What Are Specialty of M-4S Series Gas Sensor Module?
With lightweight, portable gas detection devices now in high demand, limited internal installation space has become a common challenge across the industry. Sangbay Sensor’s newly launched M-4S SERIES GAS SENSOR MODULE combines numerous advantages together—including a compact design, unified interface, factory calibration, standard protocols, and plug-and-play functionality, specifically designed for portable and miniature gas detection devices.
1 Compact Size, Ideal for Portable Devices
The M-4S series gas sensor module utilize small-volume sensors with dimensions of Ø20mm × 18mm (excluding copper pins) and a weight of approximately 10g, which makes it better suited for various portable detection instruments.
2 Factory-Calibrated for Precision
The module undergoes precise full-range calibration before leaving the factory and features standardized interfaces and packaging. Customers can directly acquire standard concentration signals for data transmission and online monitoring.
3 Full-range Temperature Compensation Algorithm
The M-4S series gas sensor module utilizes a high-performance microprocessor, features a high-precision analog-to-digital converter, and incorporates a built-in temperature sensor along with a precise full-range temperature compensation algorithm, enabling accurate detection of ambient gas concentrations even in varying temperature conditions.
4 Standard MODBUS Protocol for Simple Development and Integration
Using a standard UART (TTL 3.0V) communication interface, the modules support the standard MODBUS-RTU communication protocol with six selectable baud rates. Module addresses can be set independently, facilitating network deployment with multiple modules.
5. Supports Hot-Swapping While Powered On
The product supports hot-swapping while powered on, eliminating the need to power down the entire system, reducing operational complexity and minimizes downtime.
6 Compatible with Multiple Sensors, Flexible Selection
The M-4S series gas sensor module features a unified interface and packaging, making them compatible with gas sensors based on various principles—such as electrochemical and catalytic combustion—as well as covering a wide range of detection needs, including CO, H₂S, O₂, NO, NO₂, O₃, NH₃, H₂etc..
The M-4S series gas sensor module has undergone rigorous testing and validation across four major categories—electrical, functional, metrological, and environmental—totaling 20 tests. While reducing the overall size of the device, it fully retains all detection functions without compromising performance.
