Temperature and humidity control system convenient to monitor in real time and suitable for greenhouse

A temperature and humidity control system convenient to monitor in real time and suitable for a greenhouse comprises a data acquisition device and an upper computer, wherein the data acquisition device is arranged in the greenhouse and the upper computer is arranged in a monitoring center. The data acquisition device comprises temperature and humidity sensors, a temperature and humidity regulating device and a microprocessor, wherein the temperature and humidity sensors are arranged at data acquisition points in the greenhouse and used for acquiring temperature and humidity in real time, and the temperature and humidity regulating device is used for regulating the temperature and humidity of each acquisition point. The microprocessor is respectively connected with the temperature and humidity sensors and the temperature and humidity regulating device and transmits information acquired by the temperature and humidity sensors to the upper computer through serial port communication, the upper computer feeds the received information back to a liquid crystal display screen arranged in the monitoring center, and control instructions of the upper computer are used for controlling the temperature and humidity regulating device through the microprocessor so that the temperature and humidity in the greenhouse can be regulated. The temperature and humidity control system convenient to monitor in real time and suitable for the greenhouse can reflect temperature and humidity changes in the greenhouse in real time and regulate the temperature and humidity of the greenhouse according to the temperature and humidity changes.
