If your sensor is sending serial data you don't need an ADC channel you need to connect it to a serial input on the telosb and use the UART components to read data. UART0 is available on the 10 pin I/O header at: pin 2 UART0RX UART0 receive PORT35 pin 4 UART0TX UART0 transmit PORT34 pin 9 AVss Analog ground
Search for use examples. I haven't used it myself.
