There are two main types of motion detection sensors available, microwave and PIR (Passive Infrared) and we’re here to take a quick look at the pros and cons of each. pir These sensors detect heat.
Microwave sensors are active devices that detect movement using a principle known as the ‘Doppler Effect’. Once installed, microwave sensors continuously emit low-level microwave signals across a designated space or ‘detection area’.
Instead of detecting heat signatures, a microwave sensor sends out invisible microwaves throughout their detection wave, and measures how long it takes these waves to return to the sensor. This is a process known as Echo Time.
Aug 31, 2021 · Microwave motion sensors do have a consistent capability of detecting movements in all temperatures. They provide the perfect lighting conditions in any extreme environment and help occupants with the perfect moment along with improved safety.
Mar 18, 2022 · Compare the Benefits of Microwave & PIR sensors for the security lighting of your home, garden & office. Discover the best method of motion detector lighting.
Oct 10, 2022 · A microwave sensor is an electromagnetic radiation motion-detecting device. They emit electromagnetic waves with the help of a transmitter that is then reflected back to the sensor. The receiver in the sensor then analyzes the echo time of the waves that are bounced back.
