BISS0001 is a PIR (passive infra-red) controller, using analog mixing digital design technique and manufactures by CMOS process. With special noise immunity technique, BISS0001 is the most stable PIR controller you can find on the market. More than this, there are few components needed in its application circuit which can reduce material cost and increase competitive.
