How is IR used in intruder alarm?
Whenever IR beam between the transmitter and the receiver is interrupted, the alarm circuit is triggered and the buzzer sounds continuously. It can be reset only by pressing the reset button.
What is IR security alarm?
IR based security alarm circuit can detect any movement and trigger the alarm. This circuit is very useful in homes, banks, shops, restricted areas where an alert alarm is needed on any movement.
How do I make my super sensitive intruder alarm?
Super Sensitive Intruder Alarm Circuit Principle:
- Obstacle Present → IR Receiver Receives IR Rays → Op-amp Output High → 555 RST Pin High → Speaker Produces the Sound.
- No Obstacle → IR Receiver does not Receive the Rays → Op-amp Output Low → RST Pin Low → No Sound.
What is super sensitive intruder alarm?
In the event that there is a hindrance in front of the IR sensor, it delivers an intrude signal. This interruption signal is given to the speaker to alert the individual.
What are the applications of IR sensor?
Other key application areas that use infrared sensors include:
- Climatology.
- Meteorology.
- Photobiomodulation.
- Flame Monitors.
- Gas detectors.
- Water analysis.
- Moisture Analyzers.
- Anesthesiology testing.
What is infrared CCTV?
Infrared CCTV cameras use infrared LED lighting positioned around the outside of the camera lens in order to capture information. Even in areas where there is absolutely no light. Although infrared CCTV cameras are often referred to as night vision cameras, don’t confuse them with ‘day/night’ cameras.

Where is infrared sensor used?
Application of Infrared Sensors Infrared sensors from InfraTec are used in gas warning devices, gas analysers, medical gas measurement technology, flame detectors and in contactless precision temperature measurement. These devices use the intensity measurement of infrared radiation in defined spectral ranges.
What is the disadvantage of IR sensor?
Following are the disadvantages of Infrared sensor: ➨Infrared frequencies are affected by hard objects (e.g. walls, doors) , smoke, dust, fog, sunlight etc. ➨Infrared waves at high power can damage eyes. ➨In monitor & control application, it can control only one device at one time.
How to make an intruder alarm with IR sensors?
Infrared (IR) sensors are normally used to measure distances, but they can also be used to detect objects. By connecting a couple of IR sensors to an Arduino, you can make an intruder alarm. Infrared (IR) sensors are normally used to measure distances, but they can also be used to detect objects.
What is Irir based security alarm circuit?
IR based security alarm circuit can detect any movement and trigger the alarm. This circuit is very useful in homes, banks, shops, restricted areas where an alert alarm is needed on any movement.
What is an IR based security system?
IR Based Security Alarm. This circuit is very useful in homes, banks, shops, restricted areas where an alert alarm is needed on any movement. This circuit is based on IR sensor where an IR beam is continuously falling on a photodiode, and whenever this Infrared beam breaks, by any kind of movement, alarm is triggered.
What is the working principle of IR alarm system?
This circuit is based on IR sensor where an IR beam is continuously falling on a photodiode, and whenever this Infrared beam breaks, by any kind of movement, alarm is triggered. IR sensor consist an IR LED and photodiode, in which IR LED emits IR radiation and photodiode detects the radiation.
