Winsen ZE03 Electrochemical H2 Gas Sensor Module


ZE03 is a general-purpose and high-performance electrochemical module. It uses three electrodes, an electrochemical gas sensor, and a high-performance microprocessor. By installing the different gas sensors, the module could detect relevant gas. It is with a built-in temperature sensor to make temperature compensation, which makes it could detect the gas concentration accurately.
