I ordered this one since it reads out in tenths. I just need that extra resolution for my satisfaction.  :lol: These will be great for monitoring humidity in garage, basement etc.

GRLevel X Software / Grlevel3 auto atart up and publishing
« Last post by dasman on Today at 02:04:32 PM »
I am looking for help getting my Grlevel3 to auto start, zoom, and start publishing after my computer reboots. I reboot my computer daily at 3am. With VWS as my weatherstation software, i need to reboot to avoid the inconsistent software crashes. I have downloaded Autoit, Startwatch, and autohotkey. Honestly these programs are beyond my technical abilites(almost none). So im looking for someone to set it up for me. I am willing to make a "donation" to that person for their help. Is there anyone that can set it up for me?

I ran across this cheap indoor sensor that i just had to order, it is spec out as an sht31 sensor. The sensor being used is the sht 3x on the picture but says .5 +/- temp and 2% humidity. It would make a nice cheap unit to use for testing purposes. Here is the link https://www.amazon.com/gp/product/B01HDW58GS/ref=od_aui_detailpages00?ie=UTF8&psc=1

If it's the same as our 31's nice little unit. Easy to read.

Weather Display, for example, has a tweak that says IF the humidity is 95% or greater, display as 100%



Cumulus has a similar but it's 98% I didn't have SHT31 that would make 98% until this new one and yes I have 98% = 100% on Cumulus for website. I can watch actual humidity on my Envoy8x display or console.


For anyone wondering about using double filters I started and don't see noticeable response time differences, accuracy was unchanged comparing with another sht31 side by side so recommend on new sensors to double up filter on new units. I just washed old and installed with the new. This at least doubles the filtration I'm thinking.

Measures indoor temperature and humidity from -4 to 158F (-20 to 70C) and 1-99% RH

Professional accuracy: +/- 0.5F, +/- 2% RH with manual calibration option

It's due here Tuesday and i will find out keep in mind the sensor determines the accuracy and it is  an sht sensor so i got my fingers crossed.

Well, it *IS* pretty, but is it truly accurate? AcuRite does not have a stellar reputation for accuracy...in spite of its name.

I have read this discussion and yet still am wondering what the technology is that the high priced, more-likely-to-read-100%, type of sensors use?  I assume we're talking RM Young, Vaisala, Campbell Scientific and perhaps a few others. 

Is it an entirely different technology?  do they actually measure dew point (doubt it from looking at most of the sensors on-line) and then do a conversion?


It's the same technology just different manufacturing process with tighter tolerances. Of course the tighter the manufacturing tolerance the higher the manufacturing cost but you will get a better spec'ed sensor and better performance above 90%. Apples to apples, the SHT31 chip itself runs about $5. My Vaisala Humicap chip runs $80. SHT31 spec is 2%, Vaisala Humicap is 1%. An engineer once told me that once you get down around 2% spec, it costs a lot more to shave off another 0.5% in manufacturing.
