I have a good project in mind that I want to collect around (12 analog & 2 digital) inputs, and send them to fleet management platform (like wialon) through gps device of course.
Now my questions are:
1- Is there a GPS device model that have up to 12 analog inputs? Or I should use an external adaptor (like arduino kit) to collect all needed analog/digital data and prepare them in one packet each time data will be sent??
2- If using external adaptor, how those packets (say every 5 seconds) should be sent through the GPS device?? Through its serial RS-232 port for example?!
3- Suppose complete data (around 15 sensors/data inputs) were sent every 5 seconds, can I see them all at units monitoring window when I place the mouse on the unit??
4- What is the perfect solution to achieve this goal (of monitoring more than 3000 units, each with 15 sensors) live online in one dash-board? No problem to divide the total number of units into groups of course..
Many thanks for your help.
