Iranian Knowledge-Based Firm Develops Solar-Based System for Measuring, Monitoring Air Pollutants
“This device works with solar energy and provides air monitoring information both online (internet system) and offline (city televisions) without any need to urban electricity,” said Sepehr Heydar Arabi, the managing director of the knowledge-based company.
“The device provides information about urban air pollution, including the concentration of PM2.5 and PM10 dust and polluting gases (O3, CO, NO2, SO2 and VOC) and meteorology (temperature, humidity, air pressure, sound, wind speed and direction),” he added.
Heydar Arabi underlined that the whole process of body design, electrical board, computer programming, online site and assembly has been carried out inside Iran by the country’s young researchers.
In another development, Iranian researchers had produced air purifiers which are recharged by simply putting them in the sunlight.
Earlier this year, Iranian researchers unveiled air purifiers that are capable of removing odors and environmental pollutants while they can be recharged without the need for electricity and only by solar power.
“These filters are produced based on two materials, one is able to absorb all kinds of air pollutants and the other material in this filter decomposes the pollutants,” Fatemeh Esmayeeli, a member of the research team that manufactured the device said.
Explaining how the air purifier works, she added, “The nano material used in this purifier has pores that when it is exposed to pollutants, the pollutants are placed on these pores and through this process, the pollutants are eliminated.”
Esmayeeli said that being anti-odor is one of the other characteristics of their device saying that this air purifier can remove bad smell if it is placed in closed places such as refrigerators and shoe racks.
Stressing that nano materials are used in the air purifier, the researcher continued, “These materials can detect pollutants and decompose them into water and carbon.”
