INFRARED SENSORS FOR UNINTERRUPTED PROTECTION FROM TRESPASSER

Posted: August 20th, 2014 | Author: admin | Filed under: Infrared Sensor | Tags: | No Comments »

An infrared sensor is an electronic instrument that is used to sense certain characteristics of its surroundings by either emitting and/or detecting infrared radiation. It is also capable of measuring heat of an object and detecting motion. Infrared waves are not visible to the human eye.

In the electromagnetic spectrum, infrared radiation is the region having wavelengths longer than visible light wavelengths, but shorter than microwaves. The infrared region is approximately demarcated from 0.75 to 1000µm. The wavelength region from 0.75 to 3µm is termed as near infrared, the region from 3 to 6µm is termed mid-infrared, and the region higher than 6µm is termed as far infrared.

Infrared technology is found in many of our everyday products. For example, TV has an IR detector for interpreting the signal from the remote control. Key benefits of infrared sensors include low power requirements, simple circuitry, and their portable feature.

Infrared sensors have many applications on day to day life. Such as tracking and art history, climatology, communications, alcohol testing, heating, gas detectors/gas leak detection, flame detection, petroleum exploration and rail safety.

The LED type of infrared sensor is used to detect the target and illuminate it. The reflected energy is focused onto a detector. Photoelectric cells, photo-diode or photo-transistors are used as detectors in this type of arrangement. The measured data is then processed using various signal processing instruments to extract the required information.

ALEKO® Photo Cell Infrared Sensor designed specifically for outdoor intrusion detection applications. Dynamic IR innovation might be utilized for identification of undesirable components utilizing a two-section sensor. It comprises of a transmitter unit that transmits undetectable dynamic infrared bars. The recipient unit gets and examines the shafts and catches gatecrashers who pass between the two segments.

Passive infrared technology uses heat radiation to detect intruder movement. The temperature differentiation is effectively located by the sensors to judge an irregular movement.  The reliability of the operation is assured by the rugged construction of the system, the integrated heaters and the self-adapting technology. Despite the changing environmental condition or temperature extremes, the capacity of detecting intruders remains steadfastly high.

If you are looking for long range and high performance outdoor infrared sensor, then there are lots of models available. They can easily detect walking, running and even crawling intruders. But the best model is the source of active IR emissions. It also has a receiver unit which receives the signal, analyzes them and detects any intruder movement passing between the two units.

It is wise to research on the different type of sensors available in the market before buying for your need. If you can’t decide, then we at Wholesale gate openers are experts in garage door sensors. Contact us for advice on the right kind of sensors.
