A smart home is a system of sensors and devices that make everyday life easier. You can use them to watch your pets while you’re away, or remotely control power and appliances. Some devices even can open this link: https://nationalcasino.com/live-casino or start downloading files you need to work, even if you are far away. Here’s how to build a smart home from scratch without spending a lot of money.
Choosing Smart Home Devices
Smart home devices range from simple timer outlets to automatic cameras with motion sensors. Popular manufacturers offer a simple set of security sensors for those who don’t know where to start. It includes:
- Wi-Fi video rotating camera;
- Smart Wi-Fi outlet;
- Window/door opening sensors;
- Smoke detector;
- Glass break sensor.
For a smart home, you need the infrastructure: the Internet, an information gathering place and a control device for sensors. At the initial stage, we suggest using the simplest solutions.
Let’s assume you have a 2.4 GHz Wi-Fi router – you probably already use it for home Internet.
The central hub where the information from the devices is collected will be the app on the smartphone.
The control device for the sensors will be a Wi-Fi socket. The sensors themselves cannot transmit information directly to the app – they simply do not have a Wi-Fi module. But they can be connected to the socket via a radio channel.
All the necessary devices have been purchased and the app is installed? It’s time to combine all the items into a system and configure it.
How to Set up a Smart Home
It takes no more than 15 minutes to set up with the app. It does not require any special knowledge, you just need to carefully read the prompts.
The first thing to do is to add a Wi-Fi outlet to the list of devices. To do this, enter the password from the Wi-Fi network, and the app will pass it to the socket.
Then you need to mount the security sensors and connect them to the control device. For installation, you can use improvised means: the lightweight opening and breaking sensors will hold a regular scotch tape. The smoke sensor is a little heavier, it must be secured with screws.
After installation, the sensors are activated by pressing a button. Don’t forget to add them to the app.
The next step is to set up scenarios and conditions. The more complex the control device, the more conditions and scenarios can be set. In our case, there are only three: apply or disconnect power, and switch the current mode.
Finally, connect the camera. This is also done through the app, and you need the Wi-Fi password to connect it.
Rotating Wi-Fi Video Camera
Wi-Fi technology allows you to create a surveillance system without laying wires. The devices are connected by a radio frequency communication module. Each of them has a unique network IP-address. Video can be viewed online or recorded to a file, including on a remote server.
The absence of wires makes it possible:
- Build a flexible surveillance network;
- Quickly add or remove additional cameras;
- Move, if necessary, the video device to another location depending on the prevailing situation without rearranging the cable installation.
Rotary Wi-Fi cameras increase surveillance capabilities by expanding the viewing angles of the monitored area. This minimizes the total amount of equipment and reduces the cost of the system.
Smart sockets are used for energy saving and accounting, automation of devices and remote control of devices. For example, with the help of a smart socket you can automate watering of the garden or vegetable garden, lighting of a garden plot or a mini garden on a window sill. The device will supply power to the connected device according to the schedule.
The simplest thing you can plug in is a heater, air conditioner, or even a small electric heating boiler. At the end of the day, you should remotely activate the outlet, then when you come home the temperature will be optimal, especially if the outlet knows how to work as a thermostat.
You can also connect a vent, recuperator, or window power outlet to the smart outlet to air out your apartment before you return.
Window and Door Opening Sensor
The window and door opening sensor is a miniature device that can be attached to a door, window, nightstand door, garage door or any other opening surface to prevent the entry of “unwanted guests” or to be aware of “unauthorized” openings of important documents, desks, or office doors in time.
The opening device consists of two miniature units – a magnetic sensor and an auxiliary magnet. The sensor includes a reed switch, an electromechanical device with contacts inside. They are closed due to the magnet acting on them. When the magnet moves away from the reed switch, the contacts inside it open and the circuit is closed, triggering an alarm.
Modern firefighting devices can operate according to different principles, and as a consequence they differ:
- Thermal, equipped with a temperature relay.
- Smoke detectors, the main working elements of which are LEDs and photocells.
- Gas-operated, having a built-in gas analyzer capable of detecting even small concentrations of CO.
- Combined, having several redundant devices at the same time. They allow you to increase the reliability of the fire alarm system, minimizing the percentage of false alarms.
Each device is connected to a fire detector, which, if detected by a remote detector, raises an alarm. The communication between the electronic unit and the detector can be established in several ways:
- With the help of wires.
- Via GSM-transceiver, working in conjunction with the control unit.
- Wireless communication via the built-in WiFi adapter.
- Through a module that gives a coded fire signal on a certain frequency.
After receiving a signal about fire detection, the electronic brain of the “smart house” automatically takes a number of preventive measures, the set of which depends on the scenario and the functions connected to it:
- Turn on the fire detector to alert all people in the house that a fire has started.
- De-energize the whole house or the room where the fire started.
- Activate the fire fighting system exactly at the place of fire to avoid flooding the whole house with water.
- Shut off the gas supply to the house.
If all measures taken do not lead to the localization of the seat of fire, the “electronic brain” with the help of GSM or WiFi will transmit an alarm to the emergency services panel.
Glass Break Sensors
The most popular glass break sensors are electronic devices that work on the principle of sensing sound waves of a certain frequency and tone.
When choosing an acoustic break sensor, the main parameters should be the type, area and thickness of the glass to be monitored. Most of the different manufacturers’ models on the market are universal devices, the memory of which contains information about the most common types of glass in construction. The thickness of glass with which the acoustic sensor can work is 2.5-8 mm. For multi-layered or reinforced glass, you need special settings or separate models of sensors.
