Smart gas detector

132 views

Published on

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Low-cost smart sensor for detecting and warning about dangerous manhole/sewage gases.
