![circuitikz 中的 PIR 传感器组件](https://linux22.com/image/363143/circuitikz%20%E4%B8%AD%E7%9A%84%20PIR%20%E4%BC%A0%E6%84%9F%E5%99%A8%E7%BB%84%E4%BB%B6.png)
请问,我想在我的 circuitikz 图纸中添加一个 PIR(运动)传感器。我在官方手册或互联网上找不到任何东西,有什么想法吗?
答案1
以下代码定义了一个新的 circuitikz 形状以及一些有用的锚点。参数pir/height
、pir/pitch
和pir/width
允许pir/radius
更改新形状的大小。
