This dust sensor, in the detection of very fine particles, such as cigarette smoke, is particularly effective and is commonly used in air purifier systems.
The sensor has very low current consumption (up to 20mA, 11mA typical), can carry up to 7VDC sensor. The output is an analog voltage proportional to the measured dust concentration, the sensitivity of 0.5V / 0.1mg / m3
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 aplications.
Sharp optical dust sensor 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.
Operating temperature: -10 to 65 Degree Celsius
Storage temperature: -20 to 80 Degree Celsius
Minimum particle detection value: 0.8 microns
Consumption 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.
Supply voltage: 5 to 7V
Life: 5 years
Size: 46mm * 30mm * 17.6mm
