GP2Y10x Dust Sensor Sharp Microelectronics GP2Y10x Dust Sensor features a built-in infrared emitting diode, photodiode, and signal processing circuit. The dust sensor detects low density, small dust, and a single shot of house dust. The GP2Y10x sensor utilizes an air purifier's natural diffusion of dust and airflow. This GP2Y1026AU0F high-concentration sensor comes with a built-in microcomputer and features digital signal (UART) temperature correction averaging output. The sensor operates in a -10°C to +65°C temperature range and is available in a package with 46mm x 34mm x 17.6mm dimensions.
