Advancements in robotics have reduced human intervention in hazardous environments, leading to the frequent deployment of autonomous systems for security purposes. Fire accidents pose a common and ...

When the flame sensor detects a flame, the Arduino sends a signal to illuminate the red LED, indicating that the fire alarm has been triggered. The green LED (D2) is connected to another digital ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

今回は、Arduinoで超音波センサーを使って距離を測る方法についてご紹介します。 超音波センサーは触らずに物体との距離を測ることができます。 応用すれば、「物体が一定の距離まで来たら停止する」という動きをロボットにさせることもできます。

Fire safety alarms are crucial in both residential and industrial environments. Early fire detection can prevent significant damage and save lives. Flame sensors offer one of the most efficient ...
