GSM / GPS Experimental Set

In GPS module, the GPS receiver decodes the NMEA data strings from the satellites and output to software interface for the discussion of current position, speed, direction, time, etc.

In GSM / GPRS module, the usage of AT commands is introduced. Students can use software interface to send AT command to control GSM / GPRS module, send SMS message and make a phone call through headset interface, or access to the Internet.
