Building automation system is a central computer and a variety of control subsystems composed of a comprehensive system, which uses sensing technology, computers and modern communication technology, including heating, ventilation, elevators, air conditioning monitoring, water supply and drainage monitoring, distribution of power and power supply monitoring, automatic fire alarm and fire linkage, security and other systems to implement fully automated integrated management. Sensors are the primary equipment in the automatic control system, sensors are directly linked to the measured object. The role of the sensor is to feel the changes in the measured parameters, and send out signals that correspond to them. The current building automation system commonly used sensors are temperature sensors, pressure sensors, temperature and humidity sensors, liquid level sensors. 1, temperature sensors Temperature sensors used in building projects are mainly wall-mounted temperature sensors, waterproof temperature sensors, duct-type temperature sensors, etc., due to the temperature measurement element and the measured medium need to carry out a full heat exchange, the measurement is often accompanied by a lag in time. 2, pressure sensors Commonly used waterproof pressure sensors will be measured pressure changes converted to resistance, inductance and other changes in electrical quantities, thereby realizing the indirect measurement of pressure. Pressure sensors detect the pressure value or pressure condition of the space environment and working medium. 3、Humidity sensor Used to measure the relative humidity of indoor air. 4、Level Sensor Used to control the upper limit and lower limit level of water tanks and pools. Sensors in the building control system accounts for a small proportion of funds, but the status of sensors in the system can not be ignored, but also a very important link. So we are in the design of the sensor selection, the installation of sensors in the construction process should be very accurate in order to make our building control system to meet the expected requirements, so in the design stage of the project will need to carry out screening and negotiation of the sensor manufacturer by the sensor engineers and building automation system engineers together to choose the customized parameters to confirm the program and then construction can be guaranteed to be controlled by the electromechanical equipment is reasonable, safe to To ensure the reasonable and safe operation of the controlled mechanical and electrical equipment, so that the total energy consumption of the building is minimized.
