How Smart Technology Can Help US to Tackle the Corona Virus
2020 started with the news of corona virus pandemic starting in China. Since then the virus has reached many advanced countries and there is currently no sign of pandemic slow down or effective vaccination relief.
While everyone one of us is trying to protect ourselves and our families during the pandemic it would be a good idea to see how the Smart technology around us can help us to reduce the risk of being infected.
1- Voice Control
It’s been recommended by the WHO and health authorities to avoid close contact with others as well as touching public facility objects.
Public facility objects include lift buttons, door handles, door bells, light switches, bus stop buttons…
Voice control technology have been around for a few years and its being integrated more and more with popular Smart Home and Building Automation systems. The technology is very well capable of eliminating many of the human physical interactions with electrical and electronic control devices by establishing the interface between human voice commands and Smart control systems.
Google Home and Amazon Alexa are the two well-known voice control systems available. They could be used in the office environments and lifts to be linked with Smart home Systems Like Fibaro to stop people from touching the devices for their control inputs.
2- No Touch
Another way of eliminating human physical interaction (Touch) is using “No Touch” technology
No Touch technology is already in use in toilets to dispense hand wash liquids, operating water taps and controlling hand dryers.
Motion Sensors could also be utilised to control the lighting and open/ close doors, gates and blinds.
Gesture recognition systems also could be used to control a variety of devices like doors, alarms , lights etc.
While it’s been recommended by the authorities to stop using bank notes, the pay pass technology is helping to stop the virus spread by eliminating the bank notes.
It may also worth mentioning that RFID tags are one of the very efficient ways of eliminating direct human touch if they are used properly. One idea could be their application to replace conventional bus stop buttons!
3- Key less entry and Intercom
Like “No Touch” systems a Key less Entry (Smart Door Lock) also helps eliminating human touch, there are many Smart Door Locks available in the market which could integrate with your smart home and smartphone through Bluetooth, Wifi, Z-Wave and Zigbee protocols. Once linked everyone could use their own personal Smartphone to control the Smart Door lock.
A Combination of Smart Door Lock and Intercom system could help human to human physical contact during Quarantine period. The door could be opened or closed for the delivery person remotely while vision and voice contact is established through the intercom system.
4- Mobile App
Corona virus tracking Apps are being used in the recent pandemic to display number of infected people and their distance from the user. This genius idea helps people to maintain their distance from infected people and travel with lower risk of being infected.
5- UV Ray Sanitization
It’s been known for decades that broad-spectrum germicidal UV light, which has wavelengths between 200 and 400 nanometers (nm), is highly effective at killing bacteria and viruses by destroying the molecular bonds that hold their DNA together. This conventional UV light is routinely used to decontaminate surgical equipment.
According to the latest guideline on the diagnosis and treatment of the novel coronavirus released by the National Health Commission, the Corona virus is sensitive to ultraviolet light and heat, so ultraviolet radiation can effectively eliminate the virus.
According to the guideline, indoor spaces should be disinfected with ultraviolet light with an intensity of over 1.5 watts per square meter. A UV lamp can disinfect objects within one meter for at least half an hour.
Longer exposure to radiation is needed when the temperature indoors is below 20 C or above 40 C and relative humidity is over 60 percent.
UV light could disinfect all materials including, shopping bags, mobile phones, clothing, cars interiors, rooms, …
Smart Home system could be used to control the timing to ensure the adequate level of exposure is met as well as remotely controlling the UV light to avoid human exposure.
Although UV is effective in killing the virus indoors, UV lamps should not be used to sterilize hands or other areas of skin, as the radiation can cause skin irritation and even skin cancer.
Also a by-product of UV and Oxygen is Ozone which could irritate our respiratory system. It is recommended wait for a while before entering the UV treated room for the Ozone to decompose.
The UV exposure timing and the Ozone decomposing time depends on the UV light power and exposure duration. Smart Home system could be programed to time the UV light and turning the ventilation fan on after the UV exposure to help the disinfection process be carried out safely.
