Take control of your security with motion sensors. Microwave Sensors and PIR's are two of the leading technologies on the motion sensor market. They can help provide you with increased autonomy and security throughout your home, garden or office, whilst helping to cut down your energy bills at the same time.

With the ever increasing popularity of motion detection technology an influx of new products have hit the market all with unique and exciting capabilities. We thought that we would give you an insight into the motion sensor market to help give you decide which products are right for you. We're really excited about motion sensor products and think that you should be too 

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 PIR Sensor?

PIR sensors make fantastic security lights. Working using heat detection gives PIR Sensors an added specificity to their detection. Focusing on detecting body heat means that there is a decreased chance of false triggers occurring, making you feel more safe and secure in your home. Alongside this comes low levels of energy consumption, keeping your energy bills low and saving you money. With reliable detection throughout both day and night, a PIR sensor is fantastic option if you're in the market for a motion sensor.

  • Decreased chance of false triggers
  • more energy efficient
  • cheap

How does a Microwave Sensor work?

In contrast, Microwave Sensors emit microwave signals throughout their detection range. The sensor is triggered by timing how how long these signals take to return to the sensor, referred to as "echo time". This allows a microwaves sensor to have highly sensitive detection throughout their range whilst having the ability to cover an extremely wide area of detection, perfect for large open spaces, making them fantastic options as LED Floodlights

What are the advantages of a Microwave Sensor?

A Microwave sensor is extremely sensitive across a large detection field. This sensitivity gives microwave sensors a distinct advantage as security lights. They detect very fine motion and cannot be tricked or avoided in the way that other sensors can. The added advantage of Microwave Sensors is the ability for microwaves to travel through materials, this includes glass, plastic and thin wall, giving another layer of sensitivity, activating due to the presence of vehicles, perfect for your driveway. A microwave sensor will give you added confidence in your home security. When combined with the extra long-life expectancy of a microwave sensor you can save yourself money 

  • Extremely sensitive
  • detects through glass, plastic and thin walls 
  • Perfect for security lights
  • Extra long life
  • Strong, long lasting construction, higher IP and IK ratings

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.

  • Security light
  • Hallways
  • Walkways
  • Above doors

Where can I use a Microwave Sensor?

You can use a  microwave sensors  throughout multiple environments, they are extremely well suited to outdoor usage often possessing extremely high IP and IK ratings due to having integrated microwave sensors so you can rest assured of their longevity. Used throughout Driveways, secured spaces, gardens, large open spaces or throughout office spaces, to help control your energy usage. A microwave sensor light can be extremely effective as a security light or for usage in Floodlights providing extremely sensitive detection over a large area. A Microwave Sensor has some drawbacks, having the ability to pass microwaves through glass, plastic and thin walls means you have to be selective with where you place your sensor, we wouldn't recommend hanging it facing your conservatory! 

  • Garden light
  • Driveway
  • Home Security
  • Large Open Spaces

PIR or Microwave Sensor?

Our Verdict

If you're shopping on a budget, our recommendation would be a PIR sensor, low energy usage, cheaper initial purchase price makes a PIR sensor an extremely appealing option, especially when combined with the reliable performance of the 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.

 If you're looking to make a purchase of a microwave sensor, we have the range of products to fulfil your needs including Microwave Sensor, Security Light or Batten lights, we would recommend our Philips LED Floodlights range, fitted with integrated Microwave Sensors, they are reliable microwave sensor lights with an extra long life-expectancy.

We also stock a large range of PIR products, including PIR Sensors , PIR floodlights, ideal options for increased automation and security around your home or workplace. We would recommend our JCC LED Flood Lights range, which includes a wide range of Pir Sensor floodlights at fantastic prices.
