不過鑽完孔都未完事 ,因為不同的 sensor module 有不同的安裝方法 ,所以我亦備有不同長度的 M3 / M2.5 / M2 的銅柱 。例如上面提到的 1602 LCD ( 帶 I2C backpack ) 和 PIR sensor,兩者都要撐起離地十幾 mm 來安裝的 ( 因為兩者原本的安裝方法是直接安裝在外殼裡面的 ,所以電路板背面的零件凸出得比...
Arduino Ultrasonic Sensor and LCD Display Example Example Code Using the NewPing Library Improving HC-SR04 Distance Sensor Accuracy with DHT22 Temperature Sensor Arduino code HC-SR04 Dimensions and 3D Model Conclusion I have already used the HC-SR04 ultrasonic sensor for building several cool Arduino ...
The main goal of this project is to design an Arduino based motion sensor light circuit which is used to detect the motion to turn on a light. The circuit of this project mainly built with the Arduino board, PIR sensor, LED, and USB with type a and b connector. When the motion is ...
The HC-SR501 is a Passive Infrared (PIR) motion sensor that is extremely useful. It can be used all by itself or combined with an Arduino or Raspberry Pi In this article you'll learn how a PIR sensor works and you'll build some cool projects using the HC-SR501. You can even make...

This is actually remarkably easy, a PIR sensor compares the infrared map of its environment with one it has built over time. So it detects changes. They can be found for $10 at several stores including sparkfun and robotshop These have everything integrated, and the output pin goes high fo...
