HS-S02A Infrared Obstacle Avoidance Sensor Module - Digital & Analog Output
The HS-S02A is a compact infrared obstacle avoidance sensor module compatible with 3.3V and 5V logic systems like Arduino, Raspberry Pi, and ESP32. It provides both digital and analog output signals for flexible integration into robotics, automation, and proximity detection applications.
Features
- Dual digital (D) and analog (A) output signals for versatile interfacing.
- Wide 3.3V to 5.5V operating voltage range for compatibility with 3.3V/5V MCUs.
- Standard 2.54mm pin header for easy breadboard and prototype board integration.
- Compact 45mm x 31mm x 18mm footprint with pre-drilled 3mm mounting holes.
- 38kHz modulated IR signal for improved ambient light immunity and reliable detection.

The HS-S02A infrared sensor module utilizes an infrared LED emitter and a phototransistor receiver pair. It operates on a 38kHz modulated signal to minimize interference from ambient light sources, providing reliable obstacle detection. The module outputs both a digital signal (high/low) for simple threshold-based detection and an analog voltage proportional to the reflected IR intensity for distance estimation.
Designed for embedded systems and DIY electronics, its standard 2.54mm pin spacing and clearly labeled pins (GND, VCC, Digital Out, Analog Out) simplify wiring. The module’s compact size and integrated mounting holes allow for secure installation in robotics, automated guided vehicles (AGVs), and interactive installations.
