Have you ever heard on the radio or seen the news about poor air quality? Yes, you might be right! Many of us hear and watch the news on TV, mobile devices, or laptops regarding how air pollution impacts human health and the environment. You all might be wondering why I am discussing the topic of air quality, right? Additionally, Every few weeks, you find that poor air quality has made it to the headlines, only to fade from the recesses of public memory in a matter of days. For instance, there were reports of poor air quality in the first few days of 2024 alone.

One of the main risks to public health is poor air quality. In one year, home air pollution and ambient, or outside, air pollution combined result in 6.7 million premature deaths. A recent World Heart Federation report identifies air pollution as “the greatest single environmental health risk,” attributing 70% of air pollution-related deaths to it.

In India, the significance of air quality monitoring has increased recently as worries about pollution and its effects on public health have grown. Consequently, many manufacturers have developed advanced air quality monitoring devices to deliver accurate, real-time data.

In this blog, we will discuss the air quality manufacturers in India and how Oizom is leading in air quality monitoring, offering accurate real-time data using sensor-based technologies.

Leading Manufacturers in India

In India, numerous manufacturers of air quality monitoring systems are present. These systems include manual air quality monitoring, which generally includes a High-Volume Sampler System or manual sampler that draws a known volume of air through the filter. On the other hand, CAAQMS is the advanced version of AAQMS. It uses high-end technology like IoT for automated data collection and its transfer and analytics at the central server. The data transfer to the server is in real-time, and its interval is adjustable between 2-30 min. At the center, the data is analyzed automatically with advanced AI and archived or used accordingly.

Software Solutions

1. Envizom

One of the most significant measures in reducing air pollution in industry, construction sites, smart cities, smart campuses, mines, and quarrying is to install an AQM, which can correctly detect multiple air pollutants in real time. With effective AQMs in place, there is no need for guesswork about dust levels, smoke, and pollutants in the air. Oizom offers an end-to-end, scalable solution for real-time air quality monitoring and advanced data analytics to help industries and authorities pinpoint emission sources. It has numerous benefits, which I’ll discuss in the blog, and also discuss how Oizom achieved its data accuracy in air quality monitoring

Data accuracy (MSPCB)

One of the most critical stages in mitigating/reducing air pollution is having an AQM capable of reliably detecting numerous factors. Instead of guessing the smoke and dust levels, it can provide governmental bodies with an objective estimate of air pollution levels. This article will share how Oizom achieved data accuracy via collocating research studies.

Collocation study of Polludrone & a reference CAAQMS (Maharashtra Pollution Control Board)

• The collocation study was conducted between Oizom’s Polludrone and the Continuous Ambient Air Quality Monitoring (CAAQM) Station of Maharashtra Pollution Control Board (MPCB) at Bandra, Mumbai. This study aimed to validate the sensor-based air-quality monitoring system with internationally approved FRM (Federal Reference Methods) systems.
• With an impressive R2 of more than 0.9 with CAAQM’s FRM, Polludrone proves its reliability in Mumbai’s tropical/coastal climate and can accurately monitor air pollution, even at lower concentrations.
• This performance meets the recommended precision and accuracy error metrics from the US EPA Air Sensor Guidebook for personal exposure (Tier III: Supplemental monitoring and Tier IV: Personal Exposure) monitoring.

Cost-effective

• While safety should never be compromised, budgetary constraints are real. Balancing the necessity for accuracy, responsiveness, and other qualities against available funds might help to guide the decision. However, always favor critical features over price.
• Low-cost sensors are valuable for establishing sensor networks because they are more affordable in terms of buying and operations costs, flexible in deployment, and scalable. They can also potentially complement reference-grade monitors in the region with more data points.
• Oizom’s air quality monitoring devices are reliable and accurate, providing a more cost-effective alternative to existing reference stations, unlike expensive reference stations, which can hinder implementation due to their high cost and occupancy. Oizom’s technology offers a financially practical solution while maintaining performance. This low cost enables more deployment, resulting in more thorough air quality data collecting and proactive environmental management. With Oizom, communities can now afford to monitor air quality effectively, achieving the goals of a healthier environment in smart cities, industries, construction sites, and so on.

Collocating each device with USEPA-designated FEM reference grade analyzers

To achieve optimum data accuracy and empower industries and smart cities with accurate air quality monitoring, each Oizom device is calibrated as per international guidelines. It is followed by a collocation calibration against reference stations with analyzers to account for the impact of outside environmental factors and validate the devices’ reproducibility. Oizom has a custom-built reference station with USEPA-designated FEM reference grade analyzers. The reference station can accommodate up to 40 Oizom units simultaneously, enabling further assessment of intra-model variability using statistical measures like mean, median, and standard deviation. This ensures our device provides dependable real-time air quality data and safeguards the system’s accuracy.

ATIRA Certified Devices

Oizom devices are calibrated at our own calibration facility. The Calibration Reports are then verified by ATIRA to ensure the accuracy and reliability of the data. ATIRA (Ahmedabad Textile Industry’s Research Association) is an NABL-certified laboratory accredited under ISO/IEC 17025:2017, ensuring trusted third-party validation.

Data Logging and Connectivity:

• Modern monitors often come with features that allow for data logging and connectivity. These features can benefit long-term trend analysis, remote monitoring, and integration with other safety systems.
• Regarding data transmission, our devices exhibit remarkable flexibility, supporting a wide array of Wired and Wireless channels. They are equipped to communicate wirelessly using GSM, GPRS, 3G, 4G, WiFi, LORA, LTE, and SIGFOX technologies. For wired connectivity, they offer reliable Ethernet, Modbus, RS-485, and RS-283 options.
• The crucial data on ambient air particulates collected by our devices are efficiently transmitted to the Oizom Cloud, which can operate on either Shared or Private Infrastructure. This data is instrumental in powering diverse data solutions tailored to specific end applications.

Technology

With an IoT-based development approach, Oizom has been able to successfully unlock multiple solutions, catering to various industries. Our sensing technology works on proven working principles like NDIR, Electrochemical Analysis, Semiconductor, Optical Measurement, and Laser-Scattering. As a part of our proprietary ‘Micro Active Sampling’ (e-breathing technology), we have a smartly designed sample intake and monitoring system inside a controlled environment. This isolates the effect of the external environment on measurement to achieve 13% higher accuracy than the industry standards.
