Description
SDS011 Nova Particle Sensor
Download SDS011 Datasheet
The SDS011 Particle Sensor is based on the Laser Scattering principle through which it detects the particle concentration in the surrounding air. The SDS011 Particle Sensor detects the scattered light and translates it into digital signals. The digital signals go through the amplification process and then the sensor produces the readings.Â
SDS011 uses the Laser Diode for real-time data. The service life of this high-quality diode is up to 8,000 hours. You can configure the sensor for Real-Time-Data (continuously). But if you do not need Live Tracking, for instance, 1-time per second, you can configure the sensor as you like, for example, one-time in 30 seconds or even once in 5 minutes.Â
