Product Specification

Equipped with seven series electrochemical gas sensor module (CO, H2S, NO2) AG-4-GSB-MA7S Product Description：
The AG-4-GSB-MA7S is an embedded type module equipped with the Alphasense 7 series electrochemical Sensor, capable of detecting various toxic gases such as CO, H2S, and NO2 in diverse environments. The module has been pre-calibrated before leaving the factory and has good stability and selectivity. It includes a built-in temperature sensor for data correction via software algorithms to minimize environmental impact on measurement accuracy. It utilizes digital communication through a UART bus output for gas concentration readings, which allows users to easily and quickly integrate the module into various systems. The module is suitable for both indoor and outdoor air quality monitoring, as well as gas detection in industrial applications.

The module features an automatic short-circuiting of PINs when power is off with zero bias. For zero-bias sensors, the module operates stably after being powered on for 30 minutes. For sensors with bias, it is recommended to power on the module for more than 24 hours before use.
