A greenhouse temperature measurement and control circuit was designed and simulated on Proteus. In the circuit,the single chip microcomputer AT89C52 controlled digital temperature sensor DS18B20 for real-time greenhouse temperature detection,and displayed the working temperature reference value and real-time detection temperature on LCD1602. Meanwhile,it controlled the greenhouse temperature in real-time according to temperature range control theory so as to guarantee the greenhouse crop growth in the appropriate temperature range. The circuit is intelligent and economical,stable and reliable with simple installation,high measurement precision and strong anti-jamming,which has many applications.
