Product Specification

Equipped with KE-25LF Battery lead-free oxygen sensor module (O2) AG-4-O2-MKE25 Product Description：

The AG-4-O2-MKE25 is an embedded type module equipped with the Figaro’s Oxygen Sensor KE25, for accurately detecting Oxygen (O2) gas concentrations in various environments. The module has been pre-calibrated before leaving the factory and has good stability and selectivity. It uses digital communication (UART bus output) for gas concentration, which allows users to easily and quickly integrate the module into various systems, making it suitable for both indoor and outdoor air quality detection, as well as industrial gas detection.
