Greenhouse temperature control is a key factor which affects crop growth, and the traditional way of temperature regulation already cannot satisfy the requirements of modern greenhouse: high precision, rapid acquisition and response. The 32-bit EasyARM1138 single chip microcomputer is taken as the main control chip to implement multiple canopy temperature acquisition and control. AT89C52 single chip microcomputer is applied as assisted control chip to implement single greenhouse temperature control. DS18B20 digital temperature sensor is used to collect temperature information in the greenhouse. Through buttons, LCD monitor, GPRS SMS alarm module, and light alarm system with LED and buzzer sound to realize human-computer interaction. Through analyzing of the present condition of greenhouse environment, greenhouse temperature parameters are adjusted to achieve the requirements of crops growth and cultivation development to provide the most suitable temperature environment for crop growth, and increase crop yield and quality.
