Methane gas sensorPrecautions

1. This product uses the brand's original semiconductor methane module, which requires a certain amount of preheating time for the first power on. After preheating for ten minutes, it can basically work normally, but generally the data is considered stable after 24 hours of preheating.

2. Sensors should avoid exposure to silicone adhesives, hair gel, silicone rubber, putty, or other places where volatile silicone compounds are present. If the surface of the sensor adsorbs silicon compound vapor, the sensitive material of the sensor will be enveloped by silicon dioxide formed by the decomposition of silicon compounds, which suppresses the sensitivity of the sensor and is irreversible. Do not use the sensor for a long time in environments with high dust density.
