Gas sensors are used in a variety of applications to detect the presence of hazardous gases, such as carbon monoxide (CO) and other toxic compounds, in the atmosphere. One type of gas sensor, known as an infrared (IR)11BR, has become increasingly popular due to its simple construction and robust performance. In this article, we will discuss the application field and working principle of the IR11BR gas sensor.

The IR11BR gas sensor is designed primarily for the detection of CO in the air. It consists of a single sensor head with an infrared (IR) source and a detector unit which are connected to a signal conditioning board. The IR source is composed of three LEDs; one for near infrared (NIR) light, one for mid infrared (MIR) light, and one for far infrared (FIR) light. The detector unit is composed of three detectors; one for NIR light, one for MIR light, and one for FIR light. The signal conditioning board is responsible for the signal amplification, filtering, and analog-to-digital conversion of the signals from the detector unit.

The working principle of the IR11BR gas sensor is based on the change in the intensity of the radiation from the LED source when subjected to the presence of CO. When exposed to CO, some of the infrared (IR) radiation emitted by the LED source will be absorbed by the CO molecules, resulting in a decrease in the intensity of the radiation that is detected by the detector. The signal conditioning board is then used to amplify the signal, filter out any noise and convert the signal into a digital format which can be read by the system.

The main application field for the IR11BR gas sensor is in the field of environmental monitoring. It is commonly used in air monitoring systems to detect CO and other toxic compounds in the atmosphere. It is also used in industrial processes, such as combustion engines, to detect the presence of CO in the exhaust gases to prevent excess emissions. The sensor is also used in automotive applications to detect the presence of hydrocarbons in gasoline and diesel fuel.

The IR11BR gas sensor is a reliable and robust sensor for detecting CO in the atmosphere. Its simple construction and robust performance make it ideal for use in a variety of applications. It is capable of detecting CO at a wide range of concentrations, making it suitable for use in environmental monitoring and other industrial applications.
