I am working with some sensors and sending data to a public web server via http, I was thinking this server can be possibly used by more people to send their data and server displays a chart.

I was wondering if there is a IOT industry standard when sending certain type of data, so that in future I don't need to rename this or change documentation to be more compatible or more intuitive.

For example when sending a "motion detected" ping, do I go with `pir=true`, `pir=1`, `motion_detect=true` ?

Then for example when sending temperature, it would be much better `temp_celsius=30` then just `temp=30`.

It should also make developers job much easier if there is a certain standard. Is there one ?
