Data Loggers

Onsite Weather Logger/Propeller
The OWL3pro is a data logger, capable of various and sundry tasks. It is based around the Parallax P8X32 Propeller, a 32 bit, 8 core microcontroller capable of running multiple routines in parallel. sensor, communication, and data processing.

OWL Data Logger
The OWL2pe is a data logger built around Parallax's BASIC Stamp. It includes digital and analog i/o, a battery backed real time clock, 512k memory, and many other powerful features. The OWL2pe can be used either on its own or as the core module to plug into a larger terminal board.
