The MSD3005 gas sensor module can be used to detect dangerous gases (CO, hydrogen, and electrolyte) in the ambient environment, and provide alarms based on the concentration levels. The MSD3005 module is a small sensor array device. They use specific conditioning circuits and precise algorithms to determine the warning levels of three dangerous gases in the current environment.
