OctoPi is a Raspberry Pi version of octoprint. ( [login to view URL] ) I want to add a smoke detector and a relay to the Rasberry Pi. The plugin to OctoPi reads the level of air polution/smoke and set the threashold. When threashold is reached the relay goes open. Example of smoke sensor.

I've done a project with OctoPi customization before but I don't see any relationship between smoke detector and 3D printing (fyi... my previous project is adding the automatic resume printing when power outage & enable user to specify the Z level). Regarding to this project, my proposal is - instead of connecting the MQ8 sensor to the Raspberry PI, we will use the ESP8266 WiFi chip instead. The firmware on ESP8266 will be developed to read the output of MQ8 and if it exceed a predefined value, the relay will be turned on. With this solution, you just need ESP8266 ($3-$4), a relay with a transistor and resistor and of course the MQ8. You don't need the ADC module and the total size is very small. My bid does not cover the custom PCB design for the solution. This is also not include in my bid but if you want the OctoPi to get the relay ON/OFF information from ESP8266, we will add a web server inside esp8266 and octoPi will read the value via Rest API. Any question, pls let me know. Thanks, Anh

Hi. I have a Raspberry Pi 3 to test and develop with. I have suggested a length of 10 days, as 1) I would need to order components and wait for them to arrive; 2) it would take time to set up Octoprint to work with my own 3D printer (an early Reprap Prusa model). Let me know if you want me to investigate. I am based in Ireland.
