在自动控制、信息处理技术中,担负着信息采集任务的传感器发挥着越来越重要的作用.目前,传感器已经广泛应用于生产、生活、科学研究的各个领域,如环境保护、交通运输、家庭生活、宇宙开发等,传感器技术已成为21世纪科学家在高新技术发展方向上争夺的一个制高点. 传感器是把非电学物理量(如位移、速度、压力、温度、湿度、流量、声强、光照度等)转换成易于测量、传输、处理的电学量(如电压、电流、电阻、电容等)的一种
In automatic control and information processing technologies, sensors that take on information collection tasks are playing an increasingly important role. At present, sensors have been widely used in various fields of production, life, and scientific research, such as environmental protection, transportation, and family. In life and space development, sensor technology has become a commanding point for scientists in the 21st century to compete in the direction of high-tech development. Sensors are non-electrical physical quantities (such as displacement, velocity, pressure, temperature, humidity, flow, sound intensity, illuminance, etc.) A type of electrical quantity (such as voltage, current, resistance, capacitance, etc.) that is converted into an easily measured, transmitted, or processed product.
