Iranian Firm Builds Cost-Effective Smart Device for Dust Measurement
“This device measures dust based on the microgram per cubic meter standard. It has active laser sensors and also a battery and solar panel,” Mohammad Bayati Poudeh, a faculty member of Islamic Azad University, told ANA.
“The prototype of this device was used on the shores of Lake Urmia, but it is now being used in three locations in the country,” he added.
Bayati Poudeh explained that after detecting the level of pollution and its location, immediate action is taken to control the pollution, for instance by planting the black cumin plant, noting that the Iranian model of the device is provided to users with more features, including a battery and solar panel and allows sending information to the center.
In a relevant development in March 2024, Iranian researchers at the same company had also managed to produce a dust particle mass analyzing device which measures the risk of cancerous hazards in air by polluting particles.
“The device includes an inverse Frisbee trap. The Frisbee dust meter is a non-directional passive device that includes two dry and wet handles, and the Frisbee-shaped fall sediment collection container is made of anodized aluminum which is put 8.1 meters above the ground level and has a drain pipe which leads down from the pole to the rainwater collection bottle on the ground,” Bayati Poudeh told ANA at the time.
“This device also has a protector made of fine fishing wire in the form of a ring (with a thickness of 1 mm), which is placed 5 cm above the dust collector container on the bases (made of stainless steel or aluminum),” he added.
Bayati Poudeh explained that after a month, the Frisbee is removed from the bottom disk, which is still in place, and sent to the laboratory for measurement, and the insoluble matter is weighed, dried and assessed.
