An innovative solution able to provide real-time gas leak maps for gas network and industrial sites will be presented. This solution is being developed in collaboration by eLichens (a gas sensor leader), CEA LETI (a world-wide level research institute) and GRDF (the French gas distributor leader) and its ambition is to develop:

• A low cost 10-ppm sensor for CH4 detection
• A connected station that includes this sensor and allows remote monitoring of gas leak through a web interface
• A gas leak map computed from a network of connected stations deployed on an industrial site.

This solution will be low cost, easy to deploy and will provide real time monitoring. It will detect gas leaks in real time either continuous or temporary (related to some process or conditions).
