  • News - Enginursday - RFID techno… | about 7 months ago

    My favorite fun project was one where I took an ID-12 reader and a pair of XBee radios to make an auto-login system for my desktop computer. I put the ID-12 set to serial mode, and the XBees to be a wireless serial port under my desk chair seat. Then put my RFID card in my wallet. When I sat down, the system would transmit the ID to the desktop computer and if it was the correct ID, the computer would unlock. I later tweaked it to pick up the loss of “tag in range” signal from the reader to re-lock the system. Worked surprisingly well (while the batteries lasted.)

    I’ve had trouble as well. I’m just coming back to the site to try again, but so far haven’t been thrilled with the unit.

    Finally! Mote Engineer putty!

    Just a note - have this hooked up now and it’s working well. I have had a couple of bumps and scrapes (part of the learning process.) A couple of learnings to pass along - I’ve got it hooked to an XBee and was running it on 4 AA’s and it went under voltage in about 2 days (granted fairly hot weather.) The Battery reading still showed good on my last reading so I’m trying it with a 9V to see if I can do better power prediction. I also need to do a calibration - the two temp sensors are about 1.5 degrees F off from each other.
    I can say it works well with the XBee - using the bluetooth RF contacts and it’s quite happy.

    From the PDF documentation:
    The following is an example output of the “Simple” text option from the Weather Board:

    21.81,081.28,026.5,079.7,083534,918,0,000001$

    21.81,081.33,026.5,079.7,083527,919,0,000002$

    Every second a new set of readings is displayed. There are 8 cells of data separated by commas.
    Cell 1 (21.81) = 21.81% Humidity?
    Cell 2 (081.28) = 81.28F from the SHT15 sensor?
    Cell 3 (026.5) = 26.5C from the SCP1000 sensor?
    Cell 4 (79.70) = 79.7F from the SCP1000 sensor?
    Cell 5 (083534) = 83854 Pascal from the SCP1000 sensor?
    Cell 6 (918) = a relative reading from the TEMT6000 light ? sensor (pretty dark)
    Cell 7 (0) = battery level is 0 (no battery attached)?
    Cell 8 (000001) is record number and will increment ? each second

No public wish lists :(
