Objective
To construct and testing the PIR sensor circuit
Activity
The construction for the PIR sensor circuit is follow circuit below:
The construct and testing using PIR sensor. Without using PIR module. This circuit is using amplifier is to convert the PIR sensor output to suitable output in voltage. Using relay 12V to switch on to deliver output active high or active low to LED. Free willing diode that connected between relay is to prevent transistor receive continuous supply from relay. It may recycle back within the relay only.
