Temtop M10i WLAN-Luftqualitätsmessgerät für PM2,5 TVOC AQI HCHO Formaldehyd-Detektor, Echtzeit-Datenaufzeichnung

I purchased this air pollution sensor with Wi-Fi connectivity to facilitate a study on indoor air quality, aiming to monitor an enclosed environment continuously for 24 hours. Initially, the device connected seamlessly; however, I encountered intermittent disconnections—approximately two to three times daily—necessitating manual reconnection through the accompanying application. This issue has persisted for approximately two weeks, resulting in significant data loss and rendering the sensor ineffective for the purposes of my research. Additionally, when used alongside the Temtop LKC-1000S+ 2nd, I observed substantial discrepancies in the readings of formaldehyde (HCHO) and volatile organic compounds (HVOC), with the M10i sensor reporting values approximately 50% higher. Overall, the experience has been rather disappointing.

It second already unit purchased, first operate for about 2+ years, as we know sensors have line span, in general reading was ok, but some strange noise, so decided to buy replacement, new arrived and work well, only negative side, the front glass has some defects, not visible a lot but still, however decided to leave it as it is, but normally better quality was expected. otherwise, a good product which work as intended.

I am loving loving this product. Ive recently made a feature brick wall in my home and was concerned over the dust particles it would cause. The sensors are quite sensitive and are quick to pick up any changes. I am not the most technically minded so just being able to press a button and have the information displayed is also a bonus. It has made me more aware about having more ventilation in my home and be more select with air fresheners, etc. I haven`t hooked it up to my phone yet but I think I will be even more conscious about the air quality. Its also brilliant for helping you to stop smoking!! Well worth the money.
