1. A device, comprising:

  • a sensor element for collecting sensor data;

    a connector configured for coupling to a connector interface exposed by a sensor network node having a wireless transceiver for wireless communication with a gateway device at a monitored location; and

    a first controller that communicates with a second controller in the sensor network node, including;

    a first pin for device select signaling between the device and the sensor network node,a second pin for receiving a first series of clock signals that are transmitted from the sensor network node after receipt by the device of a device selection signal via the first pin, and for receiving a second series of clock signals that are transmitted from the sensor network node when the sensor network node receives data from the device,a third pin for bi-directional communication of data between the device and the sensor network node using clock signals received via the second pin, the first controller in the device receiving a request for data from the sensor network node via the third pin using the first series of clock signals received via the second pin, and the first controller transmitting the requested data to the sensor network node via the third pin using the second series of dock signal received via the second pin, anda fourth pin for availability signaling between the device and the sensor network node, the device signaling an availability of the requested data to the sensor network node by transmitting an availability signal to the sensor network node via the fourth pin, wherein the transmission of the availability signal to the sensor network node causes the sensor network node to transmit the second series of clock signals to the device via the second pin, and wherein the first pin, second pin, third pin, and fourth pin of the first controller are coupled to respective pins supported by the connector;

    wherein the first controller transmits a request poll signal to the sensor network node via the first pin prior to the receipt by the device of the device selection signal, wherein the device selection signal is produced in response to the request poll signal.
