Description

The HS-S02-L operates on the principle of modulated infrared reflection. It emits a 38kHz IR beam and detects the reflected signal from an object, converting the received intensity into a corresponding analog voltage or a clean digital on/off signal. This design provides reliable proximity detection for automated systems.

Engineered for stable performance, the module includes onboard signal conditioning circuitry for noise immunity. Its operating temperature range of -10°C to +60°C ensures reliable functionality in various indoor and controlled industrial environments.

Key Features

  • Dual-output interface provides both TTL-level digital and 0-Vcc analog signals.
  • Broad voltage compatibility supports direct connection to 3.3V and 5V microcontrollers.
  • Optimized 38kHz modulation frequency minimizes interference from ambient light.
  • Low quiescent current (≤2.0 mA) enables use in battery-powered applications.
  • Compact, single-board design with pre-mounted IR LED and phototransistor pair.
  • PH2.0 3-pin connector offers a secure, solderless connection for rapid prototyping.

Applications

  • Mobile robot and AGV (Automated Guided Vehicle) front collision avoidance.
  • Proximity sensing for automated doors, gates, and conveyor belt safety systems.
  • Object detection in DIY electronics, interactive art installations, and smart toys.
  • Line-following robot auxiliary sensor for detecting intersections or blockages.
  • Simple presence detection for inventory counting or item-on-belt verification.

Frequently Asked Questions

What is the operating voltage range for the HS-S02-L sensor?

The HS-S02-L operates from 3.3V to 5.5V DC, making it directly compatible with both 3.3V logic devices like Raspberry Pi and ESP32, and 5V systems like most Arduino boards. Ensure your power supply provides a stable voltage within this range.

How do I connect and use the digital (D) and analog (A) outputs?

The digital (D) pin provides a TTL-level high/low signal when an object is detected within a preset threshold distance. The analog (A) pin outputs a variable voltage proportional to the reflected IR intensity, allowing you to measure relative distance. Connect the D pin to a digital input and the A pin to an ADC input on your microcontroller.

What is the purpose of the 38kHz frequency specification?

The 38kHz modulation frequency is the rate at which the IR LED is pulsed. This allows the receiver circuit to filter out constant ambient infrared light (like from sunlight or incandescent bulbs), significantly improving the sensor's reliability and noise immunity in varying lighting conditions.
