IOT offers systems that combine more than one disparate additive towards their synergistic use. Most of the world's population today lives in cities. By 2030, the population of the cities around the arena is predicted to grow from three.Three billion to five billion people. Due to aid constraints, there may be a hassle inside the destiny to provide all the offerings to the residents. To serve and improve the standard of dwelling of the developing population, it's essential to expand clever towns. The Smart City ambitions to make the most fulfilling and sustainable use of all sources, even as retaining the correct stability among social, environmental and financial expenses. The wireless sensors are connected to road lamps, water tanks, parking areas, dustbins and site visitors lights. Sensors are then connected to an arduino microcontroller board in which every and each essential parameters for the city are monitored and updated to cloud by way of a PC. The cloud is connected with the app server in turn that's connected to the integrated Blynk software of the consumer's Android cellphone. Here we are developing a project based on IOT. IOT is generally a sensor to sensor communication which communicates with the help of the internet.The sensors are connected together to a microcontroller over the internet to focus on five parameters of the city. Emphasis is given on how sensing and communication technologies of IOT can effectively be utilized in clever metropolis monitoring. The project aims at developing a device which facilitates the gathering of information with the assistance of interconnected modules inclusive of a couple of sensors beneficial to the city
