The 1 nf capacitor is the one being measured.  The output of the 555 goes to the input of a microcontroller which measures the length of the pulse.   T is the length of the pulse in seconds.  R is the value of the resistor used to charge the cap.  The value of the cap is determined by C = T / 1.1 * R
