how to integrate mini infrared security system with Arduino?

I have a question.....

Can i somehow integrate mini infrared security system PEM 7D

with Arduino ??

Grateful for answers

If only with the sensor?

Looks like you could take the speaker output from the IR detector and (MAYBE THRU SUITABLE ELECTRONICS) make it compatible with an Arduino input pin so you can detect beam breaks.

You will need to determine what type of signal comes out of the IR output as an Arduino UNO pin can only handle positive voltages between 0V and 5V.

Check item/pin 5 which goes to an external counter, see what signal you get there when the beam is broken.

thanx for your answers :smiley:

I should check this
