I need some help for a little Project.
The idea is that I have three Raspberry Pi devices. Each one is connected to an temperature sensor.
I want to create an autonomous system in which these objects can communicate through the Ethereum Network and send data to a fourth Raspberry.
I want do store the data Transaction in the Chain an the temperature too. So I will have the Chance to get the data in the Chain and on my Server Raspberry.
Is this possible?
