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

The sensor detects approx. 1㎛ particle such as house dust, pollen, germs, dust mites and cigarette smoke and measures the concentration of floating particles in a room space up to maximum 30㎥.

This sensor is an ideal product for automatic room air monitoring system such as an air purifier.

The signal is converted to PWM output by internal circuit and MCU program.
Also, the sensor’s filter circuit and MCU program can remove a noise in order to operate more stably when a noise is in-flowed in the signal.
MDSM has advantages of both stable detecting ability and high manufacturing efficiency.
