Product Overview

The TB600B series is an intelligent digital gas sensor module based on smart gas sensor technology and intelligent algorithm calculations. 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. This technology is based on the principle of electrochemical gas detection, 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 areas and other materials. The electrodes, electrolyte, and ambient air are in contact, and gases diffuse into the sensor's working electrode through the back of a porous membrane. On this electrode, the gases are oxidized or reduced, causing an electrical current to flow through the external circuit.
