Product Specification

Semiconductor gas sensor detects LP propane with Figaro TGS 2619 AG-2-CH4-M2619(D) Product Description：

The AG-2-CH4-M2619(D) is an embedded type module equipped with the Figaro’s semiconductor Sensor TGS2619; the module has been pre-calibrated before leaving the factory and it includes a specialized filter that reduces interference from gases like alcohol, ensuring a selective response to methane (CH4). It utilizes digital communication through a USART and a programmable Alarm output interface for gas concentration readings. This allows users to easily and quickly integrate the module into residential gas leakage alarm systems, such as household natural gas detectors.
