PurpleAir PA-II Indoor Laser Particle Detector

The PurpleAir PA-II is a smart home device. The device can be viewed through the PurpleAir web site map or connected through an IFTTT channel. This makes it easy to integrate the PA-II data with other smart home platforms. The device will also send you alerts and a detailed report every day. It’s a great addition to your home automation system. You’ll be happy you have it in your home, and you can use it as a tool to monitor the air quality in your home.

Air quality monitors

PurpleAir PA-II is an indoor air quality monitor with dual-laser particle detectors that detect the presence of PM2.5, PM10, and PM1 particulates. PM2.5 particles include tobacco smoke, soot, pollen, and mold. The smaller of these particles may be easily inhaled or pass through the bloodstream. The larger, PM1 particles can cause health problems if inhaled in sufficient quantities.

This monitor uses two identical laser particle counters to detect airborne particulate matter. This allows it to measure PM2.5, PM10, and PM1.0 in real time. The count data from each device is then converted to mass concentrations. The monitor also measures temperature and relative humidity. Despite its numerous benefits, the PurpleAir PA-I is not perfect. You should know what you’re paying for before you invest in one.

In addition to its ability to detect smoke inside a home, the PurpleAir PA-II has other useful features. It provides continuous measurements of indoor and outdoor air pollution. The data it provides can even be used to drive smart air cleaners and health devices. In addition to measuring air quality, it can also monitor the quantity and types of smoke in your home. When used properly, the PurpleAir PA-II is a great choice for monitoring air pollution inside your home.

Purchasing a quality air quality monitor for your home can protect your family from health risks. These devices detect multiple pollutants in the air and will alert you if the levels become dangerous. This information can help you make better decisions about protecting your family and moving away from high-pollution areas. There are also different models available, ranging from DIY units to more expensive devices that need professional installation. Consider your budget and the type of pollutants in your area when buying a quality monitor for your home.

Laser particle detectors

The performance of PurpleAir PA i indoor laser particle detectors is limited. The sensor only detects particles 0.5 mm in diameter and above. It can also detect particles 2.5 mm and larger, but at this size, it is impossible to determine their number. Because the sensor is sensitive to humidity and dust, it is unlikely to be effective for use in humid environments. Instead, it relies on algorithms to derive its particle count.

The PA i Indoor Laser Particle Detector is designed for industrial and commercial applications. It has redundant laser particle detectors to measure particulate matter, including smoke. It is also user-friendly. However, the PA i does not come with a smart phone app, which many consumers have come to expect with smart home products. Although it does come with a website, it’s a bit limited in its features.

The data collected by PurpleAir can be grouped into different categories. The EPA uses the air quality index to translate its measurements into levels of concern to humans. Therefore, PurpleAir data is more informative than the raw monitor values. The data are reported in the form of a chart. EPA recommends using a reference monitor with air quality index (AQI), which provides much more useful information than a simple reading. PM10 is the most problematic because it can enter the bloodstream.


If you’re looking for an air quality monitor that’s both user-friendly and affordable, look no further than the PurpleAir PA-II indoor air quality monitor. While not smartphone-compatible, the PA-II offers a wealth of data on indoor air quality. It can also be integrated directly into a smart home. This allows it to drive air cleaners and other health devices that improve indoor air quality.

The PurpleAir PA-II indoor apps let you check the air quality in your home. The app also displays the U.S. Air Quality Index, which is a color-coded scale from 0 to 500. It also allows you to monitor the ozone and dust levels in your home. The app also provides a map that shows you the location of every sensor. With this data, you can choose whether to use the app to monitor indoor air quality.

The PurpleAir PA-II is a portable air purifier that can be mounted on a wall or ceiling. It has a single screw that fastens it to the wall or ceiling. It comes with a weatherproof cover that protects the laser particle detectors. However, this cover has a hole in it for air flow. The PurpleAir PA-II is powered by a small plug-in power supply, which can be located near an outdoor 120 VAC outlet. In order to install it, you need to cut a hole in the exterior wall where you can route the wire.

The PurpleAir PA-I Indoor cost varies depending on its features. It measures fine particulate matter (PM2.5), temperature, humidity, and pressure. It is compatible with most types of indoor air quality monitoring systems. PurpleAir’s TES-5322A monitor can measure PM2.5 and volatile organic compounds, as well as humidity, temperature, and pressure. It can also detect specific toxic chemicals such as lead, mold, or dioxin. It is also compatible with most other kinds of monitors.

The price of the PurpleAir is relatively inexpensive compared to many other air quality monitors. Unlike traditional instruments, it can be easily used in areas with poor air quality. In fact, the Lawrence Berkeley National Laboratory used a PurpleAir sensor during a wildfire to test the accuracy of air quality monitoring. The results of the study showed that low-cost sensors had strong correlations with regulations grade instruments when changes in air quality occurred.


The PurpleAir PA-I is an air quality monitor that monitors PM2.5 and ozone levels. It has two particulate matter sensors and is able to measure these measurements with high resolution. Unlike traditional air quality monitors, it can provide spatial and temporal resolution. This allows it to detect small changes in air quality and identify potential problems before they become major problems. This is a particularly important feature for people who are concerned about their children’s health and safety.

The sensors used in the PurpleAir have spatially variable sensor correction factors, and the measurements can be linearly correlated with the AQS. This means that the PurpleAir PA-I sensor has a good correlation with the AQS. It has a high R2 and slope, which ranged from 0.73 to 0.85 for indoor air quality. The slope and R2 values were lower than the data obtained by Bi et al.

Comparison with other monitors

In a Comparison with other monitors, the LG 24GM77 shows the highest brightness uniformity and a lower response time than its competitors. The display also has a good contrast ratio, with a 3000:1 static contrast ratio and a full HD resolution. The maximum deviation was 11% in the top right quadrant, and less than one percent elsewhere. The contour map below shows how the brightness distribution differs by percentage from the brightest point, with darker greys indicating greater deviations.
