The "Smart Home" system is an automated network consisting of individual devices and devices, each of which is responsible for solving any household or economic problems. As a rule, the ideology of managing such a system uses modern technology of distributed intelligence. It does not require the presence of a main computer that controls the operation of the entire system, because each of its nodes has its own intelligence. Receiving information from sensors located throughout the house, such a unit quickly processes it and generates control signals, which then go to the actuators. If you integrate them into a single centralized network, the sensors are controlled from a centralized control panel common to all devices.
Sensors for the "Smart Home" system
Sensors are one of the important elements of an intelligent system. Many of them are capable of working offline and do not require integration into a single network.
Movement
Motion sensors are most often used when you need to automatically turn on and off the light. Motion detected - the light turned on, no movement - turned off. They are installed in utility rooms, bathrooms and corridors, in the courtyard - here, when motion is detected, a searchlight will turn on. The devices are also used in security systems - when movement is detected in a room taken under protection, the sensor will notify the homeowner or transmit a signal to the security console.
DDs are wall and ceiling. A wall-mounted version is used to turn the light on and off. If the sensor is integrated into a security system, it is better to purchase a ceiling version with a 360 ° view.
Temperatures
The temperature sensor transmits the necessary data for Smart Home systems with climate control function. They are connected to the system together with heating devices, air conditioning and the "Warm floor" subsystem. With their help, you can maintain the desired temperature in all living areas.
Also, temperature sensors are used for automatic heating of street steps, courtyard paths, etc.
Lighting
Lighting sensors work, as a rule, in lighting systems of adjoining territories (they turn on lights at nightfall and turn them off at dawn), when organizing facade and landscape light. Indoors, they are used, for example, to curtain windows and turn on lights in the evening.
Fire-fighting (smoke)
It is recommended to install a smoke detector in every residential area. When smoke appears, it emits a sound signal, thereby attracting the attention of people in the house. If the fire detector is connected to the security system, it will send an alarm signal to the dispatcher's console and turn on the fire extinguishing and smoke removal systems, de-energize the house and turn off the gas. A sensor equipped with a GSM module will notify the owner of an emergency by sending the latter an appropriate SMS.
Magnetic contact (reed switch)
Reed switches are widely used in smart home security systems. Install them on doors, windows, gates, etc. The principle of their operation is simple: in the normal state, the sensor contacts are closed, when the contacts open, an alarm is triggered.
Reed switches integrated into the centralized network of a smart home help save energy.For example, if an air conditioner is running in the room and a window is open, the reed switch will turn off the air conditioner and turn it on only after the window is closed. In winter, if the doors and windows are open, the reed switch will turn off the heating.
Leaks
The leakage sensor is a small device (5x5 cm), which is placed a few millimeters from the floor or completely on the floor near the washing machine, under the radiator and in other places where water leakage is possible. If liquid gets on it, the owner will be notified of this by sound or light signal.
By connecting such a sensor to the Smart Home network, which has a controller and valves that shut off the water supply, the problem will be solved without the presence of the home owner. The system will send SMS about the occurrence of an emergency to the owner and the dispatcher of the company serving the house.
Additional detectors
- The CO2 sensor is installed in garages, boiler rooms and in houses equipped with air purification systems.
- The domestic gas sensor monitors the level of methane in the apartment and, if its concentration limit is present, shuts off the gas.
- Sensors for rain, wind and soil moisture are used to monitor the backyard. They will monitor the amount of moisture in the ground and, if necessary, include watering the plants. In addition, the system, having received a signal that a rainstorm is approaching, will close the open windows and send a message to the homeowner.
Installation, assembly and adjustment of sensors must be carried out in accordance with the instructions attached to them. Only in this case their work will be efficient and trouble-free.
Sensor manufacturers and software for their configuration
- Hank;
- Philio;
- MCO Home;
- Neo Coolcam, etc.
All of them differ in miniature size, which allows them to be placed in residential premises almost invisibly. Fastening is carried out with a screw or double-sided tape.
Devices are:
- analog;
- wireless;
- multifunctional.
To configure the detectors and control them as part of the Smart Home system, specialized software is used:
- Major DoMo;
- Home Sapiens;
- Smart Home 1.0;
- DIVISION Constructor, etc.
All executive mechanisms of the "Smart House" system and household appliances connected to it are switched on and perform the functions assigned to them when certain commands are received. The collection of such commands is called a script and is programmed separately. This procedure usually takes a lot of time and requires special attention, because the efficiency of the entire system depends on its quality.
