Intelligent dustbin and its automatic switch method

Abstract

The invention discloses an intelligent garbage can and an automatic opening and closing method thereof. The intelligent garbage can comprises a can body and a can cover hinged to the can body. The intelligent garbage can is characterized in that the intelligent garbage can further comprises a human body infrared sensor, a microwave sensor, a microprocessor and an opening and closing module which are arranged on the can cover and electrically connected in sequence; the microprocessor starts the microwave sensor when detecting the human body through the human body infrared sensor in a first monitoring area; when the microprocessor detects a target meeting first instruction movement in a second monitoring area through the microwave sensor, the opening and closing module controls the can cover to be opened; when the microprocessor detects a target meeting second instruction movement in the second monitoring area through the microwave sensor, the opening and closing module controls the can cover to be closed. The garbage can can be opened and closed according to the gesture of a person through the microwave sensor, spurious triggering is reduced, and the intelligent garbage can is convenient to use by people, completely intelligent and capable of saving electricity.

Description

technical field [0001] The invention relates to the field of smart home, more specifically, to an intelligent trash can using a microwave sensor and an automatic switching method thereof. Background technique [0002] As the concept of home intelligence is increasingly recognized among consumers, traditional household appliances, especially non-contact sensor security systems, are undergoing unprecedented changes in many aspects. Compared with the emerging Internet of Things system, there are currently common security systems on the market based on voice control, passive infrared pyroelectric sensing and light blocking switches, active microwave sensing, and three detections that combine the above-mentioned technologies. On the premise that ultra-remote remote control or complex command interaction is required, it has obvious advantages in ease of installation and cost. Among them, the sensor based on the principle of active microwave Doppler sensing is widely favored by us...
