INKBIRDPLUS 6-in-1 Indoor Air Quality Monitor, Detects CO2, PM2.5, PM10, AQI, Temperature and Humidity with Alarm, for Rooms, Cellars, Grow Tents, Offices, etc. (PTH-9A)

Nicely work. User friendly.

why did i buy this:i do a lot of WFH and realized i get too tired and exhausted after just a hour. Dk why i bought this and found out that CO2 accumulation was way outta normal levels in my room due to poor ventilation. now i remedied the CO2 issue and also found out that my DIY air purifier works really well. normal AQI is around 70-80 normally in my region.Features and good experience with this product :built in battery lasts for a day but this device is designed to be connected to power at all times.CO2 measurement can be calibrated and is set to off by defaultbuilt like a brick which i honestly did not expectmeasurements respond pretty fast to changes which i really appreciate.has a smoke alarm kinda feature where if AQI crosses 100 it beeps.looks nice in my room.The cons and bad experience.backlight is not bright enoughexperienced a glitch where CO2 ppm was stuck at 500 had to reset the devicei wish it lasted atleast for months before chargingif there is bad ventilation temperature reading is unreliableSomething i want to say:i read a lot of reviews before buying this product and it seems like the seller is listening to feedback and fixing a lot of issues users experienced my experience till date is almost flawless except the problems mentioned above. which is also something i didnt expect. i expect this thing to last atleast 3 years or so and if it fails i will update my review as this one is not cheap at all atleast for me.overall i can confidently recommend this product if you can accept the shortcomings mentioned above

Easy to use and works as advertised.

The monitor is compact and well presentedUnfortunately it is completely inaccurate and sometimes the screen blanks out the air quality data

Pros:* Has AQI as well as CO2 monitor* All monitoring parameters are accurateCons:* AQI warning can only be turned off only till device goes off, after that it is automatically enabled again* Should have come with app and wifi support, so that historical data could have been maintained and various readings could have been tagged

On picture 3 it's mentioned air "quanlity". I think seller should correct it. As it's a scientific device, all facts should be thoroughly checked.

اعج ‏عجبني إنه يعطيني أرقام دقيقة عن نقاوة الهواء في الغرفة

I tested it by blowing some smoke, put it inside, outside... It seems to work perfectly

24 battery life makes it almost useless.

دقيق فقط في درجة الحرارة والرطوبة وللأسف باقي معلومات البيئة المحيطة غير دقيق مطلقا.

Only 24h of battery life!! Ruins the usability of it.
