Abstract: In this paper we propose a design for a home surveillance system with an enhancement circuit for the pyroelectric infrared sensor (PIR sensor) which has been included to improve the sensing ...

Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

Abstract: The work gives a report about the design of an energy saving system using a Passive Infrared Radio sensor to switch `off' fan and light circuits in the classroom in the absence of students.
