Design of Monitor-and-control System for Supermarket Fresh Area based on Zigbee.

Abstract􀃼According to the status that most of supermarkets
can’t effectively monitor the temperature and humidity around
food of fresh area in our country Currently, the thesis designs a
hierarchical topology central monitoring system based on ZigBee
wireless sensor network(WSN).In the system, the temperature
and humidity of surveyed area can be automatically monitored
and controlled. The monitoring nodes, with the CC2430 chip and
THS11, can collect and upload temperature and humidity data to
the Management Centre, which displays and processes the
data ,through the central node and the RS-232 interface. If the
collected data exceeds the threshold, it automatically starts the
alarm system and the regulating system; while the data is lower
than the standard value, regulating system could be
automatically shut down. Nodes work in the regular query power
saving mode. Power is obtained from button cells conversion
through MAX687.The results reveal that this WSN system has
the potential for field applications due to its low cost, low power
and flexible networking construction.
