S-M4 Gas Sensor Module-Shanghai Sangbay Sensor Technology Co., Ltd.

Product Overview

S-M4 intelligent gas sensor module is an integrated module that unified the interface of various gas sensors and converts them into digital signal output. It also has multiple modes including digital output and analog voltage output, making it convenient to use and calibrate. This module can be applied to gas detectors, industrial field gas detection, mine gas detection, atmospheric environment gas detection, and research institutions and universities etc.

Application Field

The module is standardized, with a unified interface and packaging for various types of gas sensors. It is precision-calibrated at the factory.
It is compatible with hot-swapping operation and can be connected with terminals for easy use without soldering.
It is precision-calibrated at the factory, so no further calibration is needed, and it is ready to use without additional development.
The output signal is diverse, supporting both digital (UART) and analog outputs, making it convenient to use.
The standard MODBUS communication protocol is supported.
It is compatible with various sensors such as infrared, electrochemical, and catalytic sensors.
It has a small size and light weight, with high accuracy, fast response, and strong stability.
The module has a short preheat time, low power consumption, and strong anti-interference ability.
