In-Cave Data Logger Project
Sponsored by the Central Connecticut Grotto

To develop a data logger to log caver traffic and environmental conditions in caves.

This project is a work in progress, is frequently updated, and done entirely by volunteers. For more information, updates, and other documents, please contact us. We encourage the sharing of cave data logging technology.

Mini Status Update - July 2011:
We are moving along, not as fast as desired, but moving. As technology improves, we are using a more efficient microcontroller, using multiple sensors, and phasing out the RS-232 interface in favor of a USB interface. If you would like to be notified of significant project updates, please contact us (see above).
