Tags: Electrochemical O2 Oxygen Gas Sensor

The FS01500 is an electrochemical sensor designed to detect oxygen gas (O2). It operates using fuel cell technology, where oxidation and reduction reactions occur on the working electrode and counter electrode, generating a current proportional to the oxygen concentration according to Faraday's law. The FS01500 incorporates a high-stability gas sensor and a high-performance microprocessor, supporting UART output and Modbus-RS485 output for easy integration. The module utilizes precise automatic calibration and detection equipment to ensure data accuracy and consistency during large-scale production.
