This 5 V IR proximity sensor module delivers precise, non-contact obstacle detection and tracking performance. Featuring an infrared LED emitter and photodiode receiver in a compact PCB module, it reliably detects objects in its path and outputs a digital trigger signal. Typical specification: supply voltage 4.5 – 5.5 V, detection range approx. 2 cm–30 cm, digital (HIGH/LOW) output, compact size for robotics, automation, smart toys and DIY electronics projects. Ideal for mobile robots, line-following cars, proximity alarms and industrial small-machine sensing
- High-performance infrared proximity detection – detects objects in 2 cm to ~30 cm range (depending on surface & ambient light).
- Easy two-wire interface – simply connect 5 V supply and digital output to your microcontroller (Arduino, Raspberry Pi, ESP32).
- Compact size and lightweight – easily mounts on robot chassis, smart car, conveyor systems or hobby electronics boards.
- Durable and noise-resistant – infrared sensing works reliably in variable lighting and for dark/reflective surfaces.
- Wide application scope – perfect for robotics obstacle avoidance, line tracking, automation alarms, smart home sensing.
- Simple integration – ideal for beginners and advanced hobbyists, supports plug-and-play with motor drivers and microcontroller boards.
- Low power consumption – efficient for battery-powered builds and portable systems.
