El dispositivo en sĂ es poco preciso en cuanto a las medidas que realiza del aire que resultan poco creĂbles. Da la sensaciĂłn de que es extremadamente sensible y ademĂĄs tiene cierto retraso en las mediciones. Si por ejemplo pulverizas en el ambiente un poco de ambientador en aerosol en la estancia en la que se encuentra el sensor en seguida el indicador de CO2 alcanzar las 5.000 ppm (el tope que es capaz de detectar) y se mantiene sin variaciĂłn en ese registro durante varios minutos. Aunque se abra la ventana para renovar el aire de la estancia mantiene ese valor en el display mucho tiempo para despuĂŠs empezar a descender rĂĄpidamente. Es como si fuera con retraso. Las variaciones en las medidas tiene una mucha oscilaciĂłn y sin explicaciĂłn alguna.
La duraciĂłn de la baterĂa es inusualmente baja, ya que no llega ni a un sĂłlo dĂa, unas pocas horas mĂĄs bien, asĂ que habrĂa que estar cargĂĄndolo cada 3 Ăł 4 horas para tenerlo siempre operativo, algo muy poco prĂĄctico, imposible de mantener a largo plazo. Eso prĂĄcticamente descarta el uso estĂĄtico de este dispositivo para convertirse mĂĄs bien en un sensor "bolsillo". HabrĂa que llevarlo al lugar en el que se quiere realizar la mediciĂłn, lo enciendes 5 minutos , tomas nota de los valores y lo vuelves a guardar.
Por el precio que tiene me imaginaba que no era un aparato de precisiĂłn, pero sĂ que me esperaba algo un poco mĂĄs fiable. No lo volverĂa a comprar ni aunque lo vendieran a 1âŹ.
Attention Potential Buyers,
I purchased a CO2 sensor from Amazon, expecting a reliable product. However, what I got was a complete sham. This device, advertised to measure carbon dioxide, is actually detecting ethanol (C2H6O2)! It's a total misrepresentation and could lead to serious safety issues if you're counting on it for accurate CO2 readings.
Don't be fooled by the product description. This sensor is not what it claims to be, and buying it would be a waste of your money and potentially dangerous if you need accurate CO2 measurements. I strongly advise against purchasing this product. Amazon needs to step up and remove this fraudulent item from their listings immediately.
Spread the word and save others from this scam.
The device reads out and displays the wanted values. However the battery is total cr*p. It only last 2 hours with a full charge. Not worth the money.
Bij uitpakken ontbreekt een usb-c oplaadkabel en de verpakking was niet dicht. Vermoedelijk een retourzending geweest.
