Arduino Proximity Sensors - Precision & Reliability

Ultrasonic Sensors: Use sound waves (typically 40 kHz) to detect objects; effective range from 2 cm to over 10 meters, depending on model and environmental conditions.
Infrared (IR) Sensors: Rely on infrared light reflection; shorter range (2 cm to 30 cm), ideal for obstacle avoidance in robotics.
Capacitive Sensors: Detect changes in capacitance; suitable for proximity or level sensing, even through non-metallic materials.
Inductive Sensors: Detect metallic objects only, with ranges typically under 50 mm, commonly used in industrial machinery.
