Data Logger “deLuxe”

The efficiency of simplicity

Published in issue 375, March 2008

Data Logger “deLuxe”
Elektor has a long history when it comes to publishing data acquisition systems and loggers — the most recent project [1] proved very popular. The data logger we are proposing here is unique due to its simplicity and compact size; a microcontroller and a handful of common components are all it takes for hardware. This data logger is used to save the values of four analogue channels supplying any voltage ranging from 0 to 5 V onto a standard memory card (SD – Secure Digital).

Update: February 2, 2008

New firmware in zip file -11 (free downlolad).

Change log:

- Fixed spelling bug "SYTEM STOPPED" to "SYSTEM STOPPED"

- Fixed junk character displayed after the last second digit on the time text line

 

Correction: Febuary 9, 2009

For proper level conversion between the USB and the PIC microcontroller, the schematic and the parts list should be corrected to read:

R5,R7,R9 = 2kohm2

R6,R8,R10 = 3kohm3

These changes have been implemented in the Component List published on the project web page.
