OpenDLogger — Open Data Acquisition System

OpenDLogger

The OpenDLogger Project has been revised, and it is intended to form a flexible data acquisition module for multiple science & technology applications with moderate precision requirements and limited budget. It involves an open system in its hardware design and C source-code. The basic system is based on PWRC2 systems installed at the INTI-Neuquén test-site for small wind turbines since 2012, and on boards designed and produced through an ANR-SeCyT project (SC002/2003), which have been tested in different applications since 2005. We are aiming for a low power system with various analog channels, available ranges in 0–5 V or 0–10 V, using 10 and 13-bit A/D conversion.

The system has reduced power consumption. Features include:

SD memory storage, up to 2 GB using industrial grade SDs
Oriented to current, voltage and power measurements
Optional external METEO module for wind, temperature and barometric pressure measurements
Real time clock with Temperature-compensated crystal oscillator and CR3032 battery
Alphanumeric 4 × 20 LCD display
Membrane keyboard 4-key connector
Serial RS232 or USB module with FT232
Option: External line (220 VAC) power supply, connection to PV panel and external 12 V battery, working as mini-UPS
