传感器在现代技术中得到广泛的应用,已经不是什么罕见和神秘的东西。但是以前的教材中对它很少关注,只是编入了一个很简单的分组实验:使用多用电表观察两种最简单的传感元件的电阻随温度或光照而变化的现象。对于传感器的应用,也仅用一个事例做了简单介绍。新课标高中物理对此? Sensors are widely used in modern technology, is not what the rare and mysterious thing. However, little attention was paid to it in previous textbooks. Instead, a very simple grouping experiment was put into place. Use a multi-meter to observe the phenomenon that the resistance of the two simplest sensing elements varies with temperature or light. The application of the sensor, but also only one case made a brief introduction. New curriculum standard high school physics this?
