Design Micro and Firmware run on it

Basically we want a board that has four or five sensor inputs on it It will need a phosphine (ph3) sensor Carbon Monoxide Flammable gasses, smoke Temperature and a humidity ammonia sensor hydrogen chloride And a case tamper switch Plus two more analogue inputs for additional growth It will need a small lith batt to support itself for 8 hrs(or so) if the pwr goes off Now that’s all pretty easy, we then need a POE (correct POE) and RJ45 with with IP (DHCP or static and router) and a GSM port that can use and use a private APN We would prefer it in a in a less that 100mm round form factor board but size is not the main concern we want full electronics and software, prototypes ready for manufacturer, long term project so want long term We are still finalizing to protocols but config from tftp using its IMEI as file name i presume , and upload data like “StartIDtermIDTimeIDSencor1,2,3,4,5,… ENDID” or STARTID TermALarmIDsensorreading” by telneting to a socket and handshake then data we have more detailed spec if we want to talk more we have been ripped on by a guy on this site so are careful now
