An environment monitoring system based on AT89S52 is designed, whose working principle and designing method are introduced.The photoresistor,digital temperature sensor DS18B20 and humidity sensor consist of environment parameter detecting circuit,which are processed by MCU,and then displayed by LCD. Meanwhile,4×4 matrix keys are used to set environment parameter range,and alarming will occur to remind intervention control when out of the range.The experiment shows that the environment monitoring functions of the system are achieved and the result is very good.The system can apply on household appliances, agricultural greenhouse and so on.
