SDS011 Laser PM2.5 Air Quality Sensor

Description : SDS011 is a professional laser dust sensor. Fan mounted on sensor automatically sucks air. Sensor uses laser light scattering principle to measure value of dust particles suspended in the air. Sensor provides high precision and reliable readings of PM2.5 and PM10 values. Any change in environment can be observed almost instantaneously - short respond time below 10 seconds. Sensor in standard mode reports reading with 1 second interval. They are two ways to communicate with SDS011 sensor: digital out (UART) PWM signal (one for PM2.5 and one for PM10) Set includes: Nova Fitness SDS011 sensor cable USB-UART converter Specification: Measured values: PM2.5, PM10 Range: 0 - 999.9 μg /m³ Supply voltage: 5V (4.7 - 5.3V) Power consumption (work): 70mA±10mA Power consumption (sleep mode laser & fan): < 4mA Storage temperature: -20 to +60C Work temperature: -10 to +50C Humidity (storage): Max. 90% Humidity (work): Max. 70% (condensation of water vapor falsify readings) Accuracy: 70% for 0.3μm 98% for 0.5μm Size: 71x70x23 mm Pinout: Pin 1 - not connected Pin 2 - PM2.5: 0-999μg/m³; PWM output Pin 3 - 5V Pin 4 - PM10: 0-999 μg/m³; PWM output Pin 5 - GND Pin 6 - RX UART (TTL) 3.3V Pin 7 - TX UART (TTL) 3.3V - Librairie Arduin - Fiche technique SDS011 (828 ko) - Manuel d'utilisation (628 ko)
