Smart home sensors: Can you control your apartment?
Nowadays, Internet of Things technologies allow people to make their dwelling place not only comfortable but also smart. It can be implemented using various sensors connected to controllers and providing security and comfort. Let’s discover what a smart home means and how smart apartment sensors operate.
What is a smart home?
A smart home is a set of solutions allowing to automate household equipment. A smart apartment allows its owner to control lamps, sockets, and electrical appliances. Besides, the control system is based on various special sensors.
Smart home sensors
There is a huge amount of smart home sensors. They can be conventionally divided into two categories: motion sensors and environmental parameter sensors.
Motion monitoring sensors
Such sensors are applied in security systems and for lighting control. They monitor several zones at the same time as well as respond to motion and object presence.
Motion sensors follow changes in infrared and ultrasonic fields. Presence sensors are based on the same technology, but they are more sensitive to parameter variations.
However, it is difficult to design a smart lighting and climate system using only these sensors. There is a certain problem: if a person is motionless for a long time, sensors stop recognizing the presence.
This challenge can be solved using a photoelectric sensor, which is installed in the doorway and is able to remember the amount of people in the room.
Environmental parameter sensors
Smart home sensors able to assess the environment allow to control its parameters, monitor security, and make a room more comfortable.
An exterior temperature sensor responds to weather changes and informs the system of an outside air temperature. Relying on the obtained data and analyzing the forecast of the home meteorological station, the system determines the best possible heat and ventilation performance in the apartment in order to keep a comfortable temperature in the room at any time of the year.
A gas detector informs smart home owners of gas pipeline issues: it gives a signal and sometimes can stop fuel entry.
A fire suppression gauge recognizes smoke and responds to the temperature jump: in this case, it informs apartment owners of the problem.
A humidity sensor will respond to heating issues and leakage. The latter one can be eliminated using a special sensor that will turn off the tap valve.
A variety of smart home sensors make the apartment safe by reporting on the first signs of defects and provide coziness by controlling comfort parameters and adjusting them to human needs.
