Moreover it’s inefficient, labor-intensive, and wastes human resources. Therefore, for raising the level of automation of the temperature and humidity and light intensity control, this paper designs a circuit of using detection sensor and microprocessor technology to achieve a control of some greenhouse temperature, humidity and light intensity, and discusses the circuit design of hardware and software programming process. High temperature, light automatically turns down shading networks and opens fan, low-temperature, luminance hours shading automatically rolls up networks and opens the heating valves, humidity-hour automatically opens spray head, and the temperature humidity and light intensity can be controlled in setting the context for flowers, seedlings provide the appropriate temperature, humidity and light. It realizes the control of temperature and humidity and light intensity, and raises the automatic level of someone greenhouse control.
