Product Summary

PSMU Series is PM2.5 dedicated sensor providing uniform performance and excellent accuracy in weight concentration value by detecting over 0.3㎛ sized ultra-fine particle through SAMYOUNG S&C’s proprietary optical structure with IrED.

KEY NOTE

PSMU Series, in which SAMYOUNG S&C’s 20years knowledge and technology are concentrated, is a PM2.5 dedicated sensor with a radical improvement for detection capability at ultra-fine particle range 0.3㎛~1.0㎛, which assures PM2.5 weight concentration values more accurate than conventional presumptive sensors.

PSMU Series which performs higher accuracy along with improved sensitivity than conventional sensors provides reliable information to users enabling more accurate and sophisticated control in the applications such as air purifiers, air conditioners and air quality measuring devices.

SAMYOUNG S&C has developed a system to reliably mass-produce PSMU Series of uniform performance by a mass calibration technology which also contributes to efficient production. Moreover, the patented aerodynamic optical structure maximizes the performance of the sensor and improved the quality of the product. In addition, it provides real-time PM2.5 weight concentration values in UART output for user convenience.

Product Summary

PSMG 시리즈는 삼영에스앤씨의 독자적인 광학구조를 통해 IrED를 발광소자로 0.3㎛ 크기의 초미세먼지까지 감지하여, 측정된 먼지 를 MCU를 통해 LPO 값으로 변환, PWM으로 출력하는 PM2.5 전용 센서입니다.

Keynote

PSMG 시리즈는 삼영에스앤씨의 20년 간의 노하우와 기술이 집약된 먼지센서로 초미세먼지 영역인 1㎛ 이하 0.3㎛ 이상의 먼지 감지 능력을 획기적으로 향상시켜 기존의 센서보다 더 세분화된 PM2.5 레벨을 구분할 수 있습니다.

기존 먼지센서에 비해 높은 정확도와 감도 특성은 사용자에게 신뢰도 있는 정보를 제공하며, 공기청정기, 에어컨 및 공기질 측정 디바이스에 적용함에 있어 보다 정확하고 정교하게 컨트롤 할 수 있게 되었습니다.

삼영에스앤씨는 Mass Calibration 시스템 개발을 통해 생산의 효율성과 균일성을 향상시켰고, 특허 출원된 광학 구조를 통해 센서의 품질과 성능을 최대화하였다. 또한, 사용자의 편의성을 고려하여 기존 제품과 1:1 호환이 가능하도록 설계 하였습니다.
