All the sensors! - Which device?
#4
Hey,


Quote:In case of SM-G900T (Galaxy S5) there is a sample size of 2

- does it mean 2 people have submitted their information about their Galaxy S5s?

Yes thats right! Here is some more Information you can find on the database webpage:


Quote:This is the number of devices that contributed to this entry in our database. Note that while each user can submit their data multiple times, we only take into account the submission with the lowest standard deviation. Hence, the sample size corresponds to the actual number of physical devices that have been tested for this entry.

But keep in mind we dont know how accturate our users follow the test-conditions. Maybe someone discovered the database experiment on a train journey and submits significant worse data due to vibrations.


Quote:E.g. Samsung Galaxy S5 has a humidity sensor on that website.
SM-G900T (one version of Samsung Galaxy S5) in phyphox database has no humidity sensor available.

I think you will not be able to use the temperature/humidity sensor with phyphox. If I unterstood Sebastian (Staacks) right phyphox is scanning for a sensor which is named "temperature" (or something like "temp" is in the sensors name). Unfortunately some sensors are just named by there manufactures name. For example if there is a BME280 sensor (temperature, humidity, pressure) and it is named like "BME280" or "Bosch BME280" phyphox will not recognize the temperature sensor. This naming problem is a consequence of the fact that these temperature sensors are not designed to measure the enviroment temperaure but the device temperature as a hardware safety feature (prevent overheating).
I also fully agree with Sebastian (SJS) that a internal temperature/humidity sensor is not that useful (except you are interested in the smartphones temperature while charging or different power modes in general). A bluetooth low energy sensor as the sensortag or a diy arduino project will suit much better.


Best wishes
