Gas Sensor Board (#27983) - RS Components

This output also connects to a red LED on the Gas Sensor Board. The zero gas span adjustment is set via potentiometer R3. As mentioned above R3 allows you to change the span/range of the voltage divider formed by the gas sensor and R3 which is the bottom leg of the divider, electrically speaking. Adjusting R3 to lower values will make the gas sensor less sensitive but more stable. Avoid ...

Adafruit SGP30 TVOC/eCO2 Gas Sensor

· All VOC/gas sensors use the same underlying technology: a tin oxide element that, when exposed to organic compounds, changes resistance. The 'problem' with these sensors is that the baseline changes, often with humidity, temperature, and other non-gas-related-events. To keep the values coming out reasonable, you'll need to calibrate the sensor. If no stored baseline is available …
