Description
The system, called smart monitoring station, is a handheld device which works as the hub for low data rate wireless network based on ZigBee® protocol to which all the nodes (smart monitoring nodes - STEVAL-IFS015V1) are connected. This system measures the temperature, humidity and light intensity and gathers information of various sensors (temperature, humidity, light intensity and MEMS) from nodes placed at different locations. It can also configure the alarm thresholds for the parameters of all the connected nodes, as well as for itself. Lights (or any other AC load) connected to nodes may be controlled through the smart monitoring station with addition of a few components and its status is available on the smart monitoring station display. The system has a user interface with the graphic menu, color TFT display (240 x 320) and touchscreen. Data logging and analysis of logged data can be done using the GUI developed for this system. This demonstration board can be powered up using 3.7 V Li-ion battery. Alternatively it can work with USB power without battery. When the battery is mounted, the same USB charges the battery and operates the system. STEVAL-IFS014V1
