Abstract
Based on the Z-Stack protocol Stack, with the CC2530 radio frequency transceiver chip and DHT22 digital temperature and humidity sensor as the core, this article puts forward a new implementation designed for the wireless temperature and humidity acquisition system on the basis of the Zigbee wireless communication technology. With the method of upper machine software by GUI, changes in temperature and humidity can be shown on the display terminal intuitively. The article mainly expounds the system structure design, temperature andhumiditydataacquisitionprocessandgraphicalinterfacemonitoringimplementation. Experimentsshowthat the wireless sensor system can make the real-time data acquisition of temperature and humidity, which has not only good efficiency and scalability, but also high reliability and excellent stability.
Highlights
With the rapid development of electronic technology, computer technology, and communication technology, the Internet of Things technology arises at the historic moment
This work is mainly based on ZigBee wireless sensor network technology, with the RF(Radio Frequency) transceiver CC2530 chip as the core, and TI (Texas Instruments) company’s Z-Stack protocol stack, a self-organizing network for wireless temperature and humidity monitoring is constructed
2.1 Z-Stack protocol stack Z-Stack protocol stack is a ZigBee protocol stack developed by TI company, it has been accepted by the ZigBee Alliance and widely adopted by many developers around the world
Summary
With the rapid development of electronic technology, computer technology, and communication technology, the Internet of Things technology arises at the historic moment. The research and application of Bluetooth, GPRS, WIFI, ZigBee, and other wireless sensor network technologies have promoted the rapid development of new generation sensor network technology. After collecting and receiving the data, it communicates through the serial port and uploads it to the upper computer to display the real-time monitoring situation in a GUI manner. The advantage of this system is that it can use ZigBee wireless networking to access a large number of data collection point sensors. It has stable performance and can be widely applied in the
