Sensor [DIRECT]

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

: The internal circuitry translates this change into a readable signal. 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 : Detects motion by measuring changes in infrared radiation

: Measures distance by bouncing sound waves off objects. Use these for robot obstacle avoidance or liquid level monitoring. 2. Environmental converting physical phenomena—like heat

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