Abstract:

In order to reduce the complexity in wiring when measuring the temperature and humidity of the complex environment, the wireless sensor networks solution based on ZigBee agreement is introduced, using JN5139-Z01-M01 as the chip of measurement subsystem, and using the SHT15 sensor to measure the temperature and humidity and transfer the measured data to the network harmony equipment, which uses the JN5139-Z01-M02 as the chip. The network harmony equipment sends the data to the computer and accomplishes the monitoring of temperature and humidity and store the experimental data，and memory the experimental data simultaneously. In order to make corresponding adjustments in time, the data processing software is developed by Visual C++ 6.0, which can monitor the running states of all measurement subsystems in realtime.The experiment results show that the system goes well. And it can get the accuracy temperature and humidity in strong interference.  And compared to traditional wired measurements, a good solution to the convenience of communication and measurement problems.

Key words: ZigBee protocol, temperature and humidity, JN5139 chip, Visual C++ 6.0
