Based on the light scattering method, it detects airborne particles continuously, then outputs the detection result in UART digital output based on mass concentration (μg/m3).


Air Purifier; Air Quality Monitor; Air Conditioner; Ventilator.



Redesigning sensor structure achives the smallest 

sensor ever.

Digital output by UART communication offers you 

designing software easily.

New optical design and MCU provide better accuracy 

and fine particle sensing.

Using custom-made key optical parts achieves 

long operating life time with high reliability.
