Suggestion of product

[PsySc0rpi0n]

Hello.
I'm new to LiLyGo products as the list is long.

I would like to have some suggestions of products, according to the following needs for my project.

1 - Need Wireless communication (to send data to a database)
2 - Need GSM/GPRS communication for the same purpose as 1, in case 1 fails due poor connectivity.
3 - Need GPS, for retrieving coordinates
4 - Need at least, about 24h of battery capacity or a connection to a solar cell to be able to charge the battery if possible
5 - If possible, no LCD to save in energy consumption

The project is to collect data from some sensors connected to this device and send the collectecd data to a central database.

This is a pilot project so it needs also the capability to scale up to multiple devices collecting data and send the data to the same database.

The devices will be on the street, so, the cheaper the better, in case they are stolen (I have some ideas to prevent this though).

I've been browsing the website but as the list is long I'm having some trouble to narrow down the list!

Thanks
Psy
