All kinds of public and household intelligent trash cans are composed of microcomputer control chips, infrared sensing detection devices and mechanical transmission parts, which are high-tech new products integrating machine and photoelectricity.
When the human hand or object is close to the range of about 30cm of the feeding port, the lid of the garbage can will be automatically opened, and the lid of the can will be automatically closed after 3-4 seconds of garbage input.
Like the automatic sensing lamp, the automatic sensing trash can actually uses the infrared sensing principle, which is automatically controlled through the built-in pyroelectric infrared sensor.
Pyroelectric sensor, also known as human body induction infrared sensor, is the use of temperature change characteristics to detect infrared radiation, often used in life burglar alarm, visitor notification, sensor door, sensor lamp and other fields. Yongxing Sensing can provide you with different kinds of sensors, as well as raw glass and customized filters with high mechanical strength, strong impact resistance and high temperature resistance for tempering, laminating, coating, hollowing and other purposes.
The light collector, also known as the light trash can, is used to collect useless light mainly lasers, and the inner wall is equipped with threads or rough surfaces to prevent multiple reflections, which can prevent stray light in the space to a certain extent, or collect excess light to avoid multiple reflections.
The infrared emission part is an infrared emission tube composed of high-sensitivity semiconductor devices, which is used to radiate the modulated radio wave energy to obtain the position information of the detected object. The radio waves emitted by this transmitter are reflected back when it encounters an obstacle, thus obtaining information about the distance of the detected object.
The receiving element of the sensor part is a photoelectric device composed of sensitive elements such as photodiode array or phototransistor array, which can receive the irradiated energy from the light source and convert it into an electrical signal and output it to the microprocessor for processing as the basis for subsequent work.
With the blessing of the above technologies, the smart trash can can effectively prevent the spread of various infectious diseases through garbage and prevent the overflow of garbage odor in the bin. Technology changes lives!
