The small size tracking system make use of an node mcu esp8266 module as the micro controller, OLED display, NEO 6M GPS module, push button, SIM800L GSM module and a power supply set-up.
Project working principle
The GPS module receives location coordinate anytime it is connected to GPS satellite, that coordinate received can be viewed on google map to know the location of the GPS module. That location will be sent in two ways, a push button is added to send location in form of a SMS in case of emergency to an assigned mobile phone number through the GSM module, the location will also be sent as an SMS to an assign mobile phone number every 30mins so as to keep track of location.
