so, in search of a small, cheap mobile data logger, i came across the arduino-based logger (Mayfly by the Stroud Water Center engineers). At about $60 when available, this is a little pricier than normal arduino builds (Cave Pearl project, Adafruit logger shield + controller, Seeeduino Stalker- weird name) or roughly comparable (Sodaq MBilli). But with the hope of less soldering, real time clock with low drift, SDI-12 communications capability, LiPo single cell charge controller, and expandable/replaceable memory (via SD card), the specs were nice. Compared with Campbell CR300 price point ($600'ish) and unknown snow/enclosure crushing conditions, the Mayfly logger board becomes a good test platform for rugged conditions without destroying more robust logging platforms. And due to its size, it can be placed in a smaller enclosure higher up so it doesn't become quite the wind mast.
Attached is code for a Vaisala WXT 530 series weather station (user-defined composite SDI-12 message). This code, logger, and sensor ran about a week logging @ 5 min intervals in office conditions.
To be done: set up radio/cellular telemetry, but currently the site is a bit power-constrained.
