Environmental monitoring system based on infrared communication
Based on some scenes,such as greenhouse or nursery,which need to collect real-time environ-mental information intermittently,and the problems of inconvenient and high error rate of manually collected environmental information,therefore,an environmental monitoring system based on infrared communication is studied.The system uses STC89C52 microcontroller as the control core,and is mainly composed of infra-red transceiver module,temperature and humidity sensor,buzzer,button,LCD1602 display screen and other external modules.It adopts the common NEC infrared communication protocol.The system can realize data acquisition,modulation and demodulation,infrared communication,data display,alarm and other functions,which can help people better view environmental information.The experiment verifies that the system has low cost,stable communication,real-time transmission and strong anti-interference ability.
