摘　　要：通过以SD02型热释电传感器等器件组成的红外感应模块,将检测到的人体信号传送给以STC89C52单片机为核心的单片机模块;单片机模块根据设定程序检测前级送入信号,并作出判断输出电信号控制后级驱动模块;驱动模块采用SH-215B高性能细分驱动器,其输出控制电机运行。Body signal detected through an infrared sensing module consisting of some devices such as SD02 pyroelectrie sensor is transmitted to the a microcontroller module using STC89C52 MCU as the control centrol. The signal is detected by the micro- controller module according to a setting program and a electrical signal is output to control drive module SH-215B behind which controls the motor.
