PIR Sensors

Motion and presence sensors are widely used in lighting systems for offices, industrial halls, and various other types of rooms. They are divided into two main types. The first is a passive sensor using PIR technology. It operates by detecting the temperature of an object through a built-in infrared detector. The sensor turns the light on when it detects a person entering the room. When the person leaves, the light switches off due to the change in ambient temperature. However, it is worth noting that this type of sensor has certain limitations. It is not suitable for rooms where the temperature exceeds 35 degrees Celsius. It may also fail during summer in spaces that heat up significantly. In such cases, the sensor may be unable to detect the temperature difference caused by a human body and therefore may not switch the light on at the appropriate moment. Nevertheless, PIR sensors are much more energy-efficient compared to other types of sensors. They are therefore an excellent solution for office spaces, stairwells, or warehouses where the temperature remains stable.

Microwave Sensors

These are also known as Doppler sensors because they detect movement using the Doppler effect. They emit signals that bounce off people and other moving objects and then return to the sensor. Based on this process, the system determines when the light should be switched on. For microwave sensors to operate effectively, they must continuously emit signals. This means they require constant access to electrical power, which may result in higher operating costs. However, they are the best option when a lighting control system is needed in rooms with very specific conditions, particularly in areas with extremely high or low temperatures. These sensors are also resistant to dust, wind, dirt, and other challenging environmental conditions.

Casambi Control System

A modern approach to lighting control is provided by the Casambi system. It is mainly used in offices, retail stores, and other commercial spaces. It is based on Bluetooth Low Energy technology, which can be operated via smartphones, tablets, and similar devices. The Casambi control system is installed in LED fixtures or modules and is managed using a dedicated application that is completely free and available for both Android and iOS devices. The application is very intuitive, and once installed and properly configured, it provides full access to lighting control. Within the app, users can switch selected fixtures on and off, change light color, saturation, temperature, or adjust dimming levels. To avoid changing settings for each fixture individually, it is also possible to group selected elements together, allowing the same parameters to be applied to multiple fixtures simultaneously.

Light Intensity and Motion Sensors

Installing daylight sensors is an ideal solution when working in changing lighting conditions. Such sensors measure the current light intensity and, depending on the result, dim or brighten the fixtures accordingly. These sensors can be evenly distributed across various areas of an office, hall, warehouse, or store. The sensor reads the data and compares it with predefined values, which may reflect office lighting standards or internal company guidelines. These types of sensors can also detect the presence of people in a specific area. If movement is detected, the system automatically increases light intensity in the designated zone. If no activity is detected and no work is being carried out in a given area, the lighting is dimmed.

Benefits of Implementing Lighting Control Systems

Today, all entrepreneurs are looking for ways to increase savings, and this is entirely understandable. Statistics show that significant savings can be achieved by implementing an appropriate lighting control system. If, in addition, a remote control system via a dedicated application is introduced, users gain continuous access to data indicating electricity consumption. This makes it possible to track which modules consume the most power, draw conclusions, and optimize these costs. It should also be emphasized that lighting control is a modern solution that allows companies to stay up to date and continuously develop their operations. In this context, it is also important to remember tangible benefits such as increased convenience and improved working comfort. Once such a system is implemented, the problem of searching for switches or dealing with poorly lit rooms disappears, as everything operates automatically.
