A device includes a bus interface to couple to a shared bus of a sensor network. The device also includes a sensor interface to couple to a sensor of the sensor network. The device further includes a gated pulse width modulation circuit coupled to the bus interface and to the sensor interface. The gated pulse width modulation circuit is configured to transmit, during a time slot determined based on a timing signal received via the shared bus, an analog pulse width modulated representation of a signal received from the sensor.
