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
