The sensor has been tested out and is working properly. Now, it needs to be modified such that all sensors will be interrogated simulataneously. THis can be done by cutting all lines leading to the common output and soldering

Sensor modified by cutting common output and resoldered by Santhana Balal. Tested and working properly. Without grounded padding. Oscillation is roughly 1 Mhz
