Microwave sensors

Microwave working principle

— these sensors operate in the microwave radio range similar to a radar: the device periodically emits a pulse and, by analyzing the reflected signal, determines the presence of foreign objects in the controlled space. Such devices are somewhat more complicated and more expensive than infrared ones, but their capabilities are noticeably wider. For example, an IR sensor usually has a limited field of view, while a microwave device is able to "see" the entire 360° around. The "radar" coverage area is not limited to line of sight, it can detect foreign objects behind small obstacles — like window glass or partitions between workstations in an office. In addition, the microwave sensor is equally effective over the entire temperature range. Among the disadvantages, in addition to cost, it can be noted that it is undesirable to use them when people are constantly in the microwave area. However, most alarms still turn on only when there are no people in the room.
