S_RADIOACTIVITY #567

Open henrikekblad opened 8 years ago

henrikekblad commented 8 years ago

New device type for geiger counters. Is S_GEIGER_COUNTER better?

The device sends in radiation level (uSv/hr) as V_LEVEL

usv = cpm * x;

x = tube constant

Is it still useful to send cmp value to the controller?

The clicks measured is, what the tube has registered. And this is what you hear. 😄 I really like to see this value too.

The usv number form above is quite small when measuring every minute. If I understand you right, you would multiply it by 60 to have a relative value per hour. Am I correct? For a UI I think this is the value you want to see. The question is, isn't this better done in the controller?

With V_LEVEL, you would average all of them them and multiply by 365 * 24 to get the total radiotion.

With the cpm, I can just sum them up in the time and multiply with the factor of the tube.

I vote for V_LEVEL in uSv/h because that depends on the tube constant. And I also vote for V_PULSECOUNT for cpm so that other calculations can be made.

Another vote for both values - uSv/h to display and cpm as extra info

Hej,

what's the status here? I'd like to add a Geiger Counter to my Domoticz installation and using S_DUST and V_LEVEL seems silly …

I second the vote for cpm and uSv/h …
