【摘要】 热释电红外传感器因其独特的对活动人体的检测能力,已经在节能和安防领域得到广泛应用。将热释电红外传感器应用于公共场所的灯控装置中:以单片机为控制核心,采用光敏传感器采集环境光强参数,热释电红外传感器检测有无人员在受控范围内活动,根据环境光强和人员活动情况自动决定灯泡点亮和熄灭状态,从而达到节约电能的效果。更多还原

【Abstract】 With its unique testing capability of active body,pyroelectric infrared(PIR)sensor has been used widely in energy saving and security.PIR sensor was used in public light control device.Taking SCM as the controlling core,the set used photosensitive sensor to collect luminous intensity parameter and PIR to test human activity with the controlled scope.It turned on or turned off lights automatically according to light intensity and human activity,thus saving the energy.更多还原
