Hi,
Great subject; I really like this kind of detailed discussion about a good subject... Thanks for the work writing the library.
Tim, one of the sensors we were talking about has a built-in temperature sensor: This one: http://goo.gl/Ox2rP
This is the one that has both UART mode and Pulse/echo mode. The temperature measurement only works in UART mode.. The docs I have say:
---------------------( COPY )--------------------------
Temperature function only in UART mode. TX send 0X50 trigger temperature measurement. When temperature measurement is completed, the module will return a byte temperature ( tDATA ), The actual temperature is tDATA-45 . For example, by TX sending 0X50 , RX received 0x45 , then the temperature at this time is [69 ( 0x45 to 10 decimal value) -45] = 24 degrees C
-----------------( END COPY )----------------------
Of course temperature can be measured with a DS18B20, or etc also...
Maybe you can actually do temp compensation?? Maybe only important for OutdoorBots...
Sensors should be there in 2 or 3 days...
