2. White color(non- transparent ). The most popular color used in the smart home products, alarm system, white household appliances, etc.
3. Design color. Most of the customer choose black since black color against the bright light.
The fresnel lens is a optical element, one side is smooth, another side is by a ring a part of concentric garden composition. Fresnel lens arrays designed for Passive Infrared Sensor. The optical surface increases lens sensitivity for PIR sensor application. All the PIR sensor must work with the Fresnel Lens.
The Advantages of Products
1. Easy to install
2. High quanlity
3. Factory price
1. What is the payment term?
TT 100% in advance.
2. What is the package.
The appilcation of Fresnel Lens. When people goes in to the detect rang, Fresnel lens fouse the infrared on the PIR sensor, then the PIR sensor will change the optical signal to electrical signal in order to realize the PCB works.View More
