: The internal circuitry translates this change into a readable signal.
: The data is sent to a controller (like an Arduino or Raspberry Pi) via an analog voltage or digital protocol. 📡 Common Types of Sensors 1. Motion and Proximity sensor
Sensors act as the "eyes and ears" of electronic systems, converting physical phenomena—like heat, light, or movement—into measurable signals. This guide covers how they work, the major types available, and how to choose the right one for your project. 🛠️ How Sensors Work : The internal circuitry translates this change into
