I'm looking to repurpose an RF430FRL152HEVM to measure the resistance change in flex sensor that has a nominal resistance of 200k. My thought was that I could remove the thermistor at R3 here 
I've written custom android app to read the data from Block 9 for ADC0, 1, and 2. I'd like to keep the results from the light sensor, so without disturbing the results, what would be the best way to go about inserting the sensor in order to get a semi-accurate result. Currently I've removed the thermistor and added a wire on the right side while using the breakout on the HEVM board for the left. I have the sensor attached between the two.
