Putting together some methane monitors in the lab today using MQ-4 sensors, Arduino, and various compatible accessories. We will see if these can be good for monitoring at gas facilities! If anyone has experience with MQ-4 methane, advice welcome.

Our wonderful collaborator Mr. Tedy Mutisya Mwendwa is enjoying the challenge of designing such a monitor and doing a great job. Pictured below researching the design. Please excuse the messy lab space!

Outstanding work by Tedy building our prototype air sensor while in the lab the last two weeks. Clean Air Toolbox for Cities Godwin Opinde
