Details of work:
Create a small device with a GPS module and and 2G gsm module only to capture location information and send to an API(which I will provide).
1. Circuit diagram
2. Firmware code
3. Detailed Guidelines to burn the code on microcontroller
-- GSM and GPS and microcontroller must be certified modules and should be suitable for production use with minimum power consumption.
-- Overall size should not exceed 1"X1.2" with plastic casing.
-- GPS module accuracy should be up to 1-2 meters max.
-- There should not be any antenna coming out of the device.
-- Device should work inside the covered area with 0 sky visibility also.
-- There should be a LED blinking to identify if it is connected to GPS and GPRS.
-- Device should contain a USB rechargeable battery with 2 days backup.
-- FInal milestone payment will be made on successful testing of the device, which should take a week ideally after completion of the project.
