Function
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.
