A microwave sensor is a motion detection device that uses microwave radiation to detect movement within a designated area. It operates similarly to radar systems, emitting electromagnetic waves (microwaves) and measuring the reflection of those waves when they hit an object or person. Microwave sensors are highly sensitive and can detect motion over larger areas and even through obstacles, such as thin walls or doors. This makes them an ideal choice for a variety of commercial, industrial, and residential applications.
Microwave sensors are also known for their ability to detect very small environmental changes, making them more accurate than other sensor types, such as PIR (Passive Infrared) sensors.
Microwave sensors work by emitting a continuous stream of microwave pulses, which bounce off objects in their path. These sensors use a process called Doppler shift to detect motion. When the emitted microwaves encounter a moving object, the frequency of the reflected waves changes slightly. The sensor detects this change and triggers an action, such as turning on a light, activating an alarm, or notifying a system.
The primary benefit of microwave sensors is their ability to detect motion through obstructions. Unlike PIR sensors, which only detect infrared radiation from living beings and are blocked by physical barriers, microwave sensors can detect objects or people even if they are hidden behind walls or furniture. This makes microwave sensors more versatile and reliable in a variety of environments.
At Sensinova, we offer a wide range of microwave motion sensors designed to meet the unique needs of different applications. Here’s an overview of some of our most popular models:
The Nova PFC-S Dry Contact Sensor uses 5.8 GHz microwave technology for precise motion detection, activating automation systems with its dry contact output. With a 360° detection range, adjustable sensitivity, and time delay, it’s ideal for automation in commercial spaces. Its compact design and IP20 protection make installing and integrating it into indoor systems easy.
Microwave sensors are highly effective at detecting motion with greater sensitivity and range compared to other sensors. They offer numerous advantages, including the ability to detect motion through obstacles, longer detection ranges, and higher accuracy in complex environments. With Sensinova’s range of microwave sensors, you can improve energy efficiency, and automate systems in both residential and commercial spaces. These sensors are ideal for lighting, and industrial applications, providing a reliable and cost-effective solution for smart living.
Microwave motion sensors detect movement and automate systems like lighting, and air conditioners in residential and commercial spaces. They are ideal for high-traffic areas or places where motion needs to be detected through barriers.
Yes, microwave motion sensors are completely safe. They emit low levels of microwave radiation, which are non-ionizing and well within safe limits for human exposure.
Unlike PIR sensors, which detect heat, microwave sensors detect movement by measuring the reflection of microwave pulses. They do not rely on temperature changes, making them more sensitive and effective in detecting movement through obstacles.
Microwave motion sensors are commonly used in automated lighting, industrial machinery monitoring, and home automation systems. They are also useful in large spaces such as parking lots, corridors, and warehouses where detection needs to cover a wide area.
