Portable Air Quality Monitors
A portable air quality monitor may not be something you are considering buying. But you definitely should be.
Imagine going for a jog or organizing a picnic in the park. How do you immediately determine whether the air is clean and safe? This is where portable air quality monitors come into play. These useful instruments are small, portable, and provide real-time data on various pollutants, including PM2.5, PM10, CO2, NO2, and O3. They are intended for personal use, making them ideal for outdoor enthusiasts, parents, and anybody concerned about their near surroundings. Portable monitors’ value lies in their convenience and immediacy. However, it’s important to note that while they provide valuable information, their accuracy can vary and may not measure all types of pollutants.
Fixed Air Quality Monitoring Stations
On the other hand, stationary air quality monitoring stations serve as the foundation of national and regional air quality monitoring networks. These stations are carefully located in various settings, including urban centers, industrial regions, and parks, to give continuous and comprehensive data on a wide spectrum of pollutants. They’re outfitted with advanced sensors and technologies to provide accurate and dependable air quality data. This data is vital for policymakers, researchers, and public health officials to examine long-term trends, create standards, and implement steps to enhance air quality. Fixed stations provide detailed and reliable data but cannot deliver the personal, on-the-go readings that portable monitors provide.
Monitoring devices such as Oizom, at the forefront of this paradigm shift, provide comprehensive solutions that empower industries, cities, smart campuses, construction, mines, and airports to monitor, assess, and act on various parameters. The path to sustainability becomes clearer with real-time accurate data, cutting-edge technology, and a commitment to a greener future. Harness the power of data with Oizom’s air quality monitors.
Sensors Used in Air Quality Measurement Devices
Understanding the various sensors employed can provide insight into how these devices operate and what makes them tick. Let’s look at the two main types of sensors you’ll encounter: Particulate Matter (PM) and Gas sensors.
Particulate Matter (PM) Sensors
The first and most crucial consideration when choosing an air quality monitor is the types of sensors required. Almost every air quality monitor will include a PM2.5 sensor, but everything else will vary depending on the monitor. PM sensors in air quality equipment are meant to detect these invisible threats, which can harm our health. The Particulate Matter sensor module can accurately measure respirable suspended particulate matter in the ambient air. The PM sensor module design can monitor the atmospheric particulate matter concentration in real-time. The advanced support electronics of this air quality sensor make it compact and reliable. The sensor works on laser scattering technology and active sampling. These sensors can differentiate between different sizes of particles, like PM2.5 and PM10, which refers to their diameter in micrometers.
Oizom Outdoor air quality monitoring systems like Polludrone Lite, Polludrone Smart, and Polludrone Pro use this particulate matter sensor module. Therefore, the PM2.5 sensor module is used in multiple applications, such as national air quality monitoring, environmental health impact, construction monitoring, and air quality research projects.
Gas Sensors
While PM sensors monitor particulate matter, gas sensors detect numerous hazardous chemicals in the air. These gases include nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3), among others. They can originate from various sources, including automobile emissions, industrial activities, and natural events. Gas sensors operate through chemical reactions when the target gas comes into contact with a sensitive material within the sensor, changing the material’s electrical resistance. This change in resistance is measured and translated into a gas concentration level.
Gas sensors are important in the Internet of Things revolution because they enable monitoring of harmful gases such as carbon monoxide and methane. These sensors can be linked to an IoT network, providing real-time notifications when harmful levels are identified, allowing rapid action, and preventing potential accidents.
