Main Function
Main Features
- Easy to use: connect to DC 5V, the monitor starts to work, wait for 3-10 seconds, the value is stable.
- Easy to read: Six different color prompts correspond to air quality levels. If they are all green, they are very healthy.
- Accuracy: The sensor uses the principle of laser light scattering. That is to say, the laser light is scattered on the suspended particles in the air, and the scattered light is collected at a certain angle at the same time, and the curve of the scattered light intensity changing with time is obtained. Furthermore, the microprocessor uses an algorithm based on Mie (MIE) theory to obtain the equivalent particle size of the particles and the number of particles with different particle sizes per unit volume.
- AQI: Meets EPA 454/B-18-007 standards
Air Quality Monitor
PM1.0, PM2.5, PM10, AQI, temperature and humidity, suspended particulate matter measurement of different diameters.
This air quality monitor indoor can be switched between Celsius and Fahrenheit, data color is changeable, and visual alerts.
This air quality tester has a translucent design for more accurate detection and better heat dissipation.
Notes
The monitor does not have a built-in battery. If mobile use is required, a mobile power supply can be used to provide DC 5V to the monitor.

this item works great for such a low price. I us it in my office and factory. I wish it had a data connection.

(Update #2). I got the new meter and it is not much better, I took photos driving around different places and it's still pretty much 0. Sure, it works if you get it near smoke but I've yet to have the outside air get past 1 at anytime. What's up Domino's(Update#1); I exchanged it for another, raised stars from 1 to 4, it too reads all zeros in my house but if I take it outside this one goes up a little. Maybe I just have really clean air around here (Woodland, Wa) , I'm running 2 Winix 5500-2, a Honeywell and on other off brand air purifiers. Still more testing to come when I get on the road. I will update review again. I heard good things about this but my first one didn't function.(Original Monitor ) Previous review; $45 Thermometer, no way my air is that clean. At first the reading went higher and higher, then come down lower and lower until NOTHING! I've been trying different power supplies, the first 2 were apple brand so I don't think it's the power. I also tried waiting 30 min and power on again but it doesn't work

At first this unit performed as expected. It was easy to set-up, easy to read and seemed accurate.Yesterday it suddenly began indicating a reading of 3,569ppm for air quality, which would basically mean I was choking on toxic air. Except I wasn't. So I did a power-off cycle and it came back reading 0ppm. Blowing smoke at it does not change the reading. Another power-off cycle does not restore the AQI monitor.I know of no way to reset or recalibrate the AQI sensor, so that means that the unit is non-functional for me.

This is way beyond my expectations. With this price, this product provides a colored back-lit LED screen, with temperature, humidity, and all kinds of PM numbers and particle counts!! The only downside I can think of is no battery. You have to use your own power bank to make it portable. But I guess asking the seller to provide a rechargeable battery at this price is no different from robbery...

Very nice little toy to measure your indoor air quality. I have nothing to compare with, but the numbers look pretty accurate to me.

Unit displayed low numbers in the 4 to 1 range for PM2.5 so I immediately knew something was off...Let the unit 'settle' for about 10 minutes...then particulate readings were 0...also noticed the fan stopped working and smelled burned.I immediately ordered another unit and started the return process on this one...will update review when I receive new unit. As other reviewers have also had bad luck, these seem fragile. We'll see, but off to a not so good start!

I bought one of these based on a YouTube video because it looked pretty accurate and offered a lot for the price. However after receiving two units I can safely say the accuracy of these is definitely hit or miss. Unfortunately the two I received were wildly inaccurate and couldn't even agree with each other. With no way to calibrate them they are useless to me and are being returned. For about $20 more I found another brand that offered better out of the box accuracy, and wifi connectivity allowing the use of an app to track data trends, calibrate all of the sensors, and receive alerts if you'd like. I think with some tweaks this unit could be very good, but in its present state I can't recommend it.

It reads particle count and it does it well. The exterior readings align with my weather forecast and I see near immediate changes when I start generating dust. I think it does use an averaging function over time. I have seen a few odd spikes, but otherwise I have come to trust its accuracy.That's it. It's very small very easy to plug and go. I put magnets on the back to attach to my breaker panel in my shop.This does not try to be very complicated, so find other products at a higher price point if you want customization, bluetooth or data recording.

I have a professional quality AQ monitor and this one compares very well in terms of the accuracy of the PM2.5 reading. The response time is good. Very cool to see the number of particles in each size range.With no internal battery, moving the unit from room-to-room is not convenient. The open framework case, while cool to look at, means you need to blow the dust off regularly.

Air quality ratings in my area spiked yesterday but unit continues to display zero particulate. I dripped a pinch of baby powder near the unit but the '0' readings don't change. This may be a 1-off bad unit so I'll re-order and update review later.

The features (pm 1.0, 2.5 and 10) for the price is great. I like the minimalist design. And the screen is very bright and readable. I' ld love to be able to change the screen layout to show what I care about bigger and the other stuff smaller (or not at all), but the default design works at least.For the first couple days, it worked exactly as expected. But since, the monitor will have spells where the PPM readouts are all zero. Now, I am not a slob, and I have fresh (cheap) filters in my air intakes, but my house is not a semi-conductor clean room! My guess is that the detectors are not very robust or sample too little air to be always accurate at the lowest concentrations.Normally is does seem to work, although the ppm numbers are normally all single digits (under 10). I wish it had the option for battery operation. The short micro-usb cord makes for limited placement options. And speaking of micro-usb, there definitely needs to be some supports for that one area. Minimalist is fine. But the port is soldered onto the board with absolutely no external support. The slightest tension or accidental tweaking seems likely to rip the whole port right off the PCB!But all in all, so far so good. I will update down the road if the durability isn't there.
