Smart street light system

  1. 1. SMART STREET LIGHT SYSTEM Design Report Kuriakose Mathew Libin Thomas Midhun Shaji
  2. 2. PROBLEM STATEMENT Automatic switching of street lights considering the intensity of sunlight, brightness control of lights on detecting movement and error reporting to electric sub sections.
  3. 3. PROJECT SCOPE/OBJECTIVE Smart street light system tries to find solution for the faster depletion of energy resources due to the inefficient usage and wastage of these resources. Increasing electricity bill is something that can be witnessed by these practices. This project help to decrease the wastage of electricity by controlling the working of street light system that attributes to a good amount of electricity bills in our nation This project does not include methods to incorporate usage of renewable resources like solar energy.
  4. 4. DESIGN AND IMPLEMENTATION CONSTRAINTS Constraints are mainly in the module that regulate the brightness of the light by considering the traffic on the street at a specific time. Infrared proximity sensors are costly and at the same time maximum distance to which the sensor can sense is limited to 1 metre, which may not be sufficient for a 45 metre road.
  5. 5. DEVELOPMENT METHOD This project include three modules, the sunlight sensing and control of onoff of the lights, the traffic sensing and brightness control, error reporting system. Microcontroller used is arduino uno r3 atmega 328p ,which has to be programmed for the three tasks. Inputs for the same come from the three sensors.output include instruction to onoff the control sytems.
  7. 7. SYSTEM FEATURES/USE CASES System for controlling onoff of lights Use Case Description Sunlight intensity less than 250 lux Sunlight intensity grater than 250 lux Flow of events If the intensity is less than 250 then switch on the lights Else switch off the light
  8. 8. Illuminance Example 120,000 lux Brightest sunlight 110,000 lux Bright sunlight 20,000 lux Shade illuminated by entire clear blue sky, midday 1,000 - 2,000 lux Typical overcast day, midday <200 lux Extreme of darkest storm clouds, midday 400 lux Sunrise or sunset on a clear day (ambient illumination). 40 lux Fully overcast, sunset/sunrise <1 lux Extreme of darkest storm clouds, sunset/rise
  9. 9. FOR COMPARISON, NIGHTTIME ILLUMINANCE LEVELS ARE: Illuminance Example <1 lux Moonlight[3] 0.25 lux Full Moon on a clear night[4][5] 0.01 lux Quarter Moon 0.002 lux Starlight clear moonless night sky including airglow[4] 0.0002 lux Starlight clear moonless night sky excluding airglow[4] 0.00014 lux Venus at brightest[4] 0.0001 lux Starlight overcast moonless night sky[4]
  10. 10. BRIGHTNESS CONTROL ON SENSING TRAFFIC Use Case Description Movement detected Flow of events If there is any movement detected by the infrared proximity sensor then increase the brightness by controlling voltage from 110v to 220v Continue this for next 5 minutes then resume the previous state
  12. 12. INFRARED PROXIMITY SENSOR An infrared sensor is an electronic instrument that is used to sense certain characteristics of its surroundings by either emitting and/or detecting infrared radiation. It is also capable of measuring heat of an object and detecting motion. Infrared waves are not visible to the human eye.In the electromagnetic spectrum, infrared radiation is the region having wavelengths longer than visible light wavelengths, but shorter than microwaves. The infrared region is approximately demarcated from 0.75 to 1000µm. Infrared technology is found in many of our everyday products. For example, a television has an IR detector for interpreting the signal from the remote control. Key benefits of infrared sensors include low power requirements, simple circuitry, and their portable feature.
  13. 13. ARDUINO Arduino is a single-board microcontroller, intended to make the application of interactive objects or environments more accessible. The hardware consists of an open- source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM. Current models feature a USB interface, 6 analog input pins, as well as 14 digital I/O pins which allows the user to attach various extension boards. The Arduino board exposes most of the microcontroller's I/O pins for use by other circuits. The Diecimila, Duemilanove, and current Uno provide 14 digital I/O pins, six of which can produce pulsewidth modulated signals, and six analog inputs.
  16. 16. RISKS AND CHALLENGES •The implementation of an error reporting system to the electricity subsection is a difficult task. •The switching of the lighting system between a minimum and maximum mode is difficult.
