This is a Winsen ZE03-H2S 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. It has the digital output and analog voltage output at the same time which facilities the usage and calibration and shortens the development period. It is a combination of mature electrochemical detection principles and sophisticated circuit design, to meet customers’ different detection needs.
