The Winsen ME4-NH3 ammonia gas sensor operates on the constant potential electrolysis principle. An oxidation-reduction reaction with ammonia gas occurs within the sensor’s electrochemical cell, generating a current directly proportional to the gas concentration. This linear analog output allows for straightforward interfacing with microcontrollers or data acquisition systems via a simple transimpedance amplifier circuit.
Engineered for reliability in demanding settings, the sensor exhibits excellent repeatability and stability with minimal cross-sensitivity to common interfering gases. Its robust design is suited for continuous monitoring applications where precise, low-level ammonia detection is critical for safety and process control.
