Hi,
We would like to use Sense Hat Raspberry Pi shield for our High Altitude Balloon mission. We were planning to use Sense Hat as outside temperature and pressure sensor, and an Arduino for internal temperature, measuring the temperature inside the casing. Hence we want to use it for outside temperature it should be outside the case, but the temperature is too cold for raspberry to be outside. So is there a way to connect in different ways rather than use pins, such as connecting cables to the pins or something else for expanding the connection to outside of casing?
Re: High Altitude Ballon Sense Hat Shield
My recommendation is to use a DS18B20 1-wire temperature sensor outside the payload, with something to shade it from direct radiation from the sun (otherwise it will heat up). This device is directly supported by Raspbian (enable it in raspi-config) and requires very little code to read the temperature.
For pressure, so long as you haven't completely sealed the payload (which is bad anyway - it'll probably explode in the near vacuum of near-space!) then internal and external pressures will be almost identical during ascent. I'd just make a hole in the payload wall somewhere near the Sense hat.
