Fairly self explanatory. Considering the Edison for a big project but it would need to perform the tasks:
1. Go to low power mode
2. Listen on a specific pin connected to an ultrasonic or PID sensor
3. Wakeup and do some wireless sniffing (return raw kismet/airodump/wireshark output) for x seconds
4. Back to sleep
Would this be possible to accomplish?

Hi kmuzumdar,
Some other user have been trying to accomplish this. I think you could take a look at this thread /thread/61067 https://communities.intel.com/thread/61067. CMata_Intel suggested that by using the lines below you can put the Edison into and out of standby mode.
echo -n "mem" > /sys/power/state
or
echo -n "freeze" > /sys/power/state
But some other users have reported that this works just once, so they have to reboot the board to make it work again. However, not so long ago someone post a link to a patch that makes the sleep mode more reliable than before. I would suggest you to try with that.
