Use of BS at low temperatures.
Archiver
Posts: 46,084
I have been using BS1 and BS2's for quite some time, but now have a
potential application that may require operation below the BS1's
"official" rated temperature range of 0-70C. My experience with other
electronics has been that while clocks and A/D references may drift a
little out of spec, many "0-70" microcontrollers still chug along quite
nicely at -10 or even -20C. Does anyone out there have any experience
with cold BS1's? Weather stations, freezer monitors, etc? Any advice
appreciated, and no lawyer will call if my mileage varies from yours :-)

deg C just fine. After the balloon carrying them busrts, the wind chill
drops their temperature to something like -10 deg C for tens of minutes.
I've not had one fail for those short term exposures.

In my application, where we send BS2's to 100,000 feet, they operate at 0
deg C just fine.· After the balloon carrying them busrts, the wind chill
drops their temperature to something like -10 deg C for tens of minutes.
I've not had one fail for those short term exposures.

as low as -20 deg C. The big enemy is moisture. Be sure to use a
well sealed box and lots of fresh desiccant. Also a power source that
can supply the needed current at that temperature, and solar panels
at a steep angle so as not to accumulate snow etc etc. (your milage
may vary!)
