Design and application of environmental protection intelligent garbage can based on MCU
Aiming at the problem that the user is easy to contact the bacteria in the trash can,the Arduino UNO is designed as the electronic control core.The intelligent trash can measures the distance between the object and the cover through the infrared tube sen-sor.When it senses that there is an object approaching within 30cm,it sends a signal to control the rotation of the steering gear and au-tomatically opens the cover;After the barrel cover is automatically closed,the main control chip can drive the atomizing sheet to spray the disinfectant for sterilization and disinfection;the ultrasonic ranging sensor on the top of the barrel can monitor the height of the gar-bage in real time,and when the barrel is almost full,the ultrasonic ranging sensor can give an alarm through a buzzer to remind a user to clean the garbage in time;and the main control chip can drive the atomizing sheet to spray the disinfectant for sterilization and disin-fection.Due to the design of the mechanical structure,the user can automatically close the mouth and change the bag by pressing the button of the garbage can when cleaning up the garbage.The results show that the spread of bacteria is effectively inhibited through the realization of various functions,and the use process is convenient and fast.
