Real time online monitoring of environmental pollution is one of the ways to control and prevent the dangers of natural disasters. Water pollution in the environment directly affects human health and living organisms is also very important that requires online monitoring and early warning capabilities. In this research, using the surface Plasmon resonance effects of gold nanoparticles and based on optical-fluidic spectroscopy, the amount of water pollution is measured and the data are sorted, analyzed and sent on the Internet of Things. Nanoparticles made by combining chemical and physical methods used to interact with water contaminants and make a change in the optical response of the oscillation of metal electrons, which identifies the amount and type of contamination.
