Sensor
At its core, a sensor performs , which is the conversion of one form of energy (physical) into another (usually electrical).
: The sensing element interacts with the environment (e.g., a thermistor changing resistance as it heats up). sensor
: 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 At its core, a sensor performs , which
