Smart LED Streetlamps system through the implementation of mesh networks by hector_bracamontes

Dear hbraca, Thank you for your submission and congratulations on being selected as a finalist for the final judging round. We thought that your proposal was strong because it was specific and actionable. On that note, however, our advice for the final round would be to add as much as you can in the sections on the cost and timeline, since we would be very interested to see more details on how this plan might become a reality.

If you specify amber "turtle safe" LEDs -- which are much like the amber sodium lamps -- you'll save money on the hardware, save money on the electricity, and avoid the problem from adding more of the wrong color light to nighttime. www.ama-assn.org/resources/doc/csaph/a12-csaph4-lightpollution-summary.pdf "Low levels of illuminance in the blue or white fluorescent spectrum disrupt melatonin secretion." "White" LEDs are like "white" fluorescents -- both of them produce bright blue light inside a coating of fluorescent material that re-radiates the energy. But significant blue gets through. Also, the white LEDs need higher voltage to run, that costs more (and they are priced higher if you compare) You have or will have good healthy night lighting anywhere sea turtles nest along the beaches now -- get quotes on those lights, and you'll get the health benefit for people. Here's one supplier I've known about for a while: http://www.lsgc.com/fixtures/sea-turtle-friendly-led-fixture/ The same wavelength -- 400 to 500nm, blue-green -- affects people and turtles (and much else). "... in February, a new Mexican law (known as Official Norm-162) took effect, and it offers a whole slate of new protections for sea turtle nesting grounds in Mexico.... Putting Out Artificial Lights The regulation also addresses one of the main factors that disrupt nesting turtles: artificial lights from houses, hotels and roads. These light sources can not only disorient nesting females, but they can be lethal to emerging hatchlings. As they climb their way up from their sandy nest, newly-hatched turtles look for the subtle light reflecting off the surf and waves to orient themselves towards the sea. Artificial lighting can point them in the wrong direction ...." http://www.defendersblog.org/2013/04/mexico-protects-sea-turtle-nesting-habitat/

Thank you all for your comments and support. Applications for mesh networks are numerous, we mention some: Electric meter reading, gunshot monitoring, street surveillance, public information broadcast, street parking monitoring, traffic monitoring, traffic signal control, streetlighting control and pollution monitoring. The applications implementation would depend on the actual municipality needs. Public lighting represents 60% of energy consumption in many municipalities in Mexico and there are around 6 million streetlamps within the country. Thus, public lighting is considered a main concern of municipalities in terms of energy consumption. Nowadays, the streetlamps are controlled with photocells but a lack of preventive maintenance and staff make them susceptible of failing. Therefore, a telemanagement system is a good option for managing the public lighting and reducing energy consumption from streetlamps, as well as maintenance (e.g. fuel, spare parts).
