在这个简单的 DIY 项目中，我将向您展示如何设计和实现基于 PIR传感器的安全警报系统。我设计的这个电路使用 Arduino 作为主控制器，当然还有 PIR传感器本身。此外，我还使用了UM3561IC（警报器发生器IC），通过扬声器产生必要的警报声。 通常，在家庭、商店 ...

It’s been a while since the last top 10 article so I thought it would be nice to make another one for the last 5 months. What I’ve discovered is the fact that people are really enjoying the Arduino ...

Electrical power systems engineers need practical methods for predicting solar output power under varying environmental conditions of a single panel. By integrating an Arduino-based real-time data ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...
