Design of Greenhouse Temperature and Light Intensity Control Circuit

In view of domestic scientific and technological achievements at present, real-time control circuit for greenhouse temperature and light intensity has been designed in line with the principle of cost saving and easy control. With advanced temperature sensor and light sensor applied to measure the temperature and light intensity, an execution unit is controlled by single-chip microcomputer (SCM) to regulate the temperature and light intensity, creating a hardware design scheme and software design idea. In case of high temperature and high light intensity in greenhouse, the sunshade net will be put down and the blower will be started automatically; and in case of low temperature and light intensity, the sunshade net will be folded up and the heating valve will be turned up automatically. In this way, the temperature and light intensity in greenhouse will be controlled within the designed range.
