Study Notes
Functions of Timers
- Timers automate the on/off operation of lighting and electrical devices based on pre-set timings, promoting energy conservation.
- Two types of timers are available: mechanical and electronic, with electronic timers being more prevalent due to being economical and accurate.
- Smart devices with built-in electronic timers are widely used in modern building automation systems.
- In shopping malls, timers manage complex lighting schedules, activating internal lights during operational hours and turning them off after closing.
- Household appliances like washing machines and microwaves utilize timers to control their operating cycles effectively.
Functions of Sensors
- Sensors function as input devices in building automation systems, providing feedback for necessary responses.
- Common examples include lift door sensors, temperature sensors for cooling systems, and smoke detectors triggering fire alarms.
- Sensors enhance convenience and safety in daily life, automatically managing various tasks based on environmental feedback.
Motion Sensors
- Motion sensors, or motion detectors, identify moving objects, especially people, within a specific detection range (5 to 30 meters).
- They can automatically control lighting systems, turning lights on when motion is detected and off when no motion is present.
- Passive infrared (PIR) sensors are commonly used for their sensitivity to the motions emitted by objects.
Light Sensors
- Light sensors, also known as photo sensors, convert light energy (visible and infrared) into electrical signals.
- They play a vital role in adjusting lighting levels and enhancing energy efficiency by responding to ambient light changes.
Temperature Sensors
- Temperature sensors detect and measure changes in temperature, crucial in environments needing temperature regulation.
- They are utilized in fire alarms to indicate sudden temperature rises and in HVAC systems to maintain desired climatic conditions while optimizing energy use.
Window Sensors
- Window sensors function in pairs: one adheres to the window and the other to the frame, detecting when the window is opened.
- They can be integrated into home security systems, sending alerts when separation occurs, thus enhancing property security.
Energy Conservation with Timers and Sensors
- Effective energy saving involves deactivating lighting and electrical devices when not in use.
- Examples include automatically opening doors without physical contact in hospitals and adjusting escalators to sleep mode during inactivity.
- Motion-detecting sensors can trigger alerts in burglar alarm systems and activate security cameras.
- Use of light sensors enables automatic adjustments of indoor light levels based on natural light availability.
- Advanced systems combine timers and sensors to manage lighting in different building areas, ensuring optimally scheduled operations.
