More info

Air quality sensor SDS-011 use laser scattering technique. His benefits are high resolution, fast response and easy integration.

               

Technical data:

                • Output: PM2.5, PM10

                • Measuring Range: 0.0-999.9μg/m3

                • Input Voltage:5V

                • Maximum Current: 100mA

                • Sleep Current:2mA

                • Response Time1 second

                • Serial Data Output Frequency: 1 time/second

                • Particle Diameter Resolution:≤0.3μm

                • Relative Error:10%

                • Temperature Range:-20~50°C

                • Physical Size: 71mm*70mm*23mm

        • Data interface - UART TTL

        • Work time- over 6 months depends on air quality For longer working time sensor should be cleaned gently by compressed air  (specially fan).

Device can be connected to Lan Controller V3 for remote air quality monitoring. Exemplary measurement making by this sensor and Lan Controller is presented on site: www.powietrze.radom.pl
