The six-in-one air quality sensor R66 is designed by Sysolution technology Company for the smart city and intelligent environmental monitoring fields, mainly to measuring the atmosphere PM2.5, PM10, ambient temperature, relative humidity, illumination and noise parameters. The product has a beautiful appearance and high degree of integration.
R66 can be applied to urban grid-based environmental monitoring and controlling, intelligent street lights, scenic environmental monitoring, factories or mines, construction sites (site dust monitoring), urban roads, highways, public places and other places involved in air quality monitoring.
Parameter Description
Noise: High-precision electric pickups are selected to measure environmental noise in A-weighting mode. With small size, high precision, high sensitivity and other characteristics.
PM2.5, PM10: Digital universal particle concentration sensor based on laser scattering principle, which can continuously collect and calculate the number of suspended particles of different particle sizes in the air per unit volume, i.e. particle concentration distribution, and then convert into mass concentration, and output in the form of universal digital interface.
Illumination/radiation/photosynthesis: choose different specifications of optical components with special filters to measure light, total radiation, photosynthesis, UV and other data, integrated design without moving parts.
