What are smart home sensors?

The highest level of smart home is to solve the needs of senseless, accurate, to achieve this can not be separated from the use of a variety of sensors, they are like a smart home sensory organs, by simulating the human visual, auditory, olfactory and other perceptual capabilities to receive a variety of data in the environment, such as temperature, humidity, light and so on.

There are many types of smart home sensors, including human body sensors, temperature and humidity sensors, flood sensors, air quality sensors, door and window sensors, etc. Each sensor has its unique role and function, and the following is to understand the function of various types of sensors and their application scenarios:

Human Body Sensor

Human body sensors can be used to determine the presence and activity status of the human body by sensing the heat radiation and movement characteristics of the human body, thus realizing intelligent control and application. When the presence or activity of the human body is detected, the sensor triggers corresponding operations such as turning on lights, activating alarms, controlling doors and windows, and so on. For example, when you enter the room, the human body sensor will sense your presence and automatically turn on the lights, air conditioning, curtains and other equipment; when you leave the room for a period of time, the human body sensor senses that there is no one in the room, and will automatically turn off the corresponding equipment.

Temperature and humidity sensor

Equipment or devices that can convert the amount of temperature and humidity into electrical signals that can be easily measured and processed can accurately sense the temperature and humidity of the indoor environment, and can be used with other smart home appliances to realize more intelligent scenarios linkage. For example, when the indoor temperature and humidity is too high or too low, it will link the air conditioner or air purifier and other smart devices to turn on automatically, making the indoor environment more healthy and comfortable.

Light Sensor

By measuring the intensity of light to determine the degree of light, and converting this information into electrical signals output, transmitted to the smart home system or other devices for processing and control, you can automatically adjust the working status of lighting equipment according to the set light threshold. For example, the system can automatically turn off the indoor lights during the daytime when there is sufficient sunlight to save energy, while the system can automatically turn on the lights when it is dark or when there is insufficient light to provide sufficient illumination.

Flood Sensor

Utilizing the conductivity of water, two sensing probes form a current loop when immersed in water, thus generating an alarm signal. It can be applied to the kitchen, balcony and other places in the home where there is a water source area. When flooding is detected, an alarm signal is sent, and a mechanical valve can also be linked to realize operations such as shutting off the water valve.

Air Quality Sensor

Devices capable of sensing air quality indicators in the environment can detect and measure various pollutants and indicators in the air, such as particulate matter concentration, carbon dioxide concentration, volatile organic compounds (VOC) concentration, formaldehyde concentration and so on. Through linkage with the smart home system, it can realize automatic adjustment of the working status of air purifiers, ventilation systems and other equipment to provide a healthier and more comfortable indoor environment. When the concentration of pollutants in the air exceeds a set threshold, the system can automatically turn on the air purifier or ventilation system to purify the air and provide better indoor air quality.
