Hi, I am working on a project.
I need up to a hundred sensors reporting the voltage to a computer or a website.
Each sensor must send its personal ID and the voltage once an hour.
This data must be sendt wirelessly. Wifi or radio.
The reciver must send the data to a computer or a website.
I am looking for DIY project or ready components.

Any thoughts on how this might be done?

Any help and tips is much appreciated. Thanks!
 

Sub-GHz FM radio modules are best suited, 433, 868 or 915 MHz band depending on your region. Ready-made modules are available from many vendors.
 

It might be best to start looking for a suitable (battery powered ?) data logger that can handle all of your required inputs.

It very likely will have a serial data output that can be fed by cable to a PC or modem. That serial data could then go through a radio link as suggested by the previous poster.

Its really a case of seeking out suitable compatible commercial equipment within your budget, that should pretty much just all plug together.
