Written by Mark Bigolo, Vice President of Internet of Things, Wireless and Sensing Products Group, Semtech In 1970, 20 million Americans gathered together on Earth Day for the first time to celebrate clean air, earth and water. Today, more than a billion people around the world congregate every year on April 22nd to show support for environmental protection, celebrate planet Earth, and raise awareness about pollution and climate change. As people all over the world struggle to return to normality amid one of the most challenging years in recent history, the theme of “Reclaiming Our Earth” on Earth Day 2021 seems more influential than ever. Covid-19 forced people everywhere to stay indoors, and the environment benefited, resulting in improved air quality, cleaner rivers, less noise pollution, and a quiet and peaceful wildlife. But what happens to our land when those restrictions no longer apply? With the end of the epidemic approaching and the resumption of daily activities in sight, the emphasis on environmental awareness and individual health is crucial. From monitoring air quality to water consumption, IoT solutions continue to play a fundamental role in helping protect our planet and even citizens from the environmental dangers that may come our way, especially if no action is taken. Smart Home Appliances As we close to returning to normal daily activities, people will frequently leave their homes for the first time in nearly a year. Solutions that support IoT with the ability to connect smart home devices to the same platform can enhance data monitoring to reduce power when people are outside the home. These IoT-enabled devices, such as a smart thermostat, sprinkler or outlet, are important for energy conservation in the home, as they provide real-time data on energy use and an actionable way to contribute to change, all without having to consider controlling Settings manually. For example, the smart thermostat automatically adjusts the temperature of the climate control equipment in the home according to the preference of the homeowner, and the smart outlet allows a person to turn on or off electronic devices remotely from their cell phone. Energy Conservation Of all the ways in which each of us can make a meaningful difference in preserving our Earth, energy conservation is at the top of the list. Energy conservation is a necessary step to take to restore our planet, and although it can be as simple as turning off the light when leaving the room, reducing the use of devices, or even just walking to work, adopting smart home solutions and spreading IoT technology can It makes energy conservation and sustainability an easy process. Energy conservation doesn’t just apply to the steps you take while at home; It is also closely related to companies and institutions. By equipping buildings with sensors, companies and property managers can use their space more efficiently by reducing energy and water consumption, controlling building temperature, and much more. Real-time data collection and analysis by IoT sensors play a fundamental role in improving building energy efficiency and sustainability in the workplace or warehouse. Environmental Monitoring Utilizing IoT connectivity sensor networks for environmental monitoring can help combat climate change and create a more sustainable environment. Long-range, low-power sensors spread across a farm, city, or forest can monitor a variety of factors such as air quality and water use. Sensor networks can also help prevent deforestation, prevent endangered species, and more. In doing so, potential problems are identified and reported before they get worse. By collecting data, appropriate action can be taken with regard to water, air or any other pollution affecting health, conserving biodiversity, and much more. Despite the fact that our daily life is returning to normal, the environmental improvements we have seen over the past year could continue to make progress. With all of us taking a stand in the fight to reclaim our land on this Earth Day, IoT technology is one of the ways we can start making a difference in our daily lives. Cover photo: Pixabay.
