PT8A2612 PIR Sensor Light Switch Controller

The PT8A2612 is a CMOS LSI chip based on 260 base designed for use in automatic PIR lamp control. It can operate with a 2-wire configuration for triac applications with dimmer function or 3-wire configuration for RELAY application. Its PIR sensor detects infrared power variations induced by the motion of a human body and transforms it to a voltage variation..

• General Description The PT8A2612 is a CMOS LSI chip based on 260 base designed for use in automatic PIR lamp control. It can operate with a 2-wire configuration for triac applications with dimmer function or 3-wire configuration for RELAY application. Its PIR sensor detects infrared power variations induced by the motion of a human body and transforms it to a voltage variation. If the PIR output voltage variation conforms to the criteria (refer to the functional description), the lamp can softly turn on as the below order, 25% lighteness, 50%, 75% 100% as well as turn off as reverse order w.
