Fresnel PIR lens has two functions: 1. It is the focusing effect, that is, the pyrolysis infrared signal is refracted (reflected) on the PIR. 2. The detection area is divided into a number of bright areas and dark areas, so that the moving object entering the detection area can generate a modified pyroelectric infrared signal on the PIR in the form of temperature change.
Security System: The Fresnel PIR Lens is frequently employed in security systems for motion detection and alarm triggering. When installed in a security camera or sensor, the lens is capable of precisely detecting movement within its field of vision. This application situation is perfect for home security systems, commercial buildings, and outdoor surveillance cameras. The Fresnel PIR Lens guarantees reliable motion detection, contributing to the enhancement of the overall security of the premises.
Energy Saving Lighting: The Fresnel PIR Lens is also utilized in energy-saving lighting systems. Through integrating the lens into lighting fixtures, the system can sense the presence of individuals in a room and automatically adjust the lighting levels accordingly. This application scenario is commonly witnessed in offices, warehouses, and public buildings where energy efficiency holds priority. The Fresnel PIR Lens helps to decrease energy consumption by ensuring that lights are only activated when necessary, resulting in cost savings and environmental advantages.
Automatic Doors: Another application case for the Fresnel PIR Lens lies in automatic door systems. By incorporating the lens into the door mechanism, the system can detect approaching individuals and automatically open the door. This is especially useful in high-traffic areas such as shopping malls, airports, and hospitals, where hands-free access is convenient and enhances accessibility. The Fresnel PIR Lens improves the functionality of automatic doors, offering a seamless and efficient entry experience for users.
HVAC Control: The Fresnel PIR Lens can also be integrated into HVAC (heating, ventilation, and air conditioning) systems for efficient temperature control. By detecting occupancy in a room, the lens can signal the HVAC system to adjust the temperature settings accordingly. This application scenario is beneficial in commercial buildings, hotels, and residential properties where maintaining a comfortable indoor environment is crucial. The Fresnel PIR Lens helps to optimize energy usage and enhance occupant comfort by providing precise occupancy-based temperature control.
Smart Home Automation: The Fresnel PIR Lens is a crucial component in smart home automation systems. By connecting the lens to a smart home hub or controller, users can establish customized automation routines based on motion detection. This enables hands-free operation of various devices and appliances in the home, such as turning on lights, adjusting thermostats, or activating security cameras. The Fresnel PIR Lens allows homeowners to increase convenience, security, and energy efficiency in their living spaces through intelligent automation solutions.
