Hi to all, I'm trying to guess how to get temperature in Celsius degrees from Telosb Mote (using SensirionSht11C). Looking around I found three different methods to calculate this value and I don't know which one is the best:
1) temp= -40 + 0.01 * data; // from TinyOS (said by http://www.eecs.iu-bremen.de/wiki/index.php/TinyOS) 2) temp= -38.4 + 0.0098 * data; // from datasheets (said by http://www.eecs.iu-bremen.de/wiki/index.php/TinyOS) 3) temp = -39.4 + 0.01 * data; // from TinyOS mailing list (http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2006-July/018154.html) What should I consider? And another question: the ADC converter of the Telosb has a resolution of 12 bits, but temperature readings can be taken at 8, 12 and 14 bits. Are they really made at 12 bits and then converted or are they made at 14 bits but considering only the first 12 bits? Best regards, Flavio Posta, news, sport, oroscopo: tutto in una sola pagina.
