Our approach was to tackle this issue head on, building a very early prototype and using a minimum \u201cdata gathering platform\u201d around it to understand the pitfalls &amp; performance issues.<\/p>\n<p>This early work cut across several disciplines:<\/p>\n<ol>\n<li>Electronics, designing a custom circuit to best interface with affordable gas sensors<\/li>\n<li>Firmware, building on a development platform to gather and share sensor data over wireless<\/li>\n<li>Mobile app, customised to gather the local sensor data &amp; upload it to a data store<\/li>\n<li>Mobile backend, a real time database to capture the data streams and tools to help explore the data<\/li>\n<li>Mechanics, how to wrap this early prototype for real world use<\/li>\n<li>Early system testing &amp; validation approach<\/li>\n<\/ol>\n<p>We will be adding a few blogs to the site to cover progress on the above items; suffice to say the first mechanical housing for the unit followed the \u201cbreakfast cereal box\u201d approach.
