Design of control system for pet feeder based on single chip microcomputer
Abstract：With the rapid development of social economy and the acceleration of urbanization process, the closure of urban households and the aging of population are becoming increasingly prominent. Based on the needs of people's emotional sustenance and leisure consumption, China's pet industry is also quietly rising. The traditional pet feeding device, can be achieved only designated for food timing feeding, the design is in the traditional timing feeding device on the new wireless transmission function and LCD display function, can make the master in real-time to see pet food intake, guarantee the healthy growth of pet.
This design is the design of wireless intelligent pet food investment based on single chip design is divided into two parts, the first part is the pet food detection and feeding part, which contains the microcontroller module, detection module, and the weight of the motor drive and motor module; the second part is the pet intake display part and an alarm part the main control module, composed of MCU, LCD display, LCD1602 button module, buzzer alarm, data transmission between the master and the slave is through the wireless nRF24L01 module, the amount of food mainly realize the function of real-time detection of pet, can real time designated supplies, while the owner can through the real-time detection of pet liquid crystal margin, ensure healthy pet growth.
