1. A communication system comprising:
a node configured to collect ambient data with a sensor; and
a docking station configured to couple to the node and to establish a communication path with the node through only one signal along one or two wires,
wherein the node includes,
a first module configured to use a first data communication protocol for receiving commands from the docking station along the communication path, and
a second module configured to use a second data communication protocol for sending the ambient data to the docking station along the communication path,
wherein the first data communication protocol is different from the second data communication protocol, the first data communication protocol is asynchronous and the second data communication protocol is a modified synchronous protocol,
wherein the first data communication protocol is a Universal Asynchronous Receiver/Transmitter, UART, protocol, and the second data communication protocol is a Serial Peripheral Interface, SPI, protocol
wherein the second module is an SPI module that is modified to not transmit a clock signal to the docking station,
wherein the SPI module is configured to not send a chipselect signal to the docking station; and
wherein the node includes a legacy microcontroller, which is not configured to implement USB high speed, 100Mbits Ethernet MAC or WiFi protocols.
