Description:
This advanced hydrogen sulfide (H₂S) gas sensor is engineered for precise and reliable environmental monitoring, offering versatile integration through three distinct output modes: analog voltage, I2C digital communication, and UART serial communication. Factory-calibrated for immediate deployment, the sensor delivers rapid and accurate H₂S concentration measurements, making it ideal for critical applications across industrial safety, subterranean monitoring, and environmental protection.
Leveraging the electrochemical sensing principle, this probe exhibits exceptional robustness against interference, ensuring high stability and sensitivity. Its extended operational lifespan of up to two years minimizes maintenance requirements. The sensor's sophisticated features include 32 user-configurable I2C addresses, an integrated temperature compensation algorithm to maintain accuracy across varying conditions, and a programmable threshold alarm function for real-time alerts.
Designed for seamless integration with popular microcontroller platforms such as Arduino, ESP32, and Raspberry Pi, the sensor employs a user-friendly Gravity interface. DFRobot provides comprehensive sample code, simplifying the development of custom H₂S detection systems.
This sensor is part of DFRobot's comprehensive series of 12 gas detection sensors, all utilizing a consistent data format and operational methodology. This series includes sensors for carbon monoxide (CO), oxygen (O₂), ammonia (NH₃), hydrogen sulfide (H₂S), nitrogen dioxide (NO₂), hydrogen chloride (HCl), hydrogen (H₂), phosphine (PH₃), sulfur dioxide (SO₂), ozone (O₃), chlorine (Cl₂), and hydrogen fluoride (HF). This uniformity allows for effortless combination and expansion of gas detection capabilities, catering to diverse monitoring needs.
