A real-world proven solution for dynamic street light control and management which relies on an open and flexible Internet of Things architecture. Automatic street light system is smart and provides a safe night time environment for all road users including pedestrians. The Street light Automation system can reduce energy consumption and maintenance costs and also helps to reduce crime activities up to certain limit. The automatic street light system is mainly decided on the combination of sensors technology. This system would provide a remote access for streetlight maintenance and control. In addition environmental monitoring is needed to be able protect the public and the environment from toxic contaminants and pathogens. It is used to prepare environmental impact assessments, as well establish the circumstances in which human activities carry a risk of harmful effects on the natural environment.
A smart street light basically serves as a network node to receive, collect and transmit information through various wireless or wired communication networks by making use of sensors, actuators, communications modules and processors embedded in LED lighting systems. With the availability of various sensors, such as PIR sensors, hall effect sensors and LDR (light dependent resistor) sensors, the operation of the large number of fixtures can be coordinated across an entire installation over wide geographical areas.
The remote, dynamic control of street lights enables a whole new class of functionality, including remote dimming, self-diagnostics, smart scheduling, remote shutoff and emergency control, resulting in considerable reduction in maintenance and energy costs. IoT offers advanced connectivity and innovative inter-operability among devices and systems. The IoT based smart lighting infrastructure introduces tremendous new capabilities to create new insights and actionable information from massive streams of real-time data. The street light poles can be designed to accommodate multiple sensors and devices such as weather sensors, pollution sensors, traffic volume sensors, parking sensors, video surveillance cameras, RFID devices, GPS modules, and wireless access points. Environmental monitoring is important not only in measuring the effects of industrial and personal human activity, but also in changing people’s habits to reduce their environmental impact.
Consumer access to the data collected by continuous monitoring of air and sound quality can enable people to change their behavior, for example, reducing their personal carbon footprint, or selecting transport modes that will reduce their exposure to pollution.As well as passive monitoring, environmental sensors also have a key role to play in reducing the harmful impact of industrial activity on the environment.Careful monitoring of air and sound quality in park facilities can provide alerts for pollution in air and vehicle exhausts that would release harmful emissions into the environment, or before exposure limits are exceeded. Such alerts allow preventative actions to be taken in a real-time basis, and decisions and actions are increasingly being automated. Our technology is enabling better than- ever measurements of trace amounts of pollutants, creating awareness among the public to safe guard the environment.
