Office Environment Monitoring System Based On CC2530

As China’s national economic development and raising the level of science andtechnology, especially computer technology, communications technology, the rapiddevelopment of control technology, network technology and IT, the growingrequirements of life, study, office environment, safety, comfort. Large-scale integratedunit, enterprise, or the school office, on the one hand, the need for staff to provide ahighly secure, comfortable, convenient internal environment, on the other hand, needto use a variety of modern scientific and technological means, the greatest degree ofreduction of energy waste, improve operational efficient, timely discover andeliminate all kinds of failure.To meet this demand, the design office set based on the CC2530wirelessenvironmental monitoring system. Within the office environment the system canreal-time monitoring of temperature, humidity, light conditions, and personnelmonitoring, these data can be more reasonable energy distribution, and reduce waste.For example, during the hot summer, some offices need to turn on air conditioning toreduce the room temperature about25℃temperature to meet the needs of people, ifthe room temperature is too low, not only a waste of electricity, not appropriate forhuman health can be monitored through this system at room temperature, effective toprevent this phenomenon; in after work, if you forget to turn off office lights, lightinformation according to the monitoring of this system, it can be immediatelyidentified.The monitoring system based on the the CC2530measurement node, relay node,the master node and host computer. The CC2530is TI has introduced a complete2.4GHz RF on-chip system solutions, it is suitable for a wide range of applications.CC2530combined with a fully integrated, high-performance RF transceiver with an8051microprocessor, to8KB the RAM,32/64/128/256KB flash, and other supportfunctions and peripherals. Measurement node in the office on the basis of the CC2530is equipped with a DB130-10digital temperature and humidity sensors, digital opticalintensity sensor integrated circuit in BH1750FVI and HC-SR501human body sensing module8051CC2530internal microprocessor control, and environmental datacollection, and through the relay node to the form of wireless data is finally sent to themaster node. Development of each node program in C language in Keil uVision3environment, the master node to connect with the host computer and the PC softwarebased on Microsoft Visual Basic6.0platform to develop, for the observation ofenvironmental data.The experiments show that the system is stable, reliable, and can basically meetthe requirements of the office of the environmental parameters monitoring functions.
