Pages: [1] 2 3 4. For my first RF project, I'm attempting to capture and decode MHz RF signals received from a remote Thermo-Hygrometer sensor in order to perform some home automation at various temperature and humidity levels.

Signal Screen Captures: I couldn't make out the signal traces on my screen, but with long and short pulse you are on the right track. Temporarily assign 1 and 0 to one or the other and compare the patterns you see with the numbers you know are being transmitted. There is probably a preamble, a device ID, some data coded as either binary or binary coded decimal, and a checksum of some sort. There are lots of examples on the web of similar transmissions that have been successfully decoded.

Thank you for the encouragement jremington; I feel a little better having someone tell me that I'm on the right track. I have performed a great deal of research, testing, sampling, and analyzing before posting here. As you noted there are a lot of great resources for decoding weather station signals and RF signals in general.

You can see the repetition in the following: When comparing multiple RF transmissions, one can see that the first 32 bits, in red below, never change… this I assume is the preamble, device id, unused data fields, and possibly a check sum.

The temperature values are from to degrees F, again I believe requiring a minimum of 7-bits for a total of bits to transmit both humidity and temperature. None of the signals are shorter than bits so this is feasible… but no matter how I flip the bits or the order I read them I am not able to decode This is what causes me to suspect that I may be interpreting the signal incorrectly Decoding that signal may not be easy, but it is an interesting challenge.

It is very helpful to compare signals that differ by the minimum possible number of bits. For example, if you could compare several signals reporting exactly the same humidity, but minimal variations in temperature of for example Also, if you can capture a temperature of exactly 0.

Another useful piece of information is how a presumed checksum usually one byte, but I've seen a 4-bit checksum varies with any change in the message. If the message changes by exactly one bit, but many checksum bits change, then it is probably a CRC type of checksum.

If only one checksum bit changes when one message bit changes, it is probably a simple sum. I have documented this in these two postings where source code plus comments! The signal frame's timing was similar but the data structures were quite different.

While you can find a host of brand-name stations for sale through their website, the company also sells its own line of weather instruments on Amazon. Ambient Weather is most notably renowned for consistently finding the perfect balance between features and affordability within their lineup of weather stations. Their latest model, the WSB, lives up to those same expectations. We were pleasantly surprised to see the weather station do so well in terms of accuracy when compared to the Davis stations arguably the gold standard in personal weather stations.

It measures all the weather data most of us would ever need—inside and outside temperature and humidity, barometric pressure, rainfall, wind speed and direction, plus UV and solar radiation.

One thing that makes all this possible is the excellent directions. After setting up many of these, I can tell you at times it can be a pain.

I was pleasantly surprised to see the WSB weather station hold up so well against the Vantage Vue, however, expect a little more variability in terms of accuracy. Temperature and humidity readings were ever so slightly off from the Vantage Vue, and winds were reasonably accurate.

Rainfall readings also seemed to vary further from our Vantage Vue station and true conditions. At this price point, these accuracy variations from the higher-end stations should be expected.
