Smart dust refers to an ultra-miniature sensor with computer functions. It can detect many environmental parameters around it, collect large amounts of data, perform appropriate calculation processing, and then use two-way wireless communication devices to transmit this information between dust devices separated by 1,000 feet. Smart dust has a wide range of applications. In addition to being primarily used in the military field, it can also be used in health monitoring, environmental monitoring, medical care, and many other aspects.

The principle is that smart dust is an ultra-miniature sensor with computer functions, composed of a microprocessor, a two-way radio receiver, and software that enables them to form a wireless network. By scattering some dust in a field, they can locate each other, collect data, and transmit information to the base station. If one dust device malfunctions, others will repair it.

Smart dust is a miniature sensor that transmits information wirelessly, with a volume positioned at 5mm3 and below.

Luftmy’s dust sensor is a dust concentration detection device and cleanliness detector that uses infrared counter-radiation and Lambert-Beer law. It can accurately detect particle quantity and concentration data in the ventilation ducts of equipment such as vacuum cleaner handles or extension poles, sweeping robots, range hoods, and particle testing instruments.

When the dust sensor is placed in vacuum cleaning equipment and used on scenes such as floors, carpets, and bed sheets, the dust sensor device intuitively presents the sensor output data and LED color display to the user.
