摘  要:
A control system of agricultural greenhouse was designed based on Atmegal16L single chip microcomputer(SCM) and Siemens S7-300 PLC.The system employed DHT11 as temperature and humidity sensors and SCM as data collecting and processing system.After the collected data was converted by D / A and sent to Siemens S7-300 PLC,the simulation setting and monitoring of operation situation of the system could be realized by touch screen TP177B.The control system had good human-machine interface and high automatic degree,and was simple in operation,thus had good application prospect and wide promotional value.
