pir sensor output voltage!!!
hi , everyone
i want ask about the question about PIR sensor..
when the pir sensor is sense movement, the output voltage is 3.3V
the output voltage will drops to zero when there is no movement after 3 seconds..
although the jumper position setting already is connect at H position..
anyone can solve this problem to delay the time before when it drops to zero?

i'm using this PIR for automatic lighting inside a classroom..
but if im using the timer to set the time period, after the time period when there is still no movement in classroom, the light will automatic off.
