Product Introduction
UK Alphasense CH-A3 Catalytic Combustion Methane Sensor Module (CH4)AG-3-LEL-CHA3 （D）Description:
The AG-3-LEL-CHA3 sensor module consists of a catalytic combustion sensor and a data acquisition processing board, capable of detecting concentrations of flammable gases such as CH4, C3H8, H2 in the environment. The module uses Alphasense CH-A3 catalytic combustion sensor as the sensing element, and detects gas concentration under the control of the sampling circuit, with good stability and anti-poisoning performance. This module communicates digitally with the receiving terminal, outputting gas concentration signals via the UART bus, making it convenient for users to quickly form a system in a simple way in different occasions, suitable for gas detection in industrial fields.
