Distance is possibly an issue if the wiring to logger isn’t short. For the enclosure application, I thought about dropping a small teensyLC in the base with TTL/RS232 interface so that a serial connection could be made from enclosure to logger. Teensy would handle all the sensor data requests and then just feed a csv over TTL or RS232 depending on application.

Thoughts?

These are all 3.3V I2C sensors.

I’m not sure if the questions regarding the 4-20mA circuit would be sufficed by something like this?

Steve, when I first read your comment I was a little confused. I haven’t used the stalker board before, but I was under the impression that it was a ATmega2560 and not a 328P. I couldn’t figure out why you had code constraints…….

I spoke offline with Steve Hicks about the 2560 logger board I had done. If the community thought it would be useful I could redesign that to be more useful to this community and make it available. I would just need to know what the most prominent portions of the stalker or other board needed to be implemented and what the size constraints might be if any.

By the way, as far as enclosures go. I’ve had great luck, even when it comes to customization using TEKO, PacTec and Polycase.

neihl,
This device wouldn’t be used in a weather balloon type environment, that’s just one of the areas I deal in most with NWS. I have a side business where I currently only sell NOAA Weather Radio / SAME Decoder modules for arduino and raspberry pi usage and wanted to expand my device offerings. I won’t post the site, cause that’s not really my intent to joining this group. I really just enjoy sharing ideas and experiences when it comes to using arduino with real world sensor devices. If someone is interested they can ask.

I see this more as a datalogger sensor addition, but would really like a way to build it into a probe that would fit into an aspirated or unaspirated type enclosure. I’m sure I could just make it available as is for those who might want to integrate how they see fit.

libraries would be set up on GitHub. I need to start making that the standard since that is where everything is going these days. My radio files were just posted on my website for download, but those most likely need to be moved as well.

How well does you LiPo hold up under extreme cold? What is you data transmission rate? I know in the one I’m working on for NWS I’ve had to put the 2560 and the Xbee 900HP to sleep when not in use to conserve power. We are looking at a 7.2aH SLA battery with solar and regulator.

Great place for more Arduino tutorials here as well:
