Claim 0:
1. A digital-display control apparatus for garbage can with adjustable sensing distance, comprising:
an emitter;
a receiver;
an amplifier;
an analog to digital converter;
an analog to digital conversion result register connected to the receiver via the amplifier and the analog to digital converter;
a comparison unit;
an adjustable sensing distance register;
a microcomputer control unit, wherein outputs of the analog to digital conversion result register and the adiustable sensing distance register are respectively connected to the comparison unit, wherein control ports of the microcomputer control unit are respectively connected with the analog to digital conversion result register, the comparison unit, the adiustable sensing distance register, and the emitter;
a drive circuit, wherein one output of the microcomputer control unit is connected to the drive circuit;
a digital displayer; and
at least one key, wherein an input of the at least one key is connected with the microcomputer control unit, wherein an output of the microcomputer control unit is connected to the digital displayer, wherein a signal input by the at least one key is processed by the microcomputer control unit, and a sensing distance value is obtained as a register value of the adjustable sensing distance register, wherein one of the sensing distance value and a digital information representing the sensing distance value is outputted to the digital displayer by the microcomputer control unit for display.
