何谓传感器（Sensor）？

传感器（Sensor）是负责将信息转换为可处理信号的元件或装置。
人类行为模式基于视觉、听觉、嗅觉和触觉感知信息而展开，在类似的人类行为模式下, 设备也会依据自身的传感器获取到的信息来进行控制或处理。
这些传感器收集并转换出如温度, 光, 颜色等物理量。
这些技术主要依赖半导体物质的变化特性, 此外, 利用酶与微生物等生物物质所构建的生物传感器也得到了广泛应用。

IoT与传感器
The Internet of Things (IoT) refers to various devices and systems connected to the internet. This includes not only smartphones, personal computers, and other communication devices but also medical equipment, wearable devices, vehicles, natural environments, and infrastructure. By enabling these devices to share information, IoT aims to enhance daily life, improve safety, and
