TinyOS Oscilloscope Application for Temperature Reading #158

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I am using Oscilloscope application to read temperature from SensirionSht11 on 
TelosB Mote. I am getting a long data like 

00 FF 00 02 0A 00 93 00 00 01 00 00 02 00 00 19 1B 

Why i am getting too long data ?  I just need a temperature reading in Decimal 
Value.

you always get raw data with the sensors in hex values. the last 4 digits are 
what you ask for. convert 191B hex to dec and then use the formula

temp in celsius=-39.6+0.01*hextodec
