设计制作了一种智能台灯，主要是以BISS0001和单片机组成的红外传感控制电路。其特点是在有人时且外界光强较弱时能自动开灯，无人时关灯，节约能源；且能纠正坐姿，防止近视-Intelligent design a table lamp, and is based on single-chip component BISS0001 and infrared sensor control circuit. Its characteristics are in and the outside world when it was relatively weak light intensity can automatically turn on the lights when no one when the lights are turned off, energy conservation can correct posture and prevent myopia
