Introduction: 4 Channel K-type Thermometer Using Arduino

Hi, this is simple made 4 Channel Thermometer- Data logger using Arduino.
I made this project for research work (measuring temperature gradient in agar phantom loaded with magnetic nanoparticles) of a PhD student in Material Science Lab. So, you can also make this project and sell it professionally.

This system can;

> Record temperature of each thermocouple

> Recording/ data-logging interval is 4 sec.

> Write data on Sd card.

> Data is in excel sheet to plot the graph

> It will ask to delete file using button

Step 1: Schematics
