Introduction of Related Design System for Temperature and Humidity Monitor
There is a ZigBee terminal node module at each point to be measured in the greenhouse, and the module is composed of a temperature and humidity sensor SHT15 and a ZigBee terminal node. The temperature and humidity monitor collects the temperature and humidity data in the greenhouse through the temperature and humidity acquisition module, and then transmits the data to the ZigBee terminal node through the serial port. The collected data is sent to the ZigBee coordinator responsible for establishing the network through the ZigBee protocol. The data is collected and transmitted to the PC through the serial port. After receiving the data from the coordinator, the PC is processed and finally displays the temperature and humidity data and collection point information in a visual interface.
The hardware part of the system consists of: ZigBee terminal node module, temperature and humidity sensor SHT15 and ZigBee coordinator module. The ZigBee core board is a basic circuit that CC2430 implements the wireless transceiver function for the controller. In order to facilitate debugging and reduce the interference of the antenna Chen Sheng during wireless transmission and reception, the CC2430 chip and the peripheral basic circuit are separately made in the design. CC2430 chip integrates 8051 single-chip microcomputer, CC2430RF transceiver, 8kb RAM and flash memory. The temperature and humidity sensor SHT15 used in the system outputs the temperature and humidity data in digital signal mode, so CC2430 can directly control the temperature and humidity data in the greenhouse. Collect and process it and send it to the ZigBee Coordinator.
The temperature and humidity monitoring system lower-level control sensor collects the temperature and humidity data of each prediction point and sends the data to the upper computer after wireless processing. In data acquisition, each point takes multiple measurements during temperature and humidity data collection, collects seven sets of data, removes the maximum and minimum values ​​during data processing, and averages the remaining five sets of data. The de-averaging average filtering method can remove accidental errors generated during the collection, and further improve the accuracy of the temperature and humidity data collection.
With the rapid development of the Internet of Things, agricultural production will inevitably usher in the modernization revolution. Temperature and humidity monitor temperature and humidity sensor SHT15 monitor the temperature and humidity in the greenhouse, effectively improve the measurement accuracy; use zigbee for wireless data transmission to enhance the stability and timeliness of data transmission; LabVIEW software to write real-time monitoring interface Increased agricultural production efficiency. The entire system is designed with low cost, high flexibility, and high reliability. It has a broad application prospect and is suitable for large-scale promotion in modern agricultural production.
