    A lot of sensor in a decent case. All tested in laboratory and good results.

    looks good. And then in time, it turns out the rest

    Temperature readings are about 2 degrees centigrade and the humidity is 15 units lower. As for the other clues, I don't know how to trust them. Otherwise, implementation is easy and connection to the network, too. Very fast shipping and well packaged. Ultimately, unreliable device, but with too much service from Bangood.

    First of all, the rate of renewal and transmission of data is per hour. In case you set an alarm for some high price, you should be lucky to be close to exactly. The cable is too short 20cm, and there's no widget to see the values on your screen.

    After a few weeks of test operation - Measures temperature, humidity, CO2 and the pollutants formaldehyde and VOC. The former three can be easily verified - works. Only small downside - if the part is in the airflow when airing the humidity and VOC measurement goes crazy and takes high values. At least the humidity should be lower here. If the humidity in the room rises to more than 65%, a continuously increasing VOC and formaldehyde value is also indicated. I have to investigate whether this is normal, but for the price the part is serviceable. I have yet to test whether the other two sensors I ordered do the same. Otherwise, the Blitzwolf app can be set up quickly if you have not too much firewall turned on and if necessary. others should enjoy the monotonous values ;-)

    I have already bought 2. piece. Works well, with the Blitzwolf and WIFI application pairs seamlessly. The hydrocarbon caddies could be not in ppm but in um/m3 as stated by the standard. That makes it hard to count. If the device really works and measures accurately, you won't know. At night, CO2 rises, so I guess yes, with hydrocarbons, it's hard to tell there's nothing to judge or measure.
