基于ATmega328的农业监测系统设计与实现

Design and Implementation of Agricultural Monitoring Systembased on ATmega328Abstract:With the rapid development of science and technology,the field of agriculture also began toconnect with the Internet.With the help of ATmega328 MCU development equipment and Internet ofthings technology,an agricultural monitoring system is designed.Through the development of Arduinoequipment and sensors,the agricultural monitoring system can monitor the environmental factorsneeded for the growth of crops,such as the air temperature and humidity of the surroundingenvironment,the intensity of the light received by the crops,the soil humidity of the growing soil andother data in real time,so as to realize the full recognition of the production information of crops.Thedata can be transmitted After the sensor is collected,it is sent to ATmega328 single chip microcomputer,and then further data judgment processing is carried out,and then the data is reflected to the userthrough the corresponding module to realize the intelligent management of agricultural production.The agricultural monitoring system is mainly developed by Arduino UNO Rev3 developmentboard with ATmega328 single chip microcomputer as CPU with the aid of Arduino IDE developmentplatform.DHT11 temperature and humidity sensor is used to collect the real-time temperature andhumidity data of the surrounding environment of crops,which is presented to the users of theagricultural monitoring system on the 1602 LCD screen.Using photosensitive resistance,soil moisturesensor and raindrop inspection sensor to monitor the illuminance,soil water shortage and weatherwhether it rains,RGB LED three-color lights express different environmental conditions by flashingdifferent color lights.Mq-2 smoke gas sensor is used to monitor whether there is harmful gas in the air.When there is harmful gas in the air,the buzzer will send out a sound to remind the user.Keywords:Arduino,Sensor,ATmega328
