ABSTRACT
An Embedded system is a controller programmed and controlled by a
Real-Time Operating System (RTOS) with a dedicated function
within a larger mechanical or electrical system, often with Real-Time
computing constraints. Embedded systems control many devices in
common use today. The project aims to design an air, water, and
noise pollution monitoring and controlling using internet of things.
The level of pollution has increased with times by lot of factors like
the increase in population, increased vehicle use, industrialization
and urbanization which results in harmful effects on human
wellbeing by directly affecting health of population exposed to it. In
order to monitor quality of air, water quality and sound level of the
environment over IoT based new framework is proposed which is
based on data acquisition, transmission and controlling. The proposed
bridgeless converter precedes a flyback converter to manage the
charging of 48V/100Ah battery throughout the constant current (CC)/
constant voltage (CV) profile as well as built-in PFC capability at the
mains side is inherited. An 850W prototype is designed and
developed tosupport the enhanced performance of the battery charger
by reconstructing the line current waveform and significantly
reducing the input harmonics distortion to the recommended IEC
61000-3-2 standard.
