Product Overview

The K-5S series gas sensor module is a highly integrated sensor module with high performance and strong universality. The module uses a high-performance microprocessor, equipped with a high-precision analog-to-digital converter, an on-board temperature sensor, and accurate full-range temperature compensation algorithm, which can accurately detect the concentration of environmental gases. The module unifies the interfaces and packaging of various types of gas sensors, is accurately calibrated at the factory, and has both digital and analog voltage outputs for ease of use. It solves the problems of the variety of gas types, the incompatibility of sensor varieties, the complexity of production calibration, and the limitations of core component replacement. Customers can use it without secondary development or recalibration and can directly collect standard signals for data transmission and online monitoring.It is suitable for portable and fixed gas detectors and gas detection equipment, greatly reducing the complexity of gas detection equipment development and providing strong support for modular design of equipment.
