Switching automation is a popular solution for reducing energy consumption and increasing convenience. This technology involves using motion sensors, occupancy sensors, or light sensors to detect activity or changes in the environment and automatically turn on or off lights in response.
Switching automation is an effective way to reduce energy consumption and lower electricity bills, as lights are only used when they are needed. It also provides convenience for occupants, as they don't need to manually turn lights on and off. Switching automation involves using PIR and HF technology.
PIR Technology
PIR (Passive Infrared) technology is a common method used in many buildings. PIR sensors detect changes in infrared radiation within their range of view, which is emitted by moving objects that radiate heat, such as humans or animals.
When a PIR sensor detects a change in infrared radiation, it triggers an electronic circuit that controls the lighting system. This circuit can be programmed to turn on the lights when motion is detected and turn them off after a preset time when no motion is detected.
HF Technology
HF (High Frequency) technology is another method commonly used. HF sensors emit high-frequency electromagnetic waves that bounce off objects in a room and reflect back to the sensor. By measuring the time taken for the wave to reflect back, the HF sensor can detect the presence of people in the room.
When a person enters the room, the HF sensor detects their presence and triggers an electronic circuit that controls the lighting system. The circuit can be programmed to turn on the lights when motion is detected and turn them off after a preset time when no motion is detected.
One of the benefits of HF technology is that it can detect small movements, such as typing on a keyboard or turning a page, which can be useful in environments where people may be stationary for long periods. HF sensors can also be used to control the brightness of lights in response to the amount of natural light in a room.
