The next episode of “How IoT can solve everyday problems” focuses on the Outdoors
IoT lights can monitor air quality
Environmental sensors embedded in exterior and street lighting can build up a picture of air quality and allow municipalities to take real-time measures to reduce local pollution.
IoT lights can alert police to gunfire
Special microphones in street lights can detect gunfire and, via triangulating software, tell police immediately of the discharge of a firearm and its location.
IoT lights can help with planning for bad weather
Sensors embedded in street lights can monitor snow build-up and water levels, meaning municipalities can prioritise responses such as snow ploughs and gritting trucks.
IoT lights can predict when a street lamp or driver is about to fail
Predictive maintenance software linked to smart street lights can inform municipalities of when lighting equipment will need replacing, rather than reacting to individual outages as they occur.
IoT lights can assist with refuse collection
Battery-powered sensors in refuse bins can talk to nearby IoT street lights, telling refuse collection teams where they are and when they need emptying, while software plans optimal routes.
THE FOURTH INDUSTRIAL REVOLUTION MENTIONED IN THE STATE OF THE NATION ADDRESS AND BY MINISTER PATEL TODAY 19 FEBRUARY 2018
Those of you are students will recall that I sent this out in an E-mail on 19 February 2018. I feel so strongly about this that I decided to include it in the Newsletter which has a much wider readership.
I am sure that most of you followed the recent events closely and hopefully, you also listened to the New Presidents address.
He referred to the fact that government has taken note of the Fourth Industrial Revolution and will actively address all opportunities for South Africa to be an active player in that space.
Today, Minister Patel, the Minister of Economic Development stated that the greater spectrum of bandwidth for connectivity will be freed up and they will focus on the development of disruptive technologies to keep pace with the rest of the world and to take the lead wherever possible.
You will all recall that the article that I wrote on this subject. I have repeatedly urged you to read and keep abreast of the many disruptive technologies some of which abound in the lighting environment such as Power over Ethernet ( PoE, a disruptor of note which will result in IT specialists doing the installation with an estimated 70% to 80% saving). Visible Light Communication (VCL, includes luminaires with the ability to provide connectivity either by Wi-Fi or Li-Fi. If at Li-Fi connectivity that provides up and download speeds from 1GBPS to 100GBPS – mind-blowing) and Indoor Positioning Systems (IPS, used by supermarkets to guide customers through shops in the shortest time according to the shopping list loaded on their smart devices, loyalty points updated and payment deducted without passing a cashier. We have used the Carrefour application when we have visited Spain. Also used by shopping malls instead of the touch-screen information screens, in museums and galleries as digital guides which we enjoyed in Toledo at a cathedral and in the National Museum of Archaeology in Madrid) Yes, these are already in use and some will soon be introduced by some of South Africa’s major retailers. Then there is Human Centric Lighting (HCL, it is a reality, I have recently visited consultants in Durban who have asked for this for a project). Finally, there is Smart City Street Lighting (makes it possible for precise control over street lights in areas, along routes, etc for different settings for different conditions, more fault reporting, accident reporting, Wi-Fi or Bluetooth Mesh connectivity, CCTV and more.
We cannot afford to sit back and relax. It is another prompt for us to be make sure that we are always at the top of our game.
Researchers Prove UV Light Can Kill Flu Viruses Without Harming Humans
I never ceased to be amazed at how much there is still to learn about the human eye, vision and light. I find that I am compelled to read everything that I can possibly find about the subjects and more.
I am sure that you will also find this next article fascinating and that it will give you all another take on the benefits of light and lighting.
Far-ultraviolet C (far-UVC) light can kill flu viruses and placing it in spaces like hospitals, airports, and schools could reduce the incidence of flu infections, according to a new study.
The far-UVC light does not damage human tissues. It has been known for a while now that broad spectrum UVC light has the power to kill bacteria and viruses by breaking molecular bonds.
This light is also used to sterilize surgical equipment. However conventional germicidal lamps using broad-spectrum UVC light are not safe for humans to be around. They can cause skin cancer and cataracts in the eyes with prolonged exposure.
“Unfortunately, conventional germicidal UV light is also a human health hazard and can lead to skin cancer and cataracts, which prevents its use in public spaces.” said a study leader David J. Brenner, director of the Center for Radiological Research at Columbia University Irving Medical Center.
However, this study did not use broad-spectrum UV light, it used far-UVC light, which is a narrow spectrum of radiation.
“This type of UV is also effective against illnesses and has a very limited range and cannot penetrate through the outer dead-cell layer of human skin or the tear layer in the eye, so it’s not a human health hazard,” Brenner said in the study.
Far-UVC safe for humans
Until recently conventional UV-light was only really practical when people were not around. The Columbia team came up with a possible solution about five years ago. Light on the far end of the UV-C spectrum, known as far-UVC, has very short wavelengths. The researchers, led by Brenner, suspected it can penetrate and destroy microscopic bacteria and viruses. They discovered that it cannot travel through the protective outer layers of human skin or eyes.
“We wanted to get all the benefits of UV light in terms of killing microbes, but none of the health hazards. We haven’t seen any biological damage to skin cells or eye cells, whereas with conventional UV light we’ve always seen lots of biological damage,” Brenner said.
Earlier studies have shown that exposure to far-UVC light does indeed appear to be safe. In their new study, Brenner and his colleagues released aerosolized particles of the H1N1 seasonal flu virus into a test chamber and exposed them to very low doses of far-UVC light. The light inactivated the viruses with about the same efficiency as conventional germicidal UV light. A control group of bacteria not exposed to light remained active.
Brenner and his colleagues have thus shown that UVC light can effectively kill airborne influenza.
Deadly flu bouts
In the US, this year has been accompanied with an especially deadly flu season. It is forecast to be more deadly than the Swine Flu of 2009-2010, killing about 4,000 people a week.
Researchers continue to work to better understand and explain flu and are working on more effective and accessible treatments. The study on far-UVC light very low doses can inactivate flu viruses, but the results still need to be recreated and explored in a variety of settings.
However, this finding can be a powerful tool if it is confirmed that this type of light can kill flu viruses without causing any human harm. This could mean that overhead lights could be placed in medical facilities, public spaces, and even homes which would act to wipe out exposed viruses, stopping them from spreading and infecting new people.

In next month’s newsletter
- The final episode in the series “How IoT can solve everyday problems”. It focuses on the Hospitality environment which is already a reality both here and to a much greater extent overseas.
- Dementia Care facilities. Dementia is certainly not a new social ailment, however, it is particularly concerning that it is now far more prevalent in our modern society which is ascribed to a variety of reasons and causes.
Until April, have a wonderful March 2018!
