A transponder communicate information on a physical condition to a remote location, without the need for a lo- cal power supply or any wire or optical communications with the remote location, by detecting the physical condition and encoding information on the condition into a reprogram- mable portion of the transponder memory for transmission in response to an interrogation signal. The encoder is pref- erably formed from an oscillator that provides an output signal whose frequency is a function of the information provided by the detector, and a counter that accumulates a count which is a function of the oscillator frequency, with the counter programming the memory in accordance with its accumulated count. A variable capacitor, resistor or in- ductor is preferably used to detect the physical condition and vary the oscillator's output frequency. A bubble wrap- type variable capacitor is particularly useful for monitor- ing the quantity of air within a tire.
