Microcontroller-based greenhouse temperature and humidity control system design
Greenhouse temperature and humidity are important environmental conditions, crop growth, it is not only a direct impact on crop growth and economic benefits, and changes in temperature and humidity can also induce the movement of water plants. People need to control temperature and humidity of the greenhouse, so that it remains within a certain range. Adopted on SCM to control the greenhouse temperature and humidity, not only easy to control, simple, flexibility, etc., and can greatly improve the technical indicators and temperature and humidity, which greatly increase crop quality.
Temperature and humidity control system, the temperature of the surrounding environment through the air humidity testing, the output through the liquid crystal display, and through the SCM measurement of temperature and humidity sensors to analyze the data, the output control signal to start the control system, control air-conditioning and ventilation system, and the parameters MCU control panel. Ultimate realization of the automatic control greenhouse.
Keywords: Greenhouse; temperature and humidity; SCM; sensor
