Greenhouse temperature and humidity monitoring system based on ZigBee transmission

Abstract

The invention relates to the technical field of greenhouse environment monitoring, and specifically relates to a greenhouse temperature and humidity monitoring system based on ZigBee transmission. The system comprises a ZigBee protocol, a PC, and a plurality of data acquisition units, each data acquisition unit comprises a temperature sensor, a humidity sensor, a signal conditioning circuit, a single-chip microcomputer, a liquid crystal display module, an audible and visual alarm circuit, and a ZigBee module, and the single-chip microcomputer is also electrically connected with a button module. According to the system, the monitoring of the greenhouse environment is realized via the plurality of data acquisition units, and incomprehensive detection is avoided; danger early warning is realized by employing the audible and visual alarm circuit so that users can rapidly know the greenhouse environment is abnormal; wireless transmission of signals is realized by employing the ZigBee module so that complicated construction and inconvenient usage brought by wired transmission are avoided; and the system is also advantaged by simple structure, convenient operation, and high practicality.

Description

technical field [0001] The invention relates to the technical field of greenhouse environment monitoring, in particular to a temperature, room temperature and humidity monitoring system based on ZigBee transmission. Background technique [0002] As we all know, crops are the core of my country's agricultural production. With the progress and development of modern science and technology, it is urgently required that China's agriculture move toward intelligent development. The growth and reproduction of any crop requires certain environmental conditions, and temperature and humidity have the greatest impact on the growth of crops. Greenhouse is an important part of modern crop production technology. The control of modern greenhouse is mainly the monitoring of temperature and humidity. However, some backward greenhouse environment monitoring systems have poor stability, low sensitivity and high cost. The temperature and humidity in the greenhouse cannot meet the needs of crops....

Problems solved by technology

Greenhouse is an important part of modern crop production technology. The control of modern greenhouse is mainly the monitoring of temperature and humidity. However, some backward greenhouse environment monitoring systems have poor stability, low sensitivity and high cost. The temperature and humidity in the greenhouse cannot meet the needs of crops. The growth requirements will be extremely unfavorable to its growth, and it no longer meets the development requirements of modern agriculture.
