Hello all,

This project uses BasicStamp 2P (also you can use PIC) to interface with a DS1307, SHT15, JP Module and 16x4 LCD display. Code used is standard PBasic 2.5, it should work on most BasicStamp chips.

The project is a data logger demonstration program. It can record temperature and humidity data to MMC/SD card with date and time. Press the temperature unit select button switch to select Celsius or Fahrenheit. The data can be processed to the virtual XY chart or Polar Chart through the website ( www.jianpingusa.com/jpchart ).
