Gas sensors are devices that detect and measure the concentration of specific gases in the air. GMS20F-100 is a high-precision non-dispersive infrared sensor for carbon dioxide (CO2) detection, with excellent detection performance, reliable performance, fast sampling speed and long service life.

GMS20F-100 is suitable for air quality detection in various occasions such as greenhouses, warehouses, classrooms, rental units, residences, offices and other places. It can quickly detect the content and concentration of CO2 gases in the air accurately, and feed back the data in real time to ensure the safety and security of air indoors.

The working principle of GMS20F-100 is based on the non-dispersive infrared (NDIR) technology. NDIR tech works by measuring the differences in light absorptions in mid-infrared wavelength, around 4.26μm, which is in between the infrared spectra of CO2 absorbances and other gaseous components.

At the heart of GMS20F-100 lies an infrared LED and photodiode. The infrared LED emits infrared light at the same wavelength. The gas sample passes through the sensor chamber and the gas molecules absorb some of the light. This absorption is detected by the photodiode and the signal amplified through the circuit. The concentration of the gas molecules is determined by measuring the light intensity and calculating the absorbance.

Furthermore, GMS20F-100 has an advanced linearization technology that allows for linear and accurate readings. This helps increase the accuracy and reliability of the sensor. Additionally, the sensor is equipped with a memory chip that records data for long-term tracking and analysis of air quality changes.

In terms of calibration, the GMS20F-100 requires field calibration of sensors prior to use. This is to ensure that the readings from the sensor are accurate. The calibration procedure is simple, and the calibration process only takes a few minutes. And only after the calibration is finished, the sensor can provide detailed information on the gas concentration in various environments accurately.

In short, the GMS20F-100 is an effective gas sensor for sensing carbon dioxide concentration with excellent accuracy, reliability and simplicity. With its fast response time and high precision, the GMS20F-100 is the perfect choice for accurate detection of CO2 levels in the air.
