A part of the review has been auto-translated.
it seems to be a good quality, the screen seems decent, but the plastics does not feels premium, but feels thick, so at least it feels solid, the readings also looks accurate, and easily readable, we'll see how it lasts. the delivery Took 11 days, from the bought, to be at my office, and the package was Ok. good service from Banggood.
Arrived in 2 weeks... Excellent screen visibility, different values detected (compared with other devices proves accurate). Recommended... The value for money I always great, and difficult to match from other products on sale here...
prodotto di buona qualitá, ho testato i sensori ed effettivamente si aggiorna in tempo reale, consigliato
Compared it to values from BME280 and CJMCU-30: CO2 good, temperature 1degC off, humidity 11% off, TVOC: have no formula to convert mg/m3 to ppb. Overall good value for price.
NO COMPROMISE, SUPER....
Goods received, service is fast and functional
The main CO2 measurement is responding not only to CO2. I've opened a canned fish on the same table with the detector and, in a short time, the CO2 indicator jumped from 700 to 2300. The HCHO and TVOC numbers seem to be derived directly from the CO2 readings only. I think it is using one single general air quality detection device, which is sensitive to everything. At least when you move the detector from inside to outside, it indicates a lower CO2, HCHO and TVOC concentration. The bar-style display at the bottom is a good general indicator of air quality. For the low price, it's still useful and worth having. Easy to read display.
No
Good little module and quick to view the data
I think its working well.....thangs!!!!
