But a microwave motion sensor in a dual-tech motion detector will work through glass, as microwave sensors are able to detect motion through solid objects. For this reason, care must be taken to adjust the microwave portion of the sensor properly during installation.
How does a microwave occupancy sensor work?
A Microwave sensor uses high frequency radio waves operating at 360 degrees. They work in a similar way to radar, working on changes in the reflected radio waves. They are especially effective in Large areas such as Warehouses monitoring any changes in the return waves and responding immediately.
Where can I use a PIR Sensor?
PIR sensors are fantastic for usage in more enclosed areas. Hallways, front doors, office spaces and walkways are perfect locations for PIR sensors, a reliable option as a sensor for motion activated lights whilst also having the capability to be used as effective and reliable Security lights. However, PIR sensors can be limited by the climate, making their placement extremely important, away from the elements and out of direct heat allows for the best result. Another potential drawback for PIR sensors is the IP and IK ratings are commonly lower, due to the PIR being external to the product in most cases, this means that the sensor is commonly not as strong and resilient as a microwave sensor product, though with the correct placement these issues can be avoided.
How does a PIR Sensor work?
Through detecting Infrared radiation, a PIR sensor detect heat and movement across their detection range. When an object which is radiating heat, such as a person or animal crosses their detection range, the sensor triggers, switching on the attached device, for example an LED Floodlight. Making a PIR Sensor extremely useful for detecting people and helping to add security and automation to devices. We think that they're extremely useful throughout multiple settings such as offices, bathrooms and home security.
What are the advantages of a Microwave Sensor?

PIR sensors make good security lights and are a reliable option, however we think that they are best when used throughout enclosed areas, hallways, walkways, above doors both internal and external, this will allow for them to be used at their full capability and provide excellent automation throughout your home or office. Microwave Sensors are the slightly pricier option, but their performance justifies this cost, their sensors are extremely sensitive and are the best option for home security, this sensitivitiy is partly their downfall with the need for selective positioning and the chance of false triggers. But if your looking at securing your home, garage, office or garden then a microwave sensor floodlight is the perfect option.
What Are Microwave Sensors?
Unlike PIR sensors, microwave sensors work similarly to sonar. These sensors send out constant microwave signals into their environment. They then measure how long it takes for the signal to bounce back to the sensor. When something moves within the detection zone, this disrupts the signal, slightly delaying the amount of time it takes to reach the sensor. The microwave sensor recognises this delay and triggers the light to switch on.
What is a PIR light?
PIR means “passive infrared”. Lights that use PIR sensors, utilise infrared sensors to constantly monitor everything within range. These sensors are generally made up of two small slots. Think of them as “eyes”. When nothing is moving in front of the sensor, the “eyes” pick up the same amount of infrared radiation.
What is motion sensor lighting?
There are several motion-sensitive lights on the market right now, with Martec’s range leading the industry. Motion detecting lights help reduce wasted energy around homes and businesses as they turn off when no one is around . Motion sensitive lights are also great security, especially for homeowners. And security lights are more important now than ever before. However, many people don’t realise there are two different kinds of motion detection options on the market. And they both work in very different ways. By knowing the difference between PIR sensors and microwave sensors, you can make the right choice when looking for new lighting. Today we are going to discuss the difference between microwave and PIR sensors, as well as the benefits of motion sensor lighting.
What are motion detecting lights?
Of course, the most common use for motion detecting and sensitive lights is as security lights. They are installed in gardens and entryways for homeowners. They’re also common in car parks and building sites. These floodlights can light up as soon as they detect motion. This not only provides security, and helps prevent people from creeping around your home, it also improves safety. No more fumbling around in the dark, trying to find steps or fumble with light switches when carrying bags and armfuls of groceries.
Is a PIR sensor better than a microwave?
PIR sensors are neither objectively better or worse than microwave sensors. Both sensor types have their own advantages and are better for different spaces and tasks. Lights that feature PIR sensors are generally best for use as security lights. They only pick up movement from living things, meaning they will give fewer false alarms. On the other hand, microwave sensors can be adjusted to only pick up movement from human-sized movement from human-sized objects, however this is generally done in the factor before the sensors are installed in the lights.
Do PIR lights work on animals?
PIR sensor s only detect heat signatures, so they aren’t usually triggered by inanimate objects being blown across their field of view. This not only makes them good security light, they won’t trigger whenever a leaf blows across a path or a branch moves in the wind. They will trigger for animals and wildlife, though, so that is something to consider if you have pets.
Is a PIR light good for garden?
For garden and home security, a PIR sensor light is far more efficient and effective.
What is a PIR sensor?
PIR sensor houses pyro-electric sensor as shown in the figure-2. PIR sensor generates energy when exposed to heat. Human or animal body radiates energy in the form of infrared radiation. Hence when human/animal come in the range of PIR motion sensor, it receives thermal energy and hence motion is detected by the sensor.
Is a PIR sensor passive or active?
Microwave sensor is active sensor as it emits microwave signal for detection. PIR sensor is passive sensor as it senses infrared signal emitted by various objects including human body.
Can you install a microwave sensor and a PIR sensor?
Conclusion: The best results are achieved by installing both microwave sensor and PIR sensor to leverage advantages of both the sensors.
How far can a PIR sensor be used?
Advertised distance up to 90', although real world will be typically under 40'. PIR sensors are more limited in real world use than microwave.
What is a microwave sensor?
A microwave sensor is a electro-magnetic radiation motion-detecting devices that may be used to operate luminaires. Microwaves work differently from PIR sensors in that they send out microwave waves that radiate off different surfaces and return to a sensor in the detector. The sensor can identify any movement within its range by analyzing this data, and it can do it in less than a 1/5 of a second. Better versions of these operate in the 5.8ghz band giving them better range and low interference,
What is a motion sensor light?

In recent years, motion sensors have evolved to be more accurate and even programmable by remote control. In addition, some of the motion sensors are now wireless. Wireless sensors are simple to install, but do require regular battery changes as well as complicated controls or apps to integrate. You are generally better off with a solid reliable motion sensor light that does not need much babysitting
What is a PIR light?
The abbreviation PIR stands for "passive infrared." Infrared sensors are used in PIR lights to continually monitor everything within range. In most cases, these sensors are made up of two tiny slots.
What is the best outdoor security light?
PIR-sensing lights are often the best choice for outdoor security lighting. Because they only detect movement from live objects, they are less likely to cause false alarms. On the other hand, microwave sensors can be configured to only detect movement from human-sized things, although this is usually done before the sensors are put in the lights.
How does a sensor light differ from a voice control?
It differs from voice control or other sensor lights in that it does not require sound, which eliminates the problem of voice control noise, and because it is a switch that detects body heat, which prevents the loss of invalid power .
Can a microwave detect a person moving?
More sophisticated microwave sensors can identify whether a person is traveling towards or away from the sensor or moving randomly. Even trained professionals may not be able to move in such a way as to escape being detected by a motion sensor. This makes them ideal for industrial applications such as LED motion sensor flood lights and other building perimeter application.
