Abstract. This paper presents an important study of environmental Atmospheric analysis at industrial factories in Bangladesh. An Arduino based real time control system with gas and noise sensors has been developed to collect the data in various industries. The system then has been made operational at few cement factories to measure the noise (db) and dust (μg/m 3 ) and compared with international standard requirements to understand whether the factories are providing healthier environment. Result shows both the noise and air quality to be within the borderline except few cases in which the solution has been proposed to improve the factors.

In this paper, we proposed an IoT based solar-powered smart waste management system which is suitable for any kind city or town in both developed and developing countries that can ensure proper collection, transportation, and disposal of household and industrial waste with real-time remote monitoring. To maintain the green and clean environment around us, precise collection and disposal of garbage in a regular fashion are necessary. The primary goal of this research work is to provide a complete smart solution for waste collection and disposal hence ensuring a comfortable environment. The proposed system enables real-time remote monitoring of solar-powered several smart bins located in different points in the city which are connected to the control station through long-range (LoRa) communication device and also supervises the waste collector activities like collection and disposal time using Automated Vehicles Locating System (AVLS).
