Wanted to follow up with the results of my initial test. I attempted powering the fan using external power from the CAT-5E cable. The fan powered up and I was able to read all of the sensors except the barometer disappeared. Unplug the fan and the barometer came back. I could have spent some...

I wanted to know if it is acceptable to run a small fan for a FARS from the external power on the 1-Wire CAT-5 cable. The external power is provided from the power supply for my Hobby Boards barometer. The fan is a small computer fan that runs off of 12VDC and draws approximately 0.08A. I...

Since the electrician's putty was the only change I had made to the station, I tried removing it this morning. The humidity reading dropped like a stone. It went down from 127% to 80% in just a couple of hours. It was raining outside and the humidty was around 80-85%. I'm now reading at 60%...

The actual relative humidity when those readings were taken was around 70%. Later it went up to 80% and I was reading 127%. My readings have stayed at or above 100% for two days now with it reading 127% for about 24 hours. The highest the true humidity reached was around 80-85%. So I am...

Eric, Everything is daisy chained, and I run external power from the barometer board. I have a DS9097U, followed by the barometer located indoors. Outside I have the humidity/temp board located in a homemade radiation shield, along with a separate solar board located on top of the radiation...

I have a 1-wire weather station with an AAG anemomemter, Rainwise rain gauge converted to 1-wire, and hobby boards temperature/humidity, solar, lightning, and barometer boards. Everything was working fine and my data uploaded to CWOP was looking good. One day recently my software was unable to...

I suspected that I had the caps installed backwards (I built the kit myself, so that was always a possibility). I tripled checked, and even emailed Eric to make sure I had them installed correctly. It turned out that they were installed correctly. They don't get really hot, but they are...

I was experiencing my temp/humidity/solar board registering elevated temperatures when I supplied it with external power. Withoput external power the temperature readings were fine. But I ended up needing external power to get reliable 1-Wire sensor readings. I did some research/testing and...

It was the DS18S20, although now that you mention it, the humidity reading was affected as well. I was only using the temp reading from the DS2438 as part of the humidity calculation and not looking at it separately. After looking at the schematic, I see what you mean about the DS18S20 being...

Looks like my registration and reply got removed in last nights site move. I just re-registered and will repeat my post that got lost. I have the same problem as well. I have been bench testing my weather station inside before installing it permanently outside. So far I have a TAI8515, Hobby...
