1. Product Description

The single-channel gas sensor module series is a high-performance, versatile, and integrated sensor module. Equipped with a high-performance microprocessor and a high-precision analog-to-digital converter (ADC), the module can accurately detect environmental gas concentrations. 

The module standardizes the interface and packaging of various types of gas sensors. Each unit is precisely calibrated before delivery and features digital output for easy integration. It effectively addresses challenges such as the wide variety of gas types, incompatibility among different sensors, complex production calibration, and limitations in replacing core components. 

Users can deploy the module without secondary development or recalibration. Standard signals can be directly collected for data transmission and real-time monitoring. The series includes two models to accommodate sensors of different sizes. 

This module is suitable for portable and fixed gas detectors, as well as other gas monitoring devices. It significantly reduces the complexity of gas detection device development and strongly supports modular design in equipment manufacturing
