    77== Project Setup
    88
    9 On the transmission side, connect your signal generator to your antenna and choose a frequency of your choice (901 MHz default).
     9On the transmission side, connect your signal generator to your antenna and choose a frequency of your choice (901 MHz default). We found that -20dBm worked best for us (with ranges of 1-2 meters)
    1010
    11 For the reflector
     11For the reflector, upload either the ADC_Temp or ADC_Temp_Max file on the MSP430 board. Connect the MSP430 ground to the reference ground of the device you want to probe, and the MSP430 P1.0 pin to the voltage that you are probing. A PWM signal is then generated on P2.0, which should be connected to an ADG902BRMZ (or similar RF transistor) which is connected to a 900MHz antenna.

    13 On the receiving side, hook up your RTL-SDR to your computer then run the Matlab script with the corresponding toolkits (Communications, RTL-SDR, etc.). Remember to change the center frequency in the script (default 901 MHz). The script should run with a periodogram and a output of detected frequency. There is a commented out section for temperature conversion that may or may not be accurate.
