NOTES: 1.
The C8, D1, Z1, R7 components generate the DC Supply Voltage for the LS6506R.
2.
The R2, C2, R3, C3, R4, C4, R5, C5, R6, C6 components and the two on-chip Differential Amplifiers
set a nominal gain of 2,000 with bandpass filtering of 0.5Hz to 10Hz.
3.
R5 may be replaced with a potentiometer in order to adjust the Sensitivity.
4.
The value of R6 may have to be adjusted if the selected PIR Sensor causes the input static voltage
at Pin 15 to be out of the Input Dynamic Range.
5.
LR1 output closes contacts of Relay LR. LR2 output opens contacts of Relay LR.
6. Total Earth Ground current is typically 450uA RMS.
