Sensor Selection and Installation
In smart building electromechanical systems, the selection and installation of sensors are crucial for the efficient operation of the system. Sensor selection should be customized based on the functional requirements and environmental characteristics of the building, with high-precision sensors significantly improving data accuracy. In temperature-sensitive areas, high-precision temperature and humidity sensors can be selected.
Installing pressure and CO2 sensors in ventilation or air conditioning systems enables more precise control. The layout of sensors should fully consider the structural characteristics of the building to ensure coverage of key areas and reduce blind spots. Through optimized sensor layout design, the air conditioning system can achieve precise temperature control on each floor, greatly enhancing system response speed and energy efficiency[12].
4.2
Data Collection and Processing Technologies
The data collection and processing technologies in smart buildings are the foundation for the intelligent operation of the system. To ensure that the system can respond quickly and process data efficiently, a robust data collection system needs to be established. This system should have multi-channel parallel collection capabilities while acquiring multi-dimensional environmental information such as temperature, humidity, pressure, and air quality. The advantage of this parallel mechanism lies in its ability to improve the speed and comprehensiveness of data collection, laying a solid foundation for subsequent data processing[13].
During the data processing phase, to ensure the accuracy and stability of the raw data, preprocessing techniques such as filtering and denoising are employed to clean the data. These techniques can remove noise signals and enhance data reliability[13]. Furthermore, intelligent algorithms (such as decision tree-based and neural network models) are used to analyze the sensor data stream, identify equipment operation anomalies, and predict future environmental trends. The formula for the decision tree-based model is

Selecting appropriate wireless communication technologies is crucial for the specific needs of smart buildings.
Technologies such as Wi-Fi, Bluetooth, ZigBee, and Long Range Radio (LoRa) each have their advantages and disadvantages, with ZigBee and LoRa being particularly suitable for large-area, low-power sensor networks due to their low power consumption, high reliability, and long transmission distances. When designing, factors such as transmission distance, data transmission rate, network load, device density, and system stability must be considered[14]. Optimizing communication protocols is also an important means to improve system efficiency. Utilizing multi-hop networks and distributed protocols can effectively reduce the burden on central nodes, enhancing system scalability and reliability. To ensure data security and real-time performance, suitable encryption technologies, anti-interference mechanisms, and redundancy designs should be selected.

5.2
Evaluation of Implementation Effects
From the field monitoring data, as the sensor layout density increases, data collection accuracy significantly improves, rising from 94% to 99%, indicating that the density of sensor placement directly affects the accuracy of data collection; the higher the layout density, the more accurate the collected environmental data. Network latency and data processing capabilities also improve with increased layout density, with network latency decreasing from 110ms to 80ms and data processing capabilities increasing from 160 to 170.
Although increasing layout density can optimize network transmission and data processing efficiency, the optimization effect gradually diminishes as the number of sensors increases. A reasonable layout density must find a balance between improving accuracy and controlling load, especially under high-density layouts, to ensure fast system response speed and high data accuracy.
