Description

The HS-S11-L gas detection sensor module is designed for integration into air quality monitoring and safety systems. It utilizes a semiconductor gas sensing element that changes resistance in the presence of target gases, providing a corresponding analog voltage signal. The onboard comparator also provides a clean digital output that toggles when a preset concentration threshold is exceeded.

Built on a durable FR4 PCB, the module is engineered for stable performance in indoor environmental conditions. Its low power consumption (≤20mA) and wide voltage compatibility make it suitable for battery-powered or microcontroller-based projects requiring gas leak detection or ambient air quality assessment.

Key Features

  • Dual Output Interface: Provides both analog (A) for concentration measurement and digital (D) for threshold alarm functionality.
  • Wide Voltage Compatibility: Operates from 3.3V to 5.5V, making it directly compatible with 3.3V logic systems and standard 5V Arduino boards.
  • Fast Response Sensing: Delivers a rapid sensor response time of ≤100ms for timely detection and system alerts.
  • Compact & Integrated Design: Features a small footprint (23x33mm) with all necessary signal conditioning circuitry on a single FR4 PCB.
  • Simplified Connection: Utilizes a standard PH2.0 2/3P terminal block for reliable and tool-free wiring.
  • Low Power Operation: Consumes ≤20mA during active sensing, suitable for continuous monitoring applications.

Applications

  • Indoor air quality (IAQ) monitoring systems for homes and offices.
  • Gas leak detection and early warning systems in workshops or kitchens.
  • Portable environmental data loggers and DIY safety devices.
  • Educational projects for demonstrating gas sensing principles with microcontrollers.
  • Integration into smart home automation for ventilation control based on air quality.

Frequently Asked Questions

What is the operating voltage range for the HS-S11-L sensor module?

The HS-S11-L module is designed to operate from a wide DC voltage range of 3.3V to 5.5V. This makes it directly compatible with both 3.3V logic systems like ESP32 or Raspberry Pi and standard 5V Arduino boards without requiring a level shifter.

How do I connect and use the analog and digital outputs?

The module provides separate pins for analog (A) and digital (D) output. Connect the analog pin to an ADC input on your microcontroller to read concentration levels as a voltage. The digital pin provides a high/low signal based on a preset threshold, useful for triggering an alarm or relay without analog processing.

What type of connector does the HS-S11-L module use?

It features a PH2.0 pitch 2-pin or 3-pin terminal block for power and signal connections. The 'V' pin is for positive supply (3.3-5.5V), 'G' is ground, and 'A'/'D' are the output pins. This connector allows for secure, tool-free wiring with standard Jumper wires or dupont cables.
