Setting up the hardware
The Z-Wave technology, which is oriented to the residential control and automation market, is designed to be suitable for battery-operated devices. In fact, one of its main goals is to minimize the power consumption. Despite this fact, it provides reliable and low-latency transmission of small data packets at data rates of up to 100 kbps, and a simple yet reliable method to wirelessly manage sensors and control lights and appliances in a house.
For more information on Z-Wave, a good starting point is at https://en.wikipedia.org/wiki/Z-Wave.
In our project, we're going to use a Z-Wave controller on a USB dongle, one slave device powered by the same plug where it's connected to, and one multisensor device that can be powered ...
