WT8072
PIR CONTROLLER
To set up the timing of how long Triac or relay is active.
During the period, if the system receives the PIR signal, then it restarts
counting the timing again.
The range for R: 10K < R < 1M Ohm
C: 100uF< C < 0.1 uF (Reference Diagram 2)
Connected to a CDS for inhibiting relay or TRIAC being triggered.
If TRIAC or relay has already being triggered by PIR signal and turned into
active mode, then CDS can not inhibit PIR again.
To trigger TRIAC, active low
Sink current: 15 mA max.
To drive relay, active high
Sink current: 10 mA max.
Source current: 10 mA max.
Detect zero cross of AC line under remote mode function.
Operation voltage: 5V, stand by current: 1mA
2nd stage OP amp negative input
2nd stage OP amp positive input
2nd stage OP amp output
