Gas Sensor Module vs Traditional Gas Sensor

What is a gas sensor module? What is the difference between it and a traditional gas sensor?

A gas sensor is a sensor device that detects the presence of a specific gas within a certain range or continuously measures the gas composition. Using gas sensors to monitor pollution in industrial and living environments is a very traditional and common monitoring method.

A gas sensor module is a sensor that has been redeveloped and has a signal output. It can also be simply understood as an “upgraded version of a gas sensor”. Sino-Inst will explain in detail what the difference is between a gas sensor module and a traditional sensor.

Gas sensor module

A gas sensor module is a sensor that has been redeveloped and has a signal output. It can directly output voltage signals such as 0.4-2V, 0-1.6V, 0-4V, and 0-5V. Serial port signals are also reserved.

It is the smallest and most powerful product on the market. Due to its excellent performance and reliability, it is widely used in scientific research, gas monitoring and other fields.

Traditional gas sensor

The traditional gas sensor is a converter that converts the volume fraction of a certain gas into a corresponding electrical signal. The function is relatively simple and cannot be used in some fields with high-precision algorithms.

Its pins are generally divided into 3 pins and 2 pins. The 3 pin is the most commonly used.

Sino-Inst’s 800 series gas sensor module is a standardized, modular, and intelligent gas detection product. It is mainly designed to solve the problems of a wide variety of gas detection, incompatibility of gas sensors of different brands, complex production calibration, and limited replacement of core components.

With our 800 series gas sensor module, you only need to connect once in the early stage to quickly respond to customers’ detection needs for different gases. With dual outputs of analog voltage and digital signals, customers can collect data directly by powering. It is ready to use, without secondary development or calibration with standard gas. It can greatly reduce the company’s R&D and time costs, and quickly improve the detection accuracy and stability to a first-class level.
