MATLAB Arduino Tutorial 15 - Visualizing Geotagged (GPS) Temperature Data

This video demonstrates how to visualize GPS tagged TI TMP 102 Temperature Sensor data using the Arduino UNO board and MATLAB. The UNO board logs real-time latitude and longitude data using the USGlobalSat EM-406A GPS Module along with the time-stamps. This data is then acquired by MATLAB and displayed on the command window.

Configuration:
- Matlab R2012a
- Arduino 1.0.1
- USB 2.0
- USGlobalSat EM-406A GPS Module
- TI TMP 102 temperature sensor

Your code for the convertDegreesToDecimal is wrong. NMEA strings are not formatted in dddmm.ss they are formatted in dddmm.mm where the numbers after the decimal point are the fractional remains of the next minute. For example 4807.038, N means 48 degrees 07.038' North. Your code assumes that it means 48 degrees 07' 04''. Though this is a very small difference when it is converted to decimal degrees, it is still more accurate.


Also your code states that if the direction is EAST or WEST then the decimal number should be negative. This is incorrect as it should be SOUTH or WEST that makes the decimal number negative.

Hi.. I need to develop a GUI that can plot graph of real time temperature reading from Arduino Uno using serial communication. How can I make it? I do hope you can help me.
