Air Quality Sensor – What You Need to Know
**What is an Air Quality Sensor?**
An air quality sensor measures different pollutants in the air. These sensors can track factors like temperature and humidity. They measure gases such as carbon dioxide, carbon monoxide, and ozone.
They also measure formaldehyde, benzene, PM2.5, PM10, and more. These sensors are important for air purifiers and ventilation systems.
**What Do Air Quality Sensors Measure?**
Air quality sensors can find tiny particles like PM1, PM2.5, and PM10. They can also detect harmful gases. These gases include ozone, carbon monoxide, carbon dioxide, methane, formaldehyde, and TVOCs.
These sensors also measure environmental factors. They track temperature, humidity, UV exposure, and light levels.
**Functionality of an Air Quality Sensor**
Air quality sensors work in different ways to measure gases and tiny particles. For example:
The **laser scattering principle** is used to measure the amount of tiny particles, like PM2.5 and PM10.
The **non-dispersive infrared (NDIR)** technique is used to detect carbon dioxide levels.
The **electrochemical principle** helps us measure the amounts of gases like ozone.
The sensor gathers pollution data from the environment. It sends this data to a processor for analysis. The processed information is shown as charts or numbers. This helps users understand the air quality clearly.
**Indoor Air Quality Sensor Options**
1. **Compact Air Quality Sensors for Home Use**
Small air quality sensors are popular for indoor use. They can measure PM2.5, VOCs, and formaldehyde (HCHO). They also calculate the Air Quality Index (AQI). These sensors are small and easy to use.
They can sit on tables or nightstands. Users can easily switch between readings by pressing a button. The displays are clear and easy to read. Their low cost and usefulness make them easy to find on sites like Amazon.
**Temptop M10**: This model is good for home use. However, it does not have advanced features like Wi-Fi or a mobile app. Because of this, it cannot track data over time or show outdoor air quality from nearby stations..
It also does not give tips for better air quality. You cannot access data through smartphones. However, its simple design may attract people who want an easy monitoring tool without extra features.
2. **PM Air Quality Sensors for Workshops**
PM air quality sensors are made for industrial settings. They measure particulate matter such as PM1.0, PM2.5, and PM10.
These devices are often placed on walls. They have cases that are waterproof and dustproof for tough conditions. This includes being around water vapor or smoke in factories. An outside filter allows particles to pass through but keeps out moisture and dust.
Unlike simpler models, these industrial sensors do not have screens for real-time data. Instead, users must log into software to see the results.
**PM Sensor Example: RS-PM-*-2**
This industrial particle sensor uses laser scattering technology. It also collects data at two frequencies. This helps measure particle sizes in a specific volume.
The ModBus-RTU protocol sends results and is more resistant to interference than wireless options like Wi-Fi. This makes it a good choice for tough environments.
3.**Multifunctional Air Quality Sensor**
The air quality sensor is a small round device that measures 168mm wide. Its design lets you easily snap it to a base. This makes it simple to install on walls or ceilings.
Made from strong ABS material, the sensor is durable. It also has a sleek look that fits well in different spaces.
This sensor has many functions. It measures different environmental factors. These include CO2, temperature, humidity, and PM2.5. It also measures PM10, atmospheric pressure, and light levels. The sensor can detect TVOC with a special probe.
It measures formaldehyde, ozone (O3), and carbon monoxide (CO). It also detects methane (CH4) and oxygen (O2). Additionally, it measures sulfur dioxide (SO2) and nitrogen dioxide (NO2). It can also detect hydrogen (H2), hydrogen sulfide (H2S), and ammonia (NH3), among others.
Its strong monitoring features meet the needs of public spaces and more. A main limitation is that there is no built-in display. This means you cannot read data directly from the device.
The sensor uses high-quality parts for better clarity and stability. It can support RS485 output or Wi-Fi wireless transmission, based on how it is used.
The RS485 connection lets you send data up to 2000 meters. You can access it through a monitoring platform. In contrast, Wi-Fi needs a local network to connect.
Setting up device parameters is easy. You do not need a USB driver. Just use a USB data cable to set it up.
4.**Composite Air Quality Sensor**
This new version of the air quality sensor has important upgrades. It can still measure temperature, humidity, PM2.5, PM10, and atmospheric pressure. Also tracks light, TVOC, CO2, formaldehyde, and ozone (O3).
It also measures carbon monoxide (CO), methane (CH4), oxygen (O2), and sulfur dioxide (SO2). Can also detect nitrogen dioxide (NO2), hydrogen (H2), hydrogen sulfide (H2S), ammonia (NH3), and other gases.
The has a 4.3-inch LCD screen with touchscreen features. This lets users see measured values and change device settings easily. This makes it great for places like offices, schools, supermarkets, and other indoor areas.
This sensor alerts you when gas levels are too high. The screen turns red to show there is a problem.
It sends notifications by email, text, and calls for quick action. With 24/7 online monitoring, it helps improve indoor air. This also makes the air in cities better.
Outdoor Air Quality Sensor
Multi-Gas Solar Radiation Shield
The multi-gas solar radiation shield has many sensors inside a strong case. This case is built for long-term outdoor use. It can detect several gases, such as TVOC, formaldehyde, ozone, oxygen, hydrogen sulfide, methane, carbon monoxide, nitrogen dioxide, sulfur dioxide, hydrogen, and ammonia.
The system has a microprocessor that handles data. It sends RS485 signals for monitoring in real-time.
The solar radiation shield has strong anti-UV materials. These materials help with waterproofing and dustproofing. They stop heat from affecting performance. This ensures steady performance even in sunlight.
This device is made for industrial use. It can be set up at places with high pollution, like sewage outlets. It helps monitor emission levels and reduce environmental impact.
Dust Monitoring Equipment
The dust monitoring system is more than just regular sensors. It offers a full monitoring solution. This system has several parts.
– It includes a monitoring unit.
– There is a data processing unit.
– It has a data transmission unit.
– There is also a display unit.
– Finally, it includes a video character overlay unit.
The system uses hardware and software to collect environmental data. It has many sensors that gather this data. The information is sent to a visualization platform. This platform allows for real-time analysis at all hours.
This system is mainly used in construction areas or industrial buildings. It monitors PM2.5, PM10, and total suspended particles (TSP). It also tracks noise levels, wind speed, direction, and force. Additionally, it measures atmospheric pressure, temperature, and humidity.
Data can be shown on LED screens or accessed from a PC or mobile device. Installation can be more complex than for standalone air quality sensors. It lasts longer and can check more conditions. This makes it very dependable in tough situations.
