CS9803 PIR CONTROLLER CS9803 GENERAL DESCRIPTION CS9803 is a PIR (passive infra-red) controller, using analog mixing digital design technique and manufactures by CMOS process which can either drive TRIAC or RELAY depending on users' choice. With special noise immunity technique, CS9803 is the most stable PIR controller you can find on the market. More than this, there are few ponents needed in its application circuit which can reduce material cost and increase petitive.
