PIR Sensor Tester

Application

The required variables:
•Integration Time – period for averaging of the individual pulses of the occurrence;
•Alarm duration – the period, that is indicating the start of the occurrence;
•Pulse width – the duration of each individual pulses;
•Background level – the differential zero;
•Upper and Lower limits – the threshold.

The singularity of Rigado Snap Connector schematic is the filter for purpose of pulse mode retranslation to the level threshold. So the necessary parameter for that structure is:
•Attenuation – the period for discharging of the capacitor (4,7uF is used);
•Averaging multiplier – the pulse amplitude is not changing during the event.
