Sharp GP2Y1010AU0F Optical Dust Sensor - PM2.5/PM10 Detection

The Sharp GP2Y1010AU0F optical dust sensor is an essential component for monitoring air quality. Its advanced infrared diode technology reliably detects airborne particulates, making it suitable for various air purification systems. Unlike many sensors, it adeptly differentiates between smoke and dust particles, thanks to its unique pulse pattern analysis.

This sensor excels with its dual-purpose functionality, distinguishing between fine smoke particles ranging from 0.3-1µm and larger dust particulates measuring 1-10µm. Its capability to differentiate these particulates ensures it's effective in various environments, from urban settings plagued with smog to interiors requiring pristine air quality.

The device outputs a linear analog signal, generating 0.5V for each 0.1mg/m³ change in particle density within a 0-3.5V range. This feature allows for precise PM2.5 and PM10 measurements, making it compatible with any microcontroller ADCs. Such precision in measurement is crucial for detailed air quality analyses and adjustments in real-time.

Enclosed in a robust 59×45×22mm housing, the sensor is designed for durability. Its construction allows it to function efficiently across temperatures from -10°C to 65°C, maintaining reliable performance even in high-humidity environments. This makes it a versatile choice for both indoor and outdoor applications.

With a low-power operation of just 11mA, reaching a maximum of 20mA during continuous monitoring, it suits battery-powered air quality stations perfectly. This efficient energy consumption ensures prolonged operation, reducing the need for frequent maintenance or battery replacements.
