20090717· Two types of sensor technologies often are applied to a location to reduce false alarms, prevent defeat techniques, or fill unique needs. The combination of microwave and passive infrared sensors is a popular example of applying dual technologies (see Figure 717).Reporting can be designed so an alarm is signaled when both sensors detect an intrusion (to reduce false alarms) or when either ...

20180911· Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. That may mean it triggers an alarm, notifies authorities, or maybe turns on a floodlight. IR radiation ...

From a constructional standpoint, light level sensors can be either standalone devices or they can be integrated with a microwave or passive infrared occupancy sensor into a single unit.
