Design of intelligent voice dustbin based on single chip microcomputer

Intelligent voice trash can based on STC89C52RC microcontroller. The design takes STC89C52RC as the control core, and focuses on the detection module of ultrasonic sensor and photoelectric sensor for human body or objects. The HC-SR04 sensor is used to detect the presence of human body, and the RPR220 sensor is used to detect the presence of objects. In this way, the motor module is respectively controlled to automatically open and close the dustbin lid and the voice alarm module to issue the prompt sound. Use timer to dustbin interior at the same time gush to scatter disinfectant. The use of photosensitive sensor at night, when the detection brightness is less than the set value, provide automatic lighting. The design makes further improvement and innovation on the original intelligent dustbin system, which is more safe and convenient and intelligent.
