The MMD1008 methane gas sensor module is a miniature gas sensor module developed based on MEMS methane gas sensor. It can be used to detect hydrogen gas level in air and send out alarm signals. This module has Anti-interference to common organic gas such as alcohol.
It is suitable for smart kitchen appliances (gas water heaters, gas stoves, etc.), gas detection, fire safety, portable detectors, etc.
