Open Source Environmental Data Logger

Submitted by edwbaker on Thu, 2014-05-29 12:46

Open Source Environmental Data Logger in use at the Natural History Museum,London.

Introduction

This project is part of the Open Source Data Loggers project.

Proprietary data loggers can be expensive - for example a three channel data logging system is available from Alphatemp for £465.00. Such costs make large scale deployment of such systems unfordable for all but well funded projects. This project aims to create an open source and open hardware data loggers making use of the widely avaialbale Arduino prototyping platform.
