A,
I still can't believe how small some of these devices on your WeatherMote are. The Si7021 is making me realize how much I need glasses! Almost 50 and feeling it. Thank you. I'll definitely be moving away from the DHT22. Your board was perfect for me. I liked the BMP085 too. When I started all this I was looking for commonly used sensors that work easily with the Arduino. I wish I had thought more of power consumption when I started all this knowing I wanted to run on battery power. I really like the footprint of the Si7021 over the DHT22 too. But I would never have been able to get that chip on the board.
Is there a schematic to the R3 board? And do you have a direct link to your OSH files? I see you have set up a voltage divider circuit, and was interested in giving that a go.
I am really liking the Ds18b20s and they will work perfect for me to monitor temperatures within my Aquaponics system. I'm thinking of having 11 three pin headers all connected in parallel. One to connect to your weathermote, and the others for DS18b20s Also thinking of using a simple micro to allow mapping based on position on this board, rather than by ID numbers of the DS18b20s. Postion 1 temp, position 2 temp, etc,.. I don't want to have to change my code if I have to change out one of the sensors. Just change out the sensor, and I'm done. I was thinking of mimicking the DS18b20s on the 1 wire bus with simplified ids of 0 through 9. And make it so the whole thing could be plugged in like a single DS18b20.
Keep up the good work.
And Yes I am using a Raspberry PI as my gateway. Almost ready for prime time. I haven't gone live online yet. Been testing the database and webpages. Not sure how it will deal with public access. Perhaps not even a good idea.
