Hubitat with Homemade Temperature, Humidity, Pressure and Light sensor

It look normal. Your log show other cluster as well like the light sensor. Based on my experience, light sensor fluctuate a bit.

Fyi, If you use filter value of 1, you basically disable filtering.

Did anyone get the illuminance to output lux ?

Mine still shows

Mike's driver shows Lux correctly

You can scale the Illuminance value using @iharyadi’s driver. I use a scaling value of 2.8 which basically outputs values from about 0 to 10000.

Correct ?

ogiewon · August 1, 2019, 11:07pm

Yes, that’s what i use. It’s definitely not a truly calibrated absolute Lux value, but it at least provides a nice working range to use in automations.

Thanks !

@iharyadi I'm thinking of putting one out on my patio. Do you have locations on the board that should not be sprayed with waterproof electronic sealant ?

iharyadi · August 2, 2019, 2:07am

There is a square silver looking sensor that has very small hole. That is the temperature sensor. Please do not coat that sensor.

Which sealant are you using?

anon61068208 · August 2, 2019, 2:21am

This one ?

iharyadi · August 2, 2019, 2:22am

I use nail polish. It is probably not good for long term. I have not tried a proper sealant. I suppose they will work much better.

anon61068208 · August 2, 2019, 2:27am

I used this on my patio TV 3 years ago. Not 1 problem.

anon61068208 · August 2, 2019, 2:33am

I also bought this one but haven't used it yet.

And if you want to use a brush instead of sprays use this instead.

anon61068208 · August 2, 2019, 2:36am

@iharyadi where is the light sensor located ? I don't want to cover that either.

iharyadi · August 2, 2019, 2:39am

There is a glass like sensor next to the zigbee radio opposite to the temperature sensor.

I am thinking about getting the permatex. If it work well, let me know. I rather worried about using the spray.

anon61068208 · August 2, 2019, 2:43am

Is that the one with the 2 copper strips ?

The permatex is the one I would use.

In the picture you posted, it is the sensor at the bottom of the picture, with the U3 or V3 label next to it.

I have had one on my screened in porch for over a year with no special protection measures. It looks like new. No sign of any corrosion whatsoever.

iharyadi · August 2, 2019, 2:48am

Yes u3. If the coat is clear, i would actually coat this sensor. There is no restrictions on this one as long as the coat is not colored.

anon61068208 · August 2, 2019, 2:56am

Neither sprays are clear. The first spray dries red. The other I think is yellowish.

Quick question, without reading the 539 posts here, is there a parts list for building this available?

Thanks Again
