Smart Street Light spotlights different restrictions and difficulties identified with traditional and old street lights that are confronted nowadays and the answer for the deal with those issues by embracing the vision of a bright street light. Smart street lights are vitality effective as well as extremely dependable. The primary thought in the present field advances is computerization, power utilization, and expense adequacy. Automation is implied for the decrease of labor as the human has gotten to be excessively occupied and even incapable, making it impossible to discover time to switch the lights. Two sensors viz. The light-dependent resistor (LDR) and GAS SENSOR MQ135 sense the brightness in the surrounding environment and automatically control the intensity of street lights accordingly and detects the presence and concentration of various hazardous gases and vapors such as toxic or explosive gases, and volatile organic compounds. Here I have utilized an Arduino Uno to control all the commands from LDR and gas Sensor and execute them legitimately. Fundamentally it acts as the mind of the entire framework.

PROBLEM STATEMENT

Disadvantages of Classical Street Light

• Street lights remain on when there is a visible spectrum of light.
• These street lights need a manual switching operation.
• lt also needs manpower.
• These street lights are unnecessarily glowing with their full intensity in the absence of any activities in the street.
• High power consumption and waste of energy.
• Less reliable. Manual hectic operation due to change in season and climate.

To face the various problem mentioned above in the conventional lighting system we need a lighting system that is well equipped with recent inventions and technology. As it is well known to everyone is that the natural sources to generate power is limited and we are wasting so much energy meaninglessly. So if we can use automation in this particular case so that all the street lights can be switched on and off automatically when it is really necessary. And if we can use controller circuits to implement a model so that all the street lights can only glow with their maximum intensity when there is an activity in its region otherwise it should glow at a minimum given intensity. So that we can save a huge amount of power. With the inventions of light-emitting diodes which have a small amount of power consumption and high efficiency, we should use light-emitting diodes instead of all classical fuse bulbs.

Day to day, the level of Air pollution is increasing rapidly due to increased industries, factories, and vehicle use which affect human health. So here we have additionally designed a device/system which can measure air quality around it and monitor air pollution levels. According to a WHO report, each year 2.4 million people lose their life because of breathing disorders that originate from air pollution. Polluted air might affect the human heart, lungs, eye, nose, throat, and skin, leading to disorders such as breathing trouble, lung cancer, bronchitis, and pneumonia.
