Let’s first talk about the smart sensors used in smart building automation. The so-called intelligent sensor is a device that can sense environmental changes and transmit information after processing! In the field of building automation, it plays a very important role
Types of smart sensors
1. Temperature sensor : This thing can accurately sense the temperature in the building. For example, in large shopping malls, the air conditioning system can be adjusted through real-time monitoring of temperature sensors, so that the indoor temperature can be maintained in a comfortable range.
2. Humidity sensor : Can measure humidity in the air. In some places with high humidity requirements, such as museums, humidity sensors are needed to ensure the environment for the storage of exhibits.
3. Light sensor : can sense the light intensity. It is used in the office to automatically adjust indoor light according to external light, which can achieve energy-saving effects.
4. Sensor : Can detect whether there are people in a certain area. In the conference room, the lights are automatically turned off when no one is present, and the lights are automatically turned on when someone enters.
Advantages of smart sensors
1. Improve energy efficiency : By monitoring environmental parameters in real time, the building automation system can adjust the operation of equipment according to actual needs. For example, adjusting air conditioning and lighting according to temperature and lighting can greatly reduce energy consumption.
2. Enhance comfort : According to the information provided by the sensor, keep the indoor temperature, humidity, light and other conditions in a state where people feel comfortable.
3. Optimized maintenance : Sensors can monitor the operating status of the equipment, discover potential problems in advance, realize preventive maintenance, and reduce equipment failures and maintenance costs.
Installation and layout of smart sensors
The installation location of the sensor must be selected:
1. Height : For example, the temperature sensor is generally installed 1-2 meters above the ground, which can accurately reflect the temperature of the person's movement space.
2. Distribution : It should be evenly distributed in all areas that need to be monitored in the building to ensure the comprehensiveness of the data.
Q&A session
Q: Do smart sensors need to be calibrated regularly?
Answer: That's sure! Regular calibration can ensure the accuracy of sensor measurements, and it is generally recommended to calibrate once a year.
Q: Can smart sensors of different brands be compatible?
A: Some are OK, but some may have compatibility issues. When choosing, it is best to consult a professional to ensure that it can match the building automation system.
Q: How long does the service life of smart sensors last?
Answer: Generally speaking, under normal use, it can last 5-10 years, but the specific details depend on the use environment and maintenance status.
Comparing traditional sensors and smart sensors, traditional sensors can only measure simply, and smart sensors can also process and transmit information, which has much more powerful functions.
