A PIR sensor, or a passive infrared sensor, is an electronic device that can detect motion in its vicinity.
They are essential components in many security systems, and they’re widely used in homes, offices, and public spaces.
When it comes to choosing the sensor that’s right for you, the number of options on the market can make it a daunting task, but fear not! We’re here to help.
In this article, we will review some of the best PIR sensors available in the UK.

QWYEURO Adjustable PIR Motion Sensor
- Brand - QWYEURO
- Dimensions - 15 x 8.8 x 3 cm
- Weight - 175 g
- Range - 12m
- Special Feature - Flush Fitting
Next we have the QWYEURO Adjustable PIR Motion Sensor. It’s currently selling for £13/$16 on Amazon.
QEYEURO have opted to use high-quality switches that are specially designed for the home. This means that the detector is triggered when people arrive and automatically deactivates when they walk off, greatly reducing energy waste.
It’s also highly adjustable. You can change the sensitivity setting between low sensitivity for a detection distance of 2m or high sensitivity for a detection distance of 12m. This makes it really versatile, allowing you to use it in a variety of applications.
This sensor is also capable of detection in ambient light less than 10LUX when it is adjusted on the “moon” position. This makes it perfectly capable of detecting movement at night.
If you’re looking for a highly adjustable PIR sensor at a reasonable price this sensor might be the one for you.

Lepro Outdoor PIR Sensor with Security Light
- Brand - Lepro
- Dimensions - 21.2 x 23.7 x 4.7 cm
- Weight - 840 g
- Range - 10m
- Special Feature - Security Light
Another great PIR sensor is the Lepro Outdoor PIR Sensor with Security Light. It’s currently selling for £31/$37 on Amazon.
This device from Lepro is a PIR sensor combined with a security light, and it’s perfect for outdoor use.
It’s made of die-cast aluminium casing and tempered glass with a protection grade of IP65. The device is rust-proof and surface-treated with high-quality electrostatic adsorption, making it perfect for use in a garden or courtyard.
The included 50W LED flood light generates a saving of more than 85% when compared to a traditional 350W incandescent light bulb. This makes the combined Lepro light and sensor both convenient and cost effective.
Lepro’s PIR sensor is highly adjustable as well. The sensing distance, sensing angle direction, sensing time and illumination can be manually set and adjusted. This makes the system extremely versatile with a wide range of application.
If you’re in the market for a PIR sensor and accompanying security light, look no further than this device from Lepro.

Steinel IS 140-2 PIR Motion Sensor
- Brand - Steinel
- Dimensions - 7 x 8.6 x 9.5 cm
- Weight - 170 g
- Range - 14m
- Special Feature - 140 Degree Angle
Next we have the Steinel IS 140-2 PIR Motion Sensor. It’s currently selling for £37/$46 on Amazon.
As you would expect from a Steinel sensor, the IS 140-2 is really impressive.
It has a long range of 14m (the longest range of any sensor on this list) and a detection angle of 140°. The optical system can swivel 180° and tilt up to 90° for exact adjustment of the detection zone. The detection zone can then be customised even further using the shrouds provided.
The use of innovative spherical Fresnel lenses allows this sensor to detect people with greater precision than many of it’s closest competitors. This in combination with the high level of customisation allows you to create an extremely reliable detection system.
Similarly to some of the other sensors on this list, the 140-2 has an automatic turn off setting. You can adjust the sensor to turn off between 8 seconds and 35 minutes after a detection, ensuring that you have the ideal balance of safety and energy efficiency.
If you’re looking for a highly customisable sensor from a respected brand, the 140-2 from Steinel is an ideal choice.

FAQs
When selecting a PIR sensor for home security, some of the most important factors are the detection range and sensitivity – these determine how your sensor will detect potential threats, so it’s critical to look for a system with sufficient range for your home and ideally adjustable sensitivity.
For outdoor use, ensure that your system is weatherproof and can withstand UK weather conditions. If you search for outdoor PIR sensors, or select from the models on this list, this shouldn’t be an issue.
Compatibility with existing alarm systems or smart home setups can also enhance the functionality of your sensor. For example, compatibility with a traditional alarm system could allow your sensor to trigger an audible alarm or even alert the authorities of a potential intruder.
Lastly, look for energy-efficient models to reduce energy costs. Most modern models should be fairly efficient, but it’s always worth shopping for one that will keep costs to a minimum.
PIR sensors are generally straightforward to install, especially for basic models. Most sensors will come with mounting brackets or adhesive options for easy installation on a wall or ceiling. Some systems may need require some wiring, but there are many battery-operated models available. After your sensor is on your wall and ceiling and wired if necessary, you may need to adjust some basic setting like trigger range or sensitivity. This is usually easily done and well described by the manufacturer’s setup instructions.
PIR motion sensors are a great way to protect your home from intruders and improve your peace of mind. If you choose the right model, they’re energy efficient, easy to install, and can deter potential threats without any involvement from the homeowner.
