🌡️ Advanced Temtop Generation: Accurate Recording Calibration Temperature Device Review

Useful for monitoring important air quality aspects affecting health (including Covid-19 PM2.5 criteria). Provides a real-time display of data that can be used to force home air filtration units to run at a higher fan speed when indoor pollution levels rise sharply. A great urge to open windows when outside air quality makes it worthwhile. Graphic displays: PM2.5, CO2, HCHW Would be nice: Graphic periodic displays: PM10, particulate matter (all particles/dirt), temperature, humidity

So I bought this device and I am very happy about it. I followed all the instructions and the thing just doesn't work! I calibrated it, I took it to an area where I KNOW the air is unhealthy and it showed the air to be "healthy"! Meanwhile, in my house, where the air is healthy because I use a premium air purifier, he said "unhealthy." smh! The numbers fluctuate for no reason and this device is just rubbish. I'm so sad! The battery life is not good and I really think I have a defective device…

I wanted to record more PM2.5 data than just looking at the meter every now and then. This block does not disappoint, writes to the csv log file during the day, I set it every minute. I can then draw the graphic with a spreadsheet program. Getting CO2 readings is like a bonus, I learned something about the circadian cycle that I hadn't seen in such detail before. PM10 appears to be a real measurement, unlike other units that are simply a fixed percentage higher than PM2.5 measurements. I was a…
