Cloud Sensor -- First iteration
14 May 2016Since my last post, I've made a bit of progress:
I've ordered the Sunfounder Arduino starter kit, along with a Arduino Uno clone and a Mega clone (all arrived)
I've ordered the MLX90614 eval board plus a Redboard from Sparkfun (can't have too many Arduinos!) (arriving shortly)
I've done some initial playing around with the Arduinos and the accelerometer included in the Sunfounder kit, as a standin for the MLX90614. It amazes me how easy it is to get started with all of this...
I've grabbed one of the Raspberry Pis around the house and got it logging data over the USB serial port from the Arduino
Even got WiFi working on the Pi; it's an older one that doesn't have it built-in, but I've got an extra Asus N13 lying around that seems to work well
I've modified ttylog to include the date in its output; may not seem like much, but I'm no C programmer
Rough plan right now is:
Have the Arduino log once a second to the serial port; that's far too much data, but at least it'll be easy to see if it's working
Log that with ttylog; it'll be running under supervisor, and will log for an hour before exiting (and starting up again)
Once an hour, assuming WiFi works in its final location, try to rsync the log files home; if not working, pick up the log files manually
Put it all in a waterproof case of some sort, and find a place to plug it in at my in-laws (they've got a nice big yard)
