Automatic Street Light Project Ppt Free Download !!HOT!!

do you know what is the main reason of flickering that is the light which is on the load feedback the LDR that's why an error-full control system will created automatically.you need to separate the light source from your LDR.LDRshouldn't response on it's own circuit load and of-course you need to add relay or traic with very little labor to make it a strong circuit..BEST OF LUCK :)

It is very helpful for beginners like us. Thax a lot for sharing. Bro kindly provide a simple circuit, I need to control street light 220 v with using LDR. In sunlight my street light turns on & at night turns off automatically, for that kindly provide a circuit.

Super.Now a days in solar streetlight systems some peoples are using voltage based Controllers.Is this right( i meant it voltage sensors).

If this is right please furnish the details about this type of circuit diagram.

It'd be very simple actually. Swap out the low wattage components used in this example with some higher wattage ones, replace the battery with a 120/6 volt transformer + a rectifier and filter capacitor & put the coil for a contactor that would switch the mains power for the street light on and off in series with the transistor.

The circuit would be almost identical to the

Brilliant post! You explained everything quite intelligently. I will follow all the steps for automatically turning ON and OFF my garden lights, or I will simply forward this blog , thank you! You were a great help.

Uses : We can use this circuit as a street light because it will automatically ON and OFF.In the morning when light will come on the LDR then LED will not glow and in the night light will not be fall on LDR then LED will glow in the night and vice versa.

Majunsha went to Oslo of Norway, which was the first city to install citywide automatic street lights. She was surrounded by family and friends to discuss not just her travel experiences but also to know more about smart street lights, Light sensors, LDRs, and IoT.

Same is the case with automatic street lights. An automatic street light is the one which adapts to the surroundings be it environment or vehicle movement. According to the surroundings it may turn on, go off, dim down or brighten up.

For cities looking to invest in smart technology, intelligent street lighting offers the chance to reap outsized benefits for a relatively small investment. In its simplest form, networked LED lighting promises to lower energy costs by using motion detectors to provide illumination only when needed. Beyond energy efficiency and advanced lighting capabilities, city planners looking to harness data-driven intelligence can use networks of smart street lights as the foundation on which to build powerful smart city applications.

Smart street lights can be outfitted with a vast array of sensors and cameras to collect critical data, help cities make well-informed decisions, and improve city useability for residents. On top of the Internet of Things (IoT), street lights can communicate with each other wirelessly while monitoring traffic conditions, tracking maintenance updates, alerting officials to potential security risks, and more.

Navigant Research estimates that by 2023, there will be 116 million LED street lights in use, one for each HPS fixture. These smart lights will help cities reduce electricity costs, lower CO2 emissions, and improve maintenance. With auto-dimming, scheduling, and a host of other capabilities, cities could see a 50-75% reduction in energy costs via smart street lighting.

But energy efficiency is just the beginning. Air quality monitoring, traffic control, accessible public wi-fi, security cameras, gunshot detection devices, and digital signage/advertising all represent viable candidates for implementation into urban street light infrastructure. Public safety applications could reduce crime up to 10%, according to Silver Spring Networks.

Los Angeles has installed smart street lights on 80% of its roadways. These connected lights feature LED bulbs and 4G LTE wireless connectivity, as well as sensors capable of detecting gunshots and other threats to public safety. In the first year alone, LA has benefitted from a 63% reduction in energy costs in addition to improved city-wide cell service.

Fortunately, the payback for smart street lights is faster and higher than most other smart city initiatives, with most reports estimating cost reductions of 70-75%. The switch to LED bulbs provides substantial (and highly measurable) short-term ROI, which paves the way for the simultaneous implementation of technologies with longer paybacks and hard-to-capture ROI like real-time traffic monitoring.

When a vehicle comes into the range of the sensor, it does some mathematical calculations to determine the distance between the vehicles and sensor, if the vehicle is confirmed to be below the pre-determined range; the on-board microcontroller will light the street lamp at maximum brightness.

The automatic street light dimmer circuit consist of Arduino which is the brain of the project, an ultrasonic sensor for detecting vehicles or human beings. A 9V regulator is provided for powering the arduino microcontroller board and a MOSFET for driving the LEDs which consumes few amperes at peak brightness.

The ultrasonic sensor is elevated around 3.5ft to 4ft above the ground; this is done so that it only detects vehicles and human beings, since their average height is around the same and when dogs or cats or any other animals which usually roam around the city will not trigger the street light to maximum brightness.

More and more cities across the globe are adopting smart street lights. After all, with just a marginal upfront investment, the benefits of smart street lighting are apparent. If you are upgrading your public lighting infrastructure, this article gives insight into some of the notable benefits of motion sensor street lights.

The coverage area, direction, sensitivity, delay, hold time, and light rate up and down time, can all be configured through a central management system. Which corresponding street lights should brighten up, when a human is detected, can also be set via a central management system.

A street light motion sensor is a perfect solution. It keeps the street lights at low intensity, for example, at 20% when streets are vacant. As soon as the sensor detects a human, it triggers the street light (and neighboring street lights) to turn to, for instance, 80% or 100% intensity.

By dimming the street lights when no one is around, motion sensors prolong the life of luminaires. With the life of luminaires extended, they will need to be replaced less often, and maintenance crews will spend less time replacing burnt-out lights.

Motion sensor street lighting can play a huge role in reducing light pollution. These smart lights automatically brighten only in the presence of a human. When there is no one around, they remain dimly lit, reducing the sky glow and light pollution, as well as energy waste.

With motion sensor street lights, which offer light-on-demand, cities, and municipalities can significantly reduce their energy waste and ultimately their carbon footprint. The Dutch Island, Texel, presents an excellent case where how using motion sensor street lighting, it is able to become energy neutral.

Street lights with motion sensors offer on-demand lighting. In other words, street lights brighten only in the presence of a human. When there is no one around, street lights remain dimly lit. This reduces light pollution remarkably, greatly benefitting nocturnal wildlife.

Through motion sensor street lights, it is also possible to change the color, temperature, and intensity of street lights! Color-changing street lights are specifically beneficial for bats, moths, fireflies, and even migratory birds and turtles.

Smart streetlights, also known as intelligent or networked street lighting, are a technological advancement in urban infrastructure. These innovative lighting fixtures are equipped with sensors, wireless connectivity, and advanced technologies, enabling them to interact intelligently with their surroundings. These sensors can monitor everything from air quality and noise levels to traffic flow and pedestrian movement. With this data, city officials can make informed decisions to improve the overall efficiency and livability of the city.

Often integrated with the Internet of Things (IoT), smart streetlights can communicate with other devices and systems, creating a network of interconnected infrastructure. This connectivity enables them to respond dynamically to changing conditions, such as adjusting their brightness based on the presence of pedestrians or vehicles, optimizing energy consumption, and enhancing overall safety. Moreover, these intelligent lights can monitor air quality, detect noise levels, and provide data on traffic patterns.

Smart streetlights have numerous nodes, or sensors, to detect various data points. They can share this data with each other and a remote central control system via a wireless communication network. Examples of communication networks are detailed further on; however, radio frequency and cellular are the most popular. This data allows lighting to be monitored or adjusted in real-time according to various needs.

These innovative lights are not only energy-efficient and cost-effective, but they also utilize advanced communication technologies to enhance their functionality. Here are some of the types of communication technologies that smart streetlights use:

Smart city light fixtures are equipped with a wide range of sensors to collect and analyze data in real-time, allowing for smarter and more responsive street lighting systems. Some of these sensors include:

Funding smart streetlights requires careful consideration of various financing options and strategies. A few options include public-private partnerships, grants and subsidies, leasing agreements, or municipal bonds. However, intelligent street lighting can also be installed as part of an energy savings performance contract without any upfront capital. This flexible funding alternative helps cities, towns, counties, and state governments use energy savings and avoid capital costs to pay for improvements. As a result, no up-front capital is required. Projects are financed and repaid with guaranteed energy and efficiency savings from the newly installed equipment. 006ab0faaa
