Temtop Air Quality Monitor PM2.5 Bluetooth Thermo-Hygrometer Digital Hygrometer Indoor Humidity Gauge for Home Office Humidity monitor for Bedroom, Livingroom S1+

I found this a little tricky to keep the connection ... especially after re-naming the device, but its working well with the default name.

My son has quite bad asthma and this helps me keep control over the air quality in his room at night.

Does exactly what I wanted. Fab instruction, clear uncluttered display and very sensitive.

I use this air quality monitor daily in my bedroom to check for the quality of air. I bought a pair of these devices, a slightly different one, and I like them. The engineering is good, they are robust and they're very easy to charge up as usb-c devices. In this area there are a lot of expensive devices with questionable capacities that these are good and as far as I can tell accurate

Once re-calibrated, works well. Phone app is quite good. Reccomended.

Temperature display was out by 4-5 degrees centigrade. I had a feeling it wasn’t accurate so I tested it against two normal room thermometers to confirm. That undermined my confidence in the accuracy of the pm2.5 readings which is why I bought it so I’m sending it back

Ich hatte vorher zur Kontrolle der Feinstaubwerte meines Holzofens (Raumluft Wohnzimmer) zwei andere Modelle im Einsatz die eher zufällig gewürfelte Werte angezeigt haben (auch bei erkennbarem intensiven Rauchgeruch noch AQI im grünen Bereich) . Dieses Gerät hier hat mich positiv überrascht, der PM2.5-Wert wird schnell und glaughaft präzise ermittelt. Jedes Öffnen der Ofentüre wird erkannt und als Auschlag angezeigt. Im Abgangsluftstrom meines ebenfalls gekauften HEPA-Raumluftfilters werden Werte von 8 - 10 mikro Gramm/m3 angezeigt. Das bestätigt die Filterwiksamkeit mit dem von der WHO empfohlenen Grenzwert von 10. Der Akku hält mehrere Wochen ohne Nachladen, toll. Auswertungen über die App funktionieren auch. Von mir volle Kaufempfehlung!

I have congestive heart failure - I've lived with it for years but last summer's fires from out west and Canada, coupled with a supreme heat season took me out for the whole summer. Even inside I had problems breathing. I wanted something fairly inexpensive to just help me identify higher risk days, confirm what the air quality inside our house was, and also show humidity (because I can't breathe when its humid, either). It was a weird mixture re: air quality and humidity but this works GREAT. Its USB charged but honestly I think I've only charged it twice in a month and that was me being proactive, not it showing low battery. It is not backlit. I don't care but FYI if that is a big deal for you.

Great choice good value for money and accurate data

Muy buen producto
