Product Overview

The TB600B series is an intelligent digital gas sensor module based on smart gas sensor technology and intelligent algorithm computation.

The TB600B gas sensor module is suitable for both indoor and outdoor industrial applications. It can detect gases, temperature, and humidity, and simultaneously receive all data.

Data is output via transmission commands, facilitating identification of the correct maintenance and replacement time.

Each sensor module is professionally calibrated with gas, and the calibration information is stored in a flash memory chip.

The sensor module features I2C or UART (TTL 3.3V) output interfaces, allowing for easy integration with various devices and systems.

Principle of Detection

Solid-state polymer electrochemical sensing technology represents an innovation in the field of electrochemical detection techniques.

The technology is based on electrochemical gas detection principles, measuring various gases that can be chemically decomposed.

The sensor consists of three electrodes in contact with the electrolyte, with typical electrodes being composed of noble metals with large surface area and other materials.

Electrodes, electrolytes, and surrounding air come into contact, with gases diffusing through the porous membrane to the working electrode of the sensor.

Gas is oxidized or reduced on this electrode, and this electrochemical reaction causes current to flow through the external circuit.
