1.Designed for passive infrared sensor applications 
2. Easy to cut; high compatibility , low cost and environment 
3.Can be used in applications including  security system, lighting controls and environmental controls 
4.Optimized for dual element pyroelectric devices 
5.White light immunity can  reduce false triggers 
6.UV resistant for outdoor applications 
7.Designed for uniform sensitivity to reduce electronic gain

The Fresnel lens has two functions as follows
1. The focusing action, soon hotly releases the infrared signal refraction (reflection) on PIR,
 2. Fresnel lens divides the search coverage into detection area  and non-detection area. PIR can generate pyroelectric infrared sinal when moving object enters the detection area making the change of temperature.
