At least two thousand working satellites are plowing the space in the Earth’s orbit. This is already taking into account the star project of Elon Musk, who launched 60 satellites back in 2019. The responses were contradictory, but as a result, the world received a global Internet, and that allowed us to improve our everyday life. Here we can provide the automating your home space.
Home Automation, Not a Dream Anymore
The Internet has allowed us to manage our homes without even being there. We easily began to manage the utilities and functions there via the Internet to make life more convenient and safe. Additionally, and in a sense, this even allowed us to save money. For example, you can save on energy bills by reducing the time the light stays on, or by lowering the temperature when you leave a certain room.
To maintain a certain temperature at home, to cook dinner by a specific time, to start the vacuum cleaner to clean the room for our arrival, to look into the cameras if there is something suspicious near the house, in case of a danger to lock the front door, to open the window for ventilation, to set up smart speakers to play music, to find out about emergencies like a leak in the washing machine or smoke in the room – all this is just part of the list that can happen in your house without your physical efforts and due to automation of your home space.
Gradually, this became a necessity, and Smart Homes began to appear on the planet more often than mushrooms after rain. Every device is equipped with sensors, connects via Wi-Fi. You can control them from your smartphone or tablet, being at home, or many miles away. But if the Internet is the brain of home automation. Then what is its heart?
Metal Heart of Home Automation
The home automation system consists of three main elements: sensors, controllers, and actuators. Fully automatic execution of the Smart Home scenario usually looks like this:
- The sensor sends a signal to the controller
- The controller interprets the received data with the current program and gives a command to the performers
- The actuators execute the order from the controller, performing some action.
That is, after receiving a signal from the controller, they perform various actions – turn on the light, control the power supply of household appliances, raise and lower the curtains, block the water, and can do much more.
For this reason, we call the actuator the heart of Home Automation. It physically acts on the controlled object, and the main task of this mechanism is to transfer forces from the control device to the executive. The term “actuator” is based on a simple principle of energy conversion. Even before getting acquainted with this definition, each of us had to deal with actuators. They were used in agriculture, construction, automobiles, and everyday life.
Actuators differ from each other in the method of energy transfer. The controlled object can be driven by a rotating or linear action. Quite understandably, the demand for linear actuators began to grow, especially this trend began to manifest itself noticeably in California.
Actuators in Action
Here are some examples of the usage of actuators, providing a deserved comfort in your home. You decide to see if your pets are naughty while you are working in the office. But what bad luck, it is not observed from the camera’s spot, where you installed it for the last time. So, if the actuator had not happened in the chain of automatic execution of the Smart Home’s scenario, you would never have been able to move the video camera. Next case.
You came home and accommodated comfortably on the couch to watch TV. Tiredness from a busy day forces you to change your position to a recumbent one. But now you have to look at a different angle and you don’t want to get up. Fortunately, various devices come to help, and the presence of an actuator there allows you to adjust the position of the TV as it is convenient for you. Life has never been so comfortable!
