Now available from PMD Way is this neat Sharp optical dust sensor. This has an internal infrared diode and a phototransistor diagonally arranged - the diode projects light and the phototransistor detects the dark spots caused by the fine particles passing through. In addition to this feature, depending on the pulse pattern outputted you can check whether or not is smoke or dust. This is the sensor you will need if you want to measure air particles, build an air purifier system, or detect certain particles. Includes a special cable to connect with other applications. Specifications: Supply voltage: 5~7V DC Operating temperature: -10~65 degres Celsius Current: 20mA max, 11mA typical Output of the sensor is an analog voltage proportional to the measured dust density, with a sensitivity of 0.5V/0.1mg/m3.
