• All human body has stable temperature, 
generally 37'C. Therefore they can send out 
infrared rays with specific wave length about 1 
0 micrometers.
• The PR sensors are tuned to detect these IR wave 
length which only emanates when a human being 
arrives in their proximity. i.e. it senses the motion 
of human body by the change in surrounding 
ambient temperature.
• The term "PYROELECTRICITY" means heat that 
generates electricity (here, an electric signal of 
small amplitude). Since these sensors do not 
have an infrared source of their own, they are 
also termed as "Passive"
