Winsen ZH03A is a laser dust sensor which can detect PM1.0, PM2.5 and PM10 particles. Its small size and low price should make it a great add-on to volatile organic compounds (VOCs) and carbon dioxide (CO₂) sensors from FIGARO Engineering and Amphenol Advanced Sensors.

The air pollution in biggest cities is a growing problem. Regarding to World Health Organization (WHO) constant living in high concentrations of PM2.5 may lead to shorten of average life length. Even short exposure contributes to risk of developing cardiovascular and respiratory diseases.

Winsen ZH03A is ideal for portable and stationary air quality monitors, air purifiers, ventilation systems and smart home equipment.
