PCB For Raspberry Pi WH1080 Weather Station
Previously I wrote about using a Raspberry Pi to receive 433MHz signals from a WH1080 weather station. This is the mess of wiring I came up with:
This worked fine until it stopped. I probably didn’t crimp a wire properly and too many knocks resulted in unreliable operation. To solve this I designed a PCB that connects the radio receiver, pressure sensor and an antenna to a Raspberry Pi:
The design is very simple:
It accepts a surface-mount version of the RMF01 module (the version with a black resin blob). This is easily soldered onto the PCB by hand.
A female through-hole SMA connector is used for the antenna connection. This allows a range of off-the-shelf antennas to be used. The one I purchased from eBay didn’t work so I modified it as can be seen in the pictures. Alternatively a wire can be directly soldered to the board.
Finally a six pin BMP085 module is connected to a header. The pinout of the BMP085 module used is:
- Pin 1 = 3.3V
- Pin 2 = SDA
- Pin 3 = SCL
- Pin 4 = No connection
- Pin 5 = No connection
- Pin 6 = Ground
Here is how the PCB looks when populated:

I have some spare boards, so if you would like one to experiment with please contact me.
Update: All the spare boards are gone. I hope everyone who received one has a lot of fun with them!

That is because of this: “connect to gmail.de[74.125.237.214]:25: Connection timed out”. I will resend but it won’t work if Google doesn’t figure out their problem. š

Hello Andy, I’ve received your board some days ago and I’m playing with it, now š
I’ve tried with an 868mhz sma antenna I bought, but it does not work (like yours, I think).
A simple wire connected to the pin seems working better…
How have you modified your antenna to get it working ?
Thank you !

I removed the rubber sheath from the antenna by cutting it down the side and peeling back.
I soldered a 17cm solid-core wire to the end of the spiral wire.
I covered the wire and the join in heat-shrink tubing.
No idea why I needed to do this. Perhaps the input impedance circuit on the RFM01 is poorly designed…

Hi I have a number of the boards, most of which are surplus to my needs. If I can cover the cost of manufacture and postage I am more than happy to get them out to anybody who is interested.

Hello,
I’m also interested to get one š At the moment I connected RPi to the weather station via USB, but it’s not ideal (and does not look pretty). Thank you!
