Building Automation System (BAS, Building Automation System) is one of the main components of intelligent buildings. The intelligent building realizes the comprehensive monitoring and management of the equipment and the building environment in the building (group) through the building automation system, and creates a comfortable, safe, economical, efficient and convenient working and living environment for the users of the building. management and reduce operating costs. The building automation system involves equipment and systems such as electricity, lighting, air conditioning, ventilation, water supply and drainage, disaster prevention, safety precaution, and garage management. Its design level and engineering construction quality have a direct impact on the realization of intelligent building functions.

The role of building automation system

Real-time monitoring to avoid accidents

The computer system monitors the mechanical and electrical equipment and the building environment in real time, and monitors the hidden dangers that cannot be found by manual workers at any time, so as to make up for the lack of manpower and avoid major losses.

Meet comfort requirements

Automatic indoor constant temperature and humidity control to ensure proper temperature and humidity, providing a comfortable environment for employees and customers; automatic delivery of fresh air to ensure fresh air and reduce office syndrome; humanized intelligent lighting control, allowing work More convenient.

Scientific management to reduce costs

Through the automatic monitoring and effective management of the mechanical and electrical equipment in the building by BAS, the normal operation of the equipment can be maintained with the least energy consumption and energy saving.

Through the regular management of the equipment, the service life of the equipment is prolonged and the maintenance cost of the equipment is saved.

The BAS system greatly facilitates the operation and maintenance of equipment, greatly improves the work efficiency of maintenance personnel, and reduces the labor cost of enterprises.

The main function of the sensor in the building automation system is to make the whole building safer, energy efficient and comfortable. The carbon dioxide sensor, like the temperature and humidity sensor and other sensors, belong to the bottom layer. They send their measured values ​​to the data collector through digital or analog signals. After that, it is transmitted to the central processing unit through the data collector. The central processing unit then controls the actions of each device through the controller. Through the central processing unit, the main function of the carbon dioxide sensor is to regulate the amount of fresh air in the building to keep the indoor air fresh. Save energy consumption of air conditioners and ventilators.

Infrared carbon dioxide sensor for low power HVAC

British GSS infrared carbon dioxide sensor (NDIR CO2 sensor) COZIR-A can effectively detect indoor carbon dioxide concentration

The carbon dioxide sensor COZIR-A is a high-performance CO2 sensor with ultra-low power consumption (3.5mW), which is ideal for battery-powered products and portable devices; based on IR LED patented technology and innovative optical path design, the carbon dioxide sensor COZIR Become the lowest power NDIR sensor; and optional temperature and humidity output. The carbon dioxide sensor COZIR is the third generation product of GSS, the leader in IR LED CO2 sensing technology.Three optional ranges are 0-2000ppm, 0-5000ppm and 0-1%, which makes COZIR-A carbon dioxide sensor more suitable for building automation (HVAC) and agricultural greenhouses

For most occupants or users, people are happy with the conveniences that smart buildings can provide. But for investors: how much can we save? How much money do you have? How long does it take for the investment to pay off? The calculated result is that the benevolent sees benevolence, and the wise sees wisdom. However, for a building automation system, the advantages of using carbon dioxide sensors are mainly reflected in the following three points:

1.Carbon dioxide sensor improves living environment and makes people feel more comfortable

Even if they don’t know the role of the carbon dioxide sensor, people still prefer to live in a more comfortable place, hoping that a better environment will bring a more comfortable business space. A good indoor air atmosphere can bring greater efficiency. Good ventilation is more likely to emit harmful gases, eliminating the risk of unhealthy factors that can lead to acute illnesses, such as asthma, asbestos, cancer, and more.

2.Carbon dioxide sensor reduces energy consumption

Just like by controlling the temperature and humidity at each point and lighting according to the actual demand, by controlling the carbon dioxide content to control the exchange of fresh air, the operating cost is minimized when the environment maintains the best comfort level. In this way, the consumption of global environmental energy and the increased global greenhouse effect will be slowed down and reduced together. Moreover, according to the “Kyoto Protocol” in 1997, the country is now working hard to reduce the greenhouse effect and promote green and energy-saving housing.

3.lower maintenance costs

In the management of smart buildings, by monitoring the entire system components, building managers can design and perform maintenance in a more efficient manner, and the actual maintenance situation is mainly based on the actual needs of the maintenance rather than a predetermined schedule. Before anything goes wrong, analysis of performance degradation and other signs of possible damage can provide the necessary actions to take to prevent it. This allows normal business hours repairs to replace the additional damage from expensive emergency repairs.

With the increasing improvement of people’s living standards, the further reduction of the cost of carbon dioxide sensors, and the deepening of the concept of green energy saving, carbon dioxide sensors will be more widely used in green and environmentally friendly buildings and homes, and can better reflect the advantages. It will bring people a better, more environmentally friendly and more energy-saving green life.
