Application of photoacoustic sensor in environmental monitoring

　　Photoacoustic sensor is an environmental monitoring sensor based on photoacoustic effect. It uses the thermoelastic wave generated by the absorption of light energy to detect the concentration of pollutants in the environment.In the long run, solar energy applications The value will be higher and higher, and there will be a great leap in essence. https://www.codasensor.com/product-category/radiation-sensor

　　Photoacoustic sensor has the advantages of high sensitivity, good selectivity and no need for sample pretreatment. In the field of environmental monitoring, it has been widely used to detect pollutants such as sulfur dioxide and nitrogen oxides in the air. In addition, photoacoustic sensors can also be used to monitor heavy metal ions and organic pollutants in water.

　　However, the performance of photoacoustic sensor is affected by many factors, such as the stability of light source, the sensitivity of detector and environmental noise. Therefore, these factors need to be considered comprehensively in practical application to improve the detection accuracy and stability of the sensor.
