Nova SDS011 Fine Dust Sensor

The Nova Fitness PM2.5 SDS011 fine dust sensor operates on the principle of scattered light and can measure particle concentration between 0.3μm and 10μm in the air. The sensor has a serial output for communication. Also included is a USB-Serial adapter with which you can read the sensor directly from your PC. The lifespan in continuous operation is only one year, so only switch on the sensor for measurement and then go back to standby. This way, you can achieve a lifespan of about 8 years.

Why not build your own fine dust sensor and deliver your measurement data to Luftdaten.info, thus supporting this project and contributing to a more comprehensive fine dust pollution map here in Switzerland. No programming skills are needed, and there is a very detailed construction guide at Luftdaten.info.
