The METHANE Click utilizes a tin dioxide (SnO₂) semiconductor sensing element. In clean air, the sensor’s conductivity is low. When methane gas is present, the conductivity increases proportionally, generating a corresponding analog voltage signal. This board is designed for system-level integration, requiring a 24-hour preheat period after initial power-up for optimal sensor stability and accurate calibration.
The included potentiometer allows for environmental calibration by adjusting the sensor’s load resistance, tailoring the sensitivity to specific application conditions. The board’s design adheres to the mikroBUS standard, ensuring mechanical and electrical compatibility with hundreds of host boards from Mikroe and other manufacturers, simplifying prototyping and development.
