Sensor 是传感器的统称，把现实中物理存在的信号转换成电信号。 Switch 是开关的意思，它是被包含在Sensor中的，比如光电开关，它其实就是一种传感器。
An occupancy sensor 1 comprises a passive infrared sensor (PIR sensor) and an infrared sensor (IR sensor) and preferably an ambient temperature sensor, such as a thermistor. The occupancy sensor 1 is configured to confirm occupancy or non-occupancy in dependence on signals measured by both the ...
它们通常被称为PIR,“被动红外”,“热电”或“ IR运动”传感器。 PIR基本上是由热释电传感器制成的(您可以在下面看到,这是圆形金属罐,中心带有矩形晶体) ),它可以检测红外辐射的水平。一切都散发出一些低水平的辐射,而东西越热,发射的辐射就越多。实际上,运动检测器中的传感器分为两半。这样做的原因是我们希望...

The PIR sensor IC consists of 3 pins- Vcc, Ground and Output. In presence of human IR radiations, the sensor detects the radiations and converts it directly to electrical pulses, which is fed to the inverter circuit. The inverter circuit consists of a transistor,which gets into saturation ...
