I don't understand why you are using the Arduino for sensors. The DS18B20 used a one wire interface. There are one wire to USB and Serial adaptors available an you can even bit bang it on a printer port if you need to. Am I missing something you are using the Arduino for?


Hi David, We didn't plan just for onewire initially. We were also using Humdity, vibration, light etc and we thought putting a micro-controller in there makes sense. I agree with you on directly interfacing DS18B20 into serial port


Simplicity maybe? Sometimes it's just worth it to save the extra time needed.

I also once connected an Arduino to a Raspberry Pi just because I was more confident in using the Arduino than wiring directly to the board.

Vivek thank you for the answer. It makes sense.
How did you solve the issue of the mast colliding. Do you just not worry about it or do you nave contact sensors on the mast?
I am sure you have thought of making one that uses just an Arduino and an XBee, wifi shield, or hackable wifi router for communications.
Or just using a wifi router with a powered USB hub as the controller. You would have to build a battery pack for them which could be a pain. Or you could use an Android cell phone with USB OTG for IO

This project seems very similar to one described by IBM researchers, with two papers dating back to 2011

I'm wondering if the two groups are working in parallel, or if you know each other?


Nice, except for pretentious music in the video !
