Example Embodiment
[0029] Embodiment 1: as Figure 1-12 As shown, a temperature and humidity monitoring system for vegetable greenhouses based on ZigBee, including temperature and humidity sensors, light intensity sensors, soil humidity sensors, ZigBee wireless communication modules, host computer, main controller, water pumps, ventilation fans;
[0030] The output end of the temperature and humidity sensor, the output end of the light intensity sensor, and the output end of the soil humidity sensor are respectively connected to the input end of the main controller. The main controller is connected to the upper computer through the ZigBee wireless communication module. connect. The upper computer is a PC human-computer interaction system and uses MSComm control to complete the monitoring design, and can set two different adjustment modes: automatic adjustment and manual adjustment.

The invention discloses a ZigBee-based vegetable greenhouse temperature and humidity monitoring system and method and belongs to the technical field of agricultural production. The system comprises atemperature and humidity sensor, a light intensity sensor, a soil moisture sensor, a ZigBee wireless communication module, an upper computer, a main controller, a water pump and a ventilating fan. Themethod is characterized in that, to begin with, standard ranges are set in the upper computer; then, the sensors collect and monitor the internal environment parameters of each greenhouse; the main controller sends the data to the upper computer through the ZigBee wireless communication module; the upper computer compares the currently-received data with the set standard ranges, and then, sends afeedback instruction to the main controller; and the main controller drives the water pump and the ventilating fan to operate. The system and method can monitor the environment parameters of temperature and humidity, illumination and soil humidity in the greenhouse through the sensors in real time, and can drive the water pump and the ventilating fan to work to enable the temperature and humidity, illumination and soil humidity in the greenhouse to reach the set standard ranges respectively through the main controller according to the monitored data.
Description
technical field [0001] The invention relates to a temperature and humidity monitoring system and method for vegetable greenhouses based on ZigBee, belonging to the technical field of agricultural production. Background technique [0002] In the existing technology, if the traditional vegetable greenhouses need to detect the temperature, humidity and light conditions, they must rely on manual detection and inspection, which not only increases the work intensity of agricultural personnel, but also causes problems of measurement accuracy and untimely measurement. It is impossible to timely and effectively control the environmental index in the vegetable greenhouse. Contents of the invention [0003] The present invention provides a ZigBee-based vegetable greenhouse temperature and humidity monitoring system and method to realize real-time monitoring and adjustment of temperature and humidity, light and soil humidity environment parameters in the vegetable greenhouse.
