GENERAL DESCRIPTION
The WT8076 is a PIR controller IC which integrates amplifier, window detector and light control
functions. The light can be controlled by a Relay or Triac with adjustable delay time. A CDS interface is
provided to sense day time and night time. A walk-test fuction helps user while setting up the light set.
The line remote control function can switch the light set between auto mode and always-on mode.
FEATURES
Adjustable detection range
Adjustable delay time
CDS interface to differentiate night time and day time
Walk-test function
Line remote control to switch auto mode and always on mode
Relay or Triac output
High noise immunity
Low power consumption ( operating 500uA, standby 130uA, Typ. )
