Motion and light sensors

Motion sensors are electronic devices used to detect physical movement in a specific area. They are widely used in a variety of places, especially in conjunction with light fixtures, both at home and in commercial spaces.

Motion sensors can operate on different principles, depending on the type of technology. The most popular of these are:

  • PIR (passive infrared): Detect changes in the level of infrared radiation. When a person or animal enters the sensor’s range, the heat emitted by the body causes a change in the level of radiation detected by the sensor.
  • Microwave: They use radio waves to detect movement. They emit a wave that bounces off objects and returns to the sensor. Movement within the sensor changes the frequency of the reflected wave.

Light sensors monitor ambient lighting and turn on the device if the light falls below a preset threshold.

1. Energy savings

Motion sensors in light fixtures automatically turn on lights when they detect presence, and turn them off when there is no movement. In this way, significantly reduce electricity consumption, as the light shines only when it is needed.

Since the lights are turned on only when needed, the life of the of the bulbs is longer, reducing replacement and maintenance costs.

Energy savings also translate into a reduced carbon footprint, which is good for the environment.

2. Sensitivity and coverage

Sensors can have different ranges and sensitivities that can be tailored to specific needs. The most common parameters that sensors can adjust or check are:

  • exposure time – determines how long the lamp will shine when motion is detected,
  • range sensitivity – determines the distance at which motion is detected,
  • sensitivity to ambient light – it checks the light level and turns on the sensor only from a predefined threshold, so that the lamp will only turn on only after darkness falls.

3 Safety

Automatically turning on lights when motion is detected increases security, as areas such as hallways, stairways, garages or garden paths are illuminated when needed. This reduces the risk of tripping or falling in the dark.

The light turning on when motion is detected can deter potential intruders, making it an effective tool in security systems security systems.

4. Convenience

The user does not have to remember to turn the light on and off, which is especially useful in rooms that are rarely visited or where lights are often forgotten to be turned off (such as in basements or warehouses).

Infrared detection

PIR sensors

PIR sensors, work by detecting the level of radiation infrared radiation (heat) emitted by objects within their range. They are sensitive to changes in temperature, so they can detect the presence of people or animals.

PIR sensors operate passively, i.e. they do not send out any kind of radiation or waves; instead, they passively “listen” for changes in the infrared radiation in their environment.

They have a specific detection range, which can fluctuate depending on the model. They also have a specific angle of view, which determines how wide a field their detection can cover. It is possible to adjust the sensitivity to minimize the risk of false alarms. You can also set the length of time the device will be active when motion is detected.

Because they detect changes in heat, they are less prone to false alarms caused by external factors, such as the movement of tree branches or small animals, compared to some other types of motion sensors. Due to heat detection, PIR sensors do not work through walls or behind obstacles.

PIR sensors may not function properly in extreme temperature conditions, and may be less effective when an object moves directly toward or away from the sensor instead of through its field of view.

PIR sensors are typically inexpensive and offer an effective, cost-efficient method of motion detection.

Microwave sensors

MIC sensors

Microwave sensors, also known as radar sensors, operate on the principle of Doppler radar. They emit microwave waves that bounce off objects within their range. Movement of an object causes a change in the frequency of the reflected waves, which is detected by the sensor as motion.

Penetration through obstacles: One of the main advantages of microwave sensors is their ability to penetrate certain materials, such as walls, doors and glass surfaces. This means that they can detect motion even when the object is not directly in their field of view.

They usually have a longer detection range compared to PIR sensors, allowing them to monitor larger areas.

These sensors are highly sensitive, allowing them to detect even small movements. However, this feature can lead to more false alarms, especially in outdoor environments, where movement of trees or other objects can be misinterpreted as the movement of people.

Resistance to environmental conditions: microwave sensors are less sensitive to changes in environmental conditions, such as temperature or lighting, compared to PIR sensors.

As with PIR sensors, microwave sensors have a specific range and angle of detection, which can be adjusted to meet the specific needs of the application needs. It is possible to adjust parameters such as sensitivity or alarm duration, which allows for better control over their operation.

MIC microwave sensors are highly effective in detecting motion, offering a wider detection range and the ability to penetrate through some obstacles. Their high sensitivity and resistance to changes in environmental conditions make them an excellent choice for applications where reliability and accuracy of motion detection are a priority. However, these features must be weighed against a potentially higher cost and higher energy consumption. Microwave sensors are therefore ideal in situations where these aspects are acceptable in terms of overall system requirements.

Dusk sensor

SENSO DAYLIGHT

The SENSO DAYLIGHT sensor monitors ambient brightness and, below a preset threshold, turns on the selected device. This way we can be sure that the lamps we choose will shine only after darkness falls. The SENSO DAYLIGHT sensor can also be combined with PIR or MIC motion sensors, expanding their capabilities.
