🔍 What Is an Infrared Sensor System and How Does It Work?
Infrared (IR) sensing works by detecting heat radiation or reflected infrared light emitted or bounced back from objects and people. Because the human body naturally emits infrared energy, IR sensors excel at motion detection and presence awareness.
⭐ Key characteristics of infrared systems:
- ✔ Passive or active sensing modes
- ✔ Line-of-sight detection
- ✔ Cost-effective hardware
- ✔ Simple software integration
➡ As a result, infrared sensors are widely used by interactive game manufacturers, digital art installations, and smart lighting companies.
📡 What Is Radar Interaction and Why Is It Considered Advanced?
- ✔ Works through smoke, fog, or obstacles
- ✔ Detects motion in complete darkness
- ✔ Offers depth, velocity, and trajectory data
- ✔ Highly stable in complex environments
Therefore, radar is increasingly adopted by latest smart buildings, industrial automation, and high-end interactive entertainment manufacturers.
