Design of temperature and light-intensity control system for solar intelligent greenhouse

A solar intelligent greenhouse with the temperature and light-intensity control function is designed, which is based on the intelligent concept for agriculture. The control system is composed of a general framework of the greenhouse, a solar power supply module, a light-intensity control module and a temperature control module. The light-intensity control module includes shutters, an optical sensor, a single chip microcomputer(SCM) control circuit and a stepping motor. By detecting the light-intensity, the SCM control circuit controls the stepping motor to rotate the shutters, and the light-intensity can be controlled accordingly. And the temperature control module can also adjust the temperature. This solar intelligent greenhouse is based on our own design with the advantages of the relevant greenhouse, and it can automatically control the greenhouse's light-intensity and temperature according to the external conditions. It has outstanding advantages including simple structure, simplicity of operation, energ
