When using lower-end or budget zoom lenses, the simple act of repeatedly zooming the lens in and out can “inhale” dust particles into the lens, which can then over time work their way into your camera. Once inside, they can settle on the mirror or sensor. Once you start changing lenses, the likelihood of dust finding its way to your sensor skyrockets. There are steps you can take to ...
2019-06-03· Networks of microelectromechanical sensors, or smart dust, are set to revolutionise the way the Internet of Things functions, transforming a whole range of sectors as a result.

2019-08-28· How Does the Dust Sensor Work? The dust sensor uses an optical sensing method to detect dust. A photosensor and an infrared light-emitting diode which is known as an IR LED are optically arranged in the dust sensor module. The photo-sensor (PT) detects the reflected IR LED rays which are bounced off of the dust particles in the air.

How do Sharp dust sensors work? Sharp dust sensors operate on the principle of light scattering. A photo-detector and LED emitter oppose each other at an angle within the rectangular package of the sensor which has a dust through hole on either side. Air containing dust particles flows into the sensor chamber and causes the light from the LED emitter to be scattered towards the photo-detector ...
This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in given time unit. LPO time is proportional to PM concentration. Global Dust Sensors key players include Omron Automation and Safety, Sharp, Shinyei Group, Amphenol ...
A1: The output signal from Dust Sensor needs to be scaled down to logic to work with Seeeduino Stalker (or any such board). The output from Dust Sensor is for Logic Low and greater than for Logic High. You could use a voltage divider to scale the output to be compatible with logic or use a TTL logic level translator.
