Hello, maybe someone can help me.
I need to use the “unused” pins marked as 2 and 5 in the board. i need to attach another rain gauge, so, how can i configure the source code to enable these pins as interrupts?? or maybe to replace the const int RAIN = 2;, to the pins mentioned above.
thanks for the help.
i tried with the cpp in the .zip of the link on the top, but i got too wrong measures. then i modified the .cpp file to those constants, and i was able to read the pressure correctly.
i don’t know if you have the latest version of the file in the zip, because when the board was new, the readings were accurate, then when i upload the code in the .zip file above, i started to experiment the issues in the accuracy. i’ll very glad if you can confirm if the SFE_BMP085.cpp is the correct file that comes in the board by default.
hi, i had the same problem with the sensor bmp085.
After a long, long investigation, i noticed that the constants in the file SFE_BMP085.cpp are causing the trouble.
i put these constants that worked for me (as an advice, backup the actual constants you have before try it)
AC1 = 8664;
AC2 = -1175;
AC3 = -14551;
AC4 = 34407;
AC5 = 24861;
AC6 = 16892;
VB1 = 5498;
VB2 = 63;
MB = -32768;
MC = -11075;
MD = 2432;
I only have a little problem with the temperature, but as a workaround, i’m using the SHT15 temperature.
ok, thanks a lot for all the help, i’ll do my best.
Thanks for advice Mike, i’ll study the options you gave to me. Only i have one more question: any sensor needs special protection? or are designed for heavy-duty forecasting?
Anyone of you have an example or tutorial of how this board must be deployed, i mean, the correct packaging for outdoors and work properly without damaging the board beause the rain, sun, humidity, etc. thanks a lot.
