Bumping this because it was my motivation to switch my temp/hum over to the SHT75...
I had the SHT75 lying around for almost a year. I finally got the time to solder a 4-pin connector to an old temp/hum cord I had lying around. I lathered it up with some silicone conformal coating and then plugged the SHT75 into the socket.
I didn't have a lot of daylight to play with, but I wanted to test it anyways. The end result is I'm beyond impressed. The response is miles ahead of my old Davis temp/hum sensor. I have a 9V-12V fan in my FARS and I'm getting a lot of movement on the readings...even at night. One thing I didn't expect was for the sensor to report all tenth temp values...even in degF. The Davis sensor I had installed was one of the older analog ones and it skipped some values...i.e. 66.9,67.1,67.3,67.4,67.6, etc. This one reports all missing values in between. Obviously that's not overly important considering the accuracy of the sensor, but it always annoyed me that some values were skipped. I'm not sure if the Davis SHT11 ones skip any or not.
The only thing I didn't have time for tonight was to install a SF1 filter. The more I thought about it, the more I wondered if I could bypass the sensor filter and instead purchase an equivalent filter to install at the opening of my FARS. The SF1 specs state that the filter material is PTFE with polyester scrim. Has anyone ever tried anything like that? I'd assume I have enough torque and CFMs on my fan at 12V to pull plenty of air through a filter at the bottom of my FARS.
Just curious what you all think,
