When shopping for a new LED flood light, knowing the difference between PIR and microwave sensors can help you make the best decision.

A microwave sensor is a motion detection device for electromagnetic radiation that can be used to operate light fixtures. Microwave and PIR sensors work differently because they emit microwaves that radiate from different surfaces and return to the sensor in the detector. The sensor can analyze this data to identify any movement within its range, and it can be done in less than 1/5 of a second. These better versions operate on the 5.8ghz band, offering better range and lower interference,

More sophisticated microwave sensors can identify whether a person is approaching or moving away from the sensor, or moving randomly. Even a trained professional may not be able to move in a way that evades detection by motion sensors. This makes them ideal for industrial applications such as LED motion sensor floodlights and other building perimeter applications.

Several advantages of using microwave sensors:

1) Microwave detectors can be used in almost any environment, including environments that would otherwise be detrimental to the sensor, such as high-temperature conditions that could damage the photoelectric sensor. As such, they are one of the most adaptable sensor systems available.

2) Microwave sensors will reduce the number of false positives without reducing the number of accurate positives, increasing accuracy while enhancing the simplicity of use.

3) Microwave detectors can penetrate walls and holes. As such, they may cover a wider home or commercial area, including considerable outdoor space. Therefore, they are often used by people who need to protect a large amount of property.

4) The microwave sensor can be set to continuously sense motion so it won't shut down in a busy warehouse.
