: Detects motion by measuring changes in infrared radiation. Ideal for security lights or alarms.

At its core, a sensor performs , which is the conversion of one form of energy (physical) into another (usually electrical). sensor

: The sensing element interacts with the environment (e.g., a thermistor changing resistance as it heats up). : Detects motion by measuring changes in infrared radiation

: 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 : The sensing element interacts with the environment (e

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
