Web2 days ago · Active Detectors. Active motion sensors are also known as radar-based motion sensors. They emit radio waves or microwaves across a room or other area, which strike on nearby objects and reflect it to the sensor detector. When an object moves in motion sensor-controlled space at this time, the sensor looks for a frequency shift in the returning ... WebHeat Detection Sensors. Some motion detection technology utilizes sensors to detect heat differences. If the sensor detects a sudden change in temperature, like, say, a body, crossing in front of it, the lights will flip on. This type of motion sensor would be best utilized for an indoor motion detector light instead of an outdoor one.
