The LPG Click board utilizes a tin dioxide (SnO2) semiconductor sensing element. In clean air, the sensor’s conductivity is low. When LPG is present, the gas interacts with the sensing surface, causing a measurable increase in conductivity proportional to the gas concentration. This change is converted into an analog voltage signal for processing by a host microcontroller.
The module requires a preheating period for the sensor element to reach optimal operating temperature and stable baseline readings, typically up to 24 hours after initial power-up. The onboard potentiometer allows fine-tuning of the load resistance to calibrate the sensor’s response for specific environmental conditions or alarm thresholds, ensuring reliable performance in safety-critical monitoring applications.
