当威利斯（Willis）载体设计一个风扇，管道和穿孔管系统时，该系统成为1902年（120年前）的第一个现代电动空调（AC）时，感应不是材料清单的一部分。
Devon Brock, Manager of Product Knowledge and Training, Sensors Group at TE Connectivity provides some insight into subsequent AC systems. He says, “Originally the control systems were quite crude and typically had more switches than sensors.” In fact, bi-metal temperature switches and pressure switches are still used to some extent.
“如今，更复杂的系统还需要更多的传感器和不同类型的传感器，除了压力和温度，” Brock说。“更多的传感器检查环境，但也有更多的传感器实际运行系统。”
除湿度外，CO的气体传感2contributes to environment sensing. In today’s heating, ventilation and air-conditioning (HVAC) systems, sensors play an integral role in helping to not only maintain a comfortable and safe indoor climate, but also to enable reduced downtime, improved productivity, lower maintenance and operating costs, as well as improved sustainability.

Increasing HVAC complexity and the resulting increased use of sensors occurs as the end use changes from a home (residential) to a commercial and, finally, enterprise-level systems. At the higher end, the HVAC system is more tightly integrated into the overall environment.
TE Connectivity的传感器组客户经理Paul Sittard指出：“建筑自动化系统非常复杂。”“你在看着一切。”
This includes sensing for vibration monitoring and more, similar to monitoring and maintenance in automated factories in the Industrial Internet of Things (IIoT).
According to the U.S. Energy Information Administration (EIA），“当包括电气系统的能源损失时，住宅和商业部门分别占2020年美国总能源消耗的约22％和18％。”
Part 2 will go into greater details in today’s HVAC sensors.
