The wireless temperature and humidity monitoring system

To meet the requirement of humidity and temperature monitoring,a point-to-multipoint wireless humidity and temperature sensor network was designed.The hardware circuit of monitoring system is composed of the wireless transceiver module nRF2401-the basic circuit of the lower computer,and the 51 MCU and the humidity and temperature sensor.The upper computer,which is developed with Visual C 6.0,can display the monitoring results with dynamic curve,and store and print the monitoring results.Through software testing by the upper computer,the system was proved to run stably and have good practicability.Besides,this design also has good portability and a wide range of application in the warehouse system,power system,database,tobacco and food processing industries.
