37 ° - Chinese bracelet that measures pressure (Actually, no): post-caution

Good day!

Due to the fact that adding the ability to measure pressure to the tracker is something like a search for the Grail for companies, some are beginning to speculate openly on this. This was a 37 ° bracelet. We will briefly tell about it.



The gadget has not yet gained widespread popularity, it has already been imported into Russia and is noticeable to some. For example, our friends from Lifehacker are interested in them , and, given the number of their readers, many may hurry to get a “great Chinese medgadzhet” before the review.

The bracelet is issued on Aliexpress and on JD at the request of “blood pressure”, and comes to us under the name 37 °. Landing, on which he meets, very “gracefully” bypass in the artificial feedback of the happy owners the topic of “pressure”: something like, how great it is to be able to measure pressure, or, so many functions, everything in Russian, but also the possibility pressure measurement is not at all ...

In general, to be honest, it is not here either. But it is worth noting that everything is true in Russian. From the moment when wristwatch was written about w3bsit3-dns.com in 2015, something has changed: the software has somehow been transferred.



The rest is all the same green flashlight, which makes the measurements with about the same accuracy as the 1S from Xiaomi . That is, in any way. For example, compare three measurements: pulse on the mi Band with a difference of a minute and pressure of 37 =)



The combination of random numbers is shown without any dependence on where you measure, though, excuse me, apply it to your head: here is the pressure from the foot.



Of course, there is nothing in common with digital or analog tonometer, however, to understand that the device does not measure anything, it is enough to take several measurements in a row: the optical sensor cannot diverge in equal conditions by such a number of units.

Actually, after the pressure, immediately checked the pulse for Lifetrak and Microsoft Band - also nothing like that. So all other metrics that were potentially of no interest and did not bribe users, we did not analyze. Be careful, the device is sold under different names, but it always looks like this:



Take care of yourself!
