RE: Comparative shelter for probe t° - tobyportugal - 05-03-2022

Hello,

Reference point my Barani + SHT35 in Portugal at home.
You can see the different behaviours of the shelters and sensors, especially the behaviour at the beginning of the heating.
A 4-probe Comet will soon be started up. Same shelter, same location but different probes (SHT35-SHT75-SHT31).
I still have to find a PT100 solution.

Have a nice weekend everyone.

Hello,

For those interested, various situations with different drifts depending on the situation.
Barani + SHT35 (reference point)
Comet + SHT35
Comet + SHT31-LSS (Davis VP2)
Barani (prototype) + SHT45 without filter.



If we take the SHT45 without filter as a reference point we can see the reality of the response time.
Well explained: https://www.baranidesign.com/faq-articles/2022/7/25/how-to-test-an-air-temperature-sensor-response-time
Ref SHT35 wit filter:



SHT45 without filter:



I am busy making SHT35 and SHT45 probes with filters that meet the 20um test standards.
Have a nice day.
