks of activities. About the nature of routine and interactions between people, between people and objects in their environment.

 Objects: These are building blocks of the environment, key elements sometimes put to complex uses (thus changing their function, meaning and context). What are the objects and devices people have in their environments and how do they relate to their activities.

 Users: Those people whose behaviors, preferences, and needs are being observed. Who are they? What are their roles and relationships? What are their values?
