Tips: How does the Methanol gas sensor work?

The Methanol (CH₃OH) gas sensor operates using the electrochemical three-electrode principle, where methanol gas undergoes an oxidation reaction at the working electrode, producing electrons and protons. This reaction generates an electrical current proportional to the methanol concentration, which is measured and converted into a readable output in PPM (parts per million). The sensor features a sensitivity of 200±100 nA/PPM and a response time of ≤30 seconds, ensuring fast and accurate detection. A reference electrode stabilizes the measurement, while the counter electrode completes the circuit.
