| Zusammenfassung: | A circuit 17 for interfacing with a sensor 18 having a sensor input current and a modulated sensor current signal corresponding to a sensed condition. A control module 20 is coupled to the sensor 18 and receives the sensor current signal. The control module 20 converts the sensor current signal to a modulated signal having a pulse width with a duration corresponding to the sensed condition. The control module 20 counts a time corresponding to the pulse width. The time corresponds to the sensed condition. |
