i have a requirement for a code to be written for a system composed of a teensy 3.5, ESP8266 and multiple gas sensors.
the system would sample the air every 30 seconds and record the sensor readings on to the onboard microSD datalogger on the teensy3.5 board. at the same time it would send the sensor readings over wifi to my thingspeak channel, using the esp8266. there is potential in the future for notifications to be sent to a mobile device once a sensor reading threshold has been passed.
I appreciate that this may not be easy to describe/understand over email and may require a flow diagram and wiring schematic to make things clearer.
if this is something you think you would be interested in, it would be great to hear back from you and we could discuss the project in a bit more depth and i can get an idea of your rates and the length of time you would require for something like this.
