1. Product Description

The AG-2-CHX-M2618(D) sensor module consists of a semiconductor sensor and a data acquisition & processing board. Equipped with Figaro semiconductor sensor TGS2618-D, the module detects gas concentration under the control of its sampling circuit, featuring excellent durability and high stability. The module provides a USART output proportional to the detected gas concentration (a memory within the module stores factory pre-calibrated data). Additionally, the module can detect sensor open-circuit and short-circuit faults. It operates over a wide temperature range.

Furthermore, it exhibits low cross-sensitivity to organic gases and enhanced tolerance to silicon compounds, making it better suited for harsh environments. It is suitable for gas detection in both civil and industrial applications.
