Soldier Health And Position Tracking System Using Arduino,GSM Module and GPS Module.

Soldier Health And Position Tracking System Using Arduino,GSM Module and GPS Module.

The soldier Health and Position Tracking System allows military to track the current GPS position of soldier and also checks the health status including body temperature and heartbeats of soldier. The System also consists extra feature with the help of that soldier can ask for help manually or send a distress signal to military if he is in need. The GPS modem sends the latitude and longitude position with link pattern with the help of that military can track the current position of the soldier. The system is very helpful for getting health status information of soldier and providing them instant help.

Replace the XXXXXXXXXXXX with the recipient’s phone number.

Note: you must add the number according to the international phone number format. For example, in INDIA the number is preceded by +91XXXXXXXXX.

char phone_no[] = "+91XXXXXXXXXX"; //replace with phone no. to get sms
 Gsm.println("Alert I need help....Asheesh ,Battalion No. 1233456 ");
// Coutomize this text according to you.

  1. i try to replicate using button as trigger it sends the flat and flon but there is n comma separator so when i click the link its getting error loading the map, and “LOCAL” did’nt work

  2. When I send local from my phone the Gsm doesn’t send any msg to my phone..I have setted a Airtel 4g sim..what can I do now pls tell

  3. Hi sir!
    Can I have your whatsapp number ?
    Can I have the documentation of this project?
    I really need your whatsapp number.
    Please send me!
