The screen looks good and is not very large, although the battery does not last long and it is better to have it connected to the network always and be careful that the cable is not disconnected

La pantalla se ve bien y no es muy grande, aunque la batería no dura mucho y es mejor tenerlo conectado a la red siempre y tener cuidado de que no se desconecté el cable

I bought it on February 5,2021, and it came home to me in less than 15 days. The device is very good. I am writing this text as of April 17,2021, and it has been running 24 hours since then, that is, it has been running for 2 months. This device is actually like 4 independent devices inside its box and is a very professional device. It has the particle meter in the air that works with laser technology. It has the CO2 meter that works with infrared light technology. It has the HCHO meter that runs on electrochemical technology, and it has the TVOC meter that runs on semiconductor technology. To get the most out of your device, it is ideal to install the "TUYA" app on your mobile phone, which is available in PlayStore. And using the barcode supplied by the manufacturer, this application links your device to your home phone and WIFI. With this application, from my mobile I can know in real time the data that the device collects, even if it is out of the house, and the most interesting thing, is that it represents the graphics on the mobile hour by hour, of the data it collects from particles, CO2, HCHO and TVOC, AND SAVE THE GRAPHICS IN THE MOBILE OF MOBILE DAYS BACK. In short, a great device and has very precise measurements and very adjusted to reality, that is to say, it is very well calibrated the device. A very good purchase.

Lo compré el 5 de febrero de 2021, y me llegó a casa en menos de 15 días. El aparato es muy bueno. Estoy escribiendo este texto a 17 de abril de 2021, y está funcionando 24 horas desde entonces, es decir, que lleva funcionando 2 meses. Este dispositivo en realidad es como 4 dispositivos independientes dentro de su caja y es un dispositivo muy profesional. Tiene el medidor de partículas en el aire que funciona con tecnología láser. Tiene el medidor de CO2 que funciona con tecnología de luz infrarroja. Tiene el medidor de HCHO que funciona con tecnología electroquímica, y tiene el medidor de TVOC que funciona con tecnología de semiconductor. Para sacarle el máximo partido al dispositivo, es ideal instalar en el móvil la aplicación "TUYA" que está disponible en PlayStore. Y mediante el código de barras que suministra el fabricante, esta aplicación enlaza el dispositivo al móvil y al WIFI de tu casa. Con esta aplicación, desde mi móvil puedo saber en tiempo real los datos que recoge el dispositivo, aunque esté fuera de casa, y lo más interesante, es que te representa los gráficos en el móvil hora por hora, de los datos que va recopilando de partículas, CO2, HCHO y TVOC, Y TE GUARDA LOS GRÁFICO EN EL MÓVIL DE VARIOS DIAS ATRÁS. En definitiva, un gran dispositivo y tiene las mediciones muy precisas y muy ajustadas a la realidad, es decir, que está muy bien calibrado el dispositivo. Una compra muy buena.

I received the device in nine days after ordering. The three buttons on the base sometimes jam and don't work well. There is no key to dim or turn off the screen light. That's why the battery's running out fast. I haven't been able to run a lot of tests on the measurements. With another device to test CO2 measurement (who can measure CO2 alone) I measured it, and there was about 100 ppm difference.

Cihaz siparişten sonra dokuz günde elime ulaştı. Üsteki üç tuş bazen tutukluk yapıp iyi çalışmıyor. Ekran ışığını kısma yada kapatmayla ilgili bir tuş yok. Bu yüzden pili çabuk bitiyor. Ölçümlerle ilgili olarak çok fazla test yapamadım. CO2 ölçümünü test etmek için başka bir cihazla (sırf CO2 ölçümü yapabilen) ölçüm yaptım aralarında yaklaşık 100 ppm fark vardı.
