Automated Weather Station – revisited

[today: rest day, yesterday: 3.4 miles]

We are starting to get some heat around here recently!

A few weeks ago the weather station in Starkville quit working.  So last weekend I stopped by and collected the equipment to bring home and see what’s up.

A recap:  I purchased three weather station devices off of the GSA auction site.  They are nice units from Vaisala, usually cost a few thousand $$ each.

I built two weather stations.  The first was this one in Starkville and the second as at my house here in Columbus.   I sold the last weather unit to help fund the overall project.

I used a beaglebone single-board-computer (SBC) which runs a flavor of linux, and the wview software.  Wview is able to talk to the Vaisala weather equipment.  The station in Starkville used the beaglebone-white, an earlier version SBC which runs off of a mini-SD memory card.  The Columbus station uses a later beaglebone-black which has static internal memory.

The problem with the SD card as a fake disk drive is that SD cards wear out.  After a year of 24×7 operation the Starkville station doesn’t want to boot up any more.

So I have acquired another beaglebone-black and I’m going to get the thing configured and running again.

I had a bit of  a scare with the weather station gizmo.  When removed from the installation the bottom of the thing was full of ants, ant eggs and junk.  I took it apart and brushed and blew it out with some compressed air.  Then I tried to get the station to talk to me and had a real struggle.  I stripped down the hardware completely, thinking that maybe the ants had messed up the circuit boards.  But other than dirty there’s no problem there.   For awhile I was sure it was dead. Finally I read the instruction book and got the thing to talk to me.

Now I have the new beaglebone-black talking to the weather station.  That means the serial port hardware is configured and working.  I have Wifi working, but it needs some more attention to make sure it comes up on reboot.  And then I need to build apache, php and wview.
