PIR Control Infrared Ray Integrated Circuit

 

General Description
The CS9803 is a passive infra-red controller, using analog mixing digital design technique and manufactures by
CMOS process which can either driver TRIAC or RELAY depending on user’s choice.
With special noise immunity technique, CS9803 is the most stable passive infrared 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.
