Product Overview

Wireless Real-time Dust Monitoring System
for Construction Site, Schools & National Parks

(Model No.: RK300-02DBBD)

Product Features

RK300-02 Dust Sensor using laser scattering pinciple, detecting the existence of dust particle concentration in the air, the minimum can be 1.0um particles, has a good consistency and stability. According to different usage environment. There are indoor type and outdoor type to select. The outdoor come with solar radiation shield housing and can be powered by solar panel and rechargeable battery.

Real-time monitoring parameters: fine particulate matter (PM2.5), inhalable particulate matter (PM10). We provide RS485(Modbus) communication interfaces to rEye IoT Adaptor with NB-IoT islandwide connection, monitor by remoteEye IoT cloud platfrom.
