Is PIR a common device used for detecting motion indoors on a security alarm system?
Yes it is, a PIR stands for Passive InfraRed, which detects heat signatures. For a higher level of security, I would recommend dual band motion detectors with PIR and Microwave Detection capability.

How does a traffic light timer work?
It is acctually a sensor.
How well does a day and night air conditioning system work?

How does proximity sensor work?
Without physical contact detecting the presence of objects is the purpose of proximity sensors. They work based on inductive, magnetic, photoelectric and capacitive properties of objects.
What does pir in lighting stand for?
PIR = passive infared They detect motion and then activate a switch to turn things on and off
A very simple explanation of working principle of PIR sensor by a very simple example?
The PIR sensors use the detectors or pyroelectric sensors to work. Example include the automatic door openers.
Where can one obtain a Pir sensor?
A PIR Sensor can be purchased at any specialty electronics store. It is a sensor primarily used for sensing changes in infrared energy. It is a highly specialized motion detector.
Why LDR used in PIR sensor?
industrial automaton
Can a PIR Motion sensor be used to detect humans or human movement?
A PIR Motion sensor detects the minute changes in heat and infrared radiation rather than movement.
What is Common device used for detecting motion indoors?
A Passive InfraRed Sensor (PIR)
How do you install a pir sensor?
Normally a PIR sensor has three cables. Brown: + Blue: - Red: Sensor control Connect the brown and the blue to your power in. All lamps must be connected to blue and red. When the sensor detects movement it "transfers" the ingoing power from the brown wire to the red wire meaning that the lamps for a given period has both + and - = the light up.
Will a pir security light work in a closed porch?
Yes but the dawn to dusk feature normally built in may not operate correctly due to low light levels but the PIR function will work perfectly well.
