This high-performance all-in-one gas sensing module combines a powerful microprocessor with a precision ADC to deliver accurate and stable gas concentration monitoring. Integrating four gas sensors onto a single board, it enables simultaneous detection of four different gases with unified output, solving long-standing issues such as incompatible interfaces, complex calibration, and limited sensor interchangeability. The module comes factory-calibrated and ready to use — no secondary development or re-calibration required. Simply plug in to start real-time data transmission and monitoring.Ideal for portable or fixed gas detectors, industrial safety systems, and other smart sensing applications, this module simplifies system development and accelerates your path to modular, intelligent gas detection.
