  • Whatthe Problem with Low-cost Air Quality Sensors?

    At best, low-cost air quality sensors can provide air quality monitoring of specific pollutants. However, without the ability to conduct in-depth air quality data analysis and advanced QA, the accuracy of the low-cost air quality sensors pollutant readings cannot be relied upon completely. There is also no guarantee that low-cost air quality sensors can decipher between the different types of key air pollutants, which is just as critical as having the ability to provide the accurate levels

  • Sensor Calibration- Working Principle and ItApplications

    Working PrincipleApplications of Sensor CalibrationUse of Sensor CalibrationSensor calibration helps in improving the performance and accuracy of the sensors. There are two well-known processes in which sensor calibration is done by industries. In the first method companies add an In-house calibration process to their manufacturing unit to perform individual calibration of the sensors. Here the company also adds necessary hardware to their design for sensor output correction. By this process, the sensor calibration can be changed to match the application-specific requirements. But this process increases the time to market. The alternative of this In-house calibration process, several manufacturing companies provides sensor packages with a high-quality automotive-grade MEMS sensoralong with complete system-level calibration. In this process, the companies include an onboard digital circuitry and software to help designers to improve the functionality and performance of the sensors.
