RE: Humidity

I though I had that as part of the temperature one, but maybe that part was never published

Thanks but my interest was on humidity.

If anyone cares I made a simple wrapper using htu21d:

Hi there,

I have some of my old repos here:

Hi Anssi,

Thanks for feedback,
I also assumed this API was out of scope.
I just wanted to share some experimentations.

About aligning API, I just pinged Kenneth on this ticket:

https://github.com/rzr/generic-sensors-lite/issues/14


Track this ticket if any interests,
or find me at FOSDEM this weekend.

Regards

Hi Philippe,


Kenneth drafted a Hygrometer API back in 2016, see:
https://github.com/intel/zephyr.js/issues/96


The spec repo is no longer online. Kenneth may still have a local copy he can push somewhere if there's interest. Currently, this API is out of scope for this Working Group.

Thanks,

-Anssi

Hi,

Recently I got a request from community to implement a humidity sensor
in generic-sensor-lite module:

https://github.com/rzr/generic-sensors-lite/issues/13


I made it simple with just a "level" property [0-100] that would indicate a percentage of humidity.

I was wondering if any specification has been already proposed,
I've seen a couple of w3c work with ambienthumidity and relative humidity ...

Now about use cases, well to start with one let's imagine that a mobile device which is in a too humid place it should raise an alert to use to avoid rust or damage.

My 2cents
