i had search some post in there, but the circuit is too complicate
i just want to increase pir's change ,so that i can use adc to make a digital output.
how can i do it?

Need to know part number and data sheet location of the PIR. Need the ADC's input voltage range. Also need to know what power supply voltages are available?

part number? i can't find data sheet of that pir, i can only see the word (KDS 6K)
ADC i think i would like to use 5V , that will be better if can use battery(AA) ,three to four,
