Why are the values I'm getting through a capacitive sensor decreasing as the resistance gets lower?
Capacitive sensing works by using the RC network created by the resistor (R) and the human body (C) as a timing circuit and measuring how long it takes the analog signal to reach a digital threshold (\$\tau = {k RC}\$) when the capacitance is charged or discharged. When the resistance decreases the timing speeds up, and lower values are measured.
