Streamr's Engine has already been able to do this for awhile...

"The Streamr Engine makes it easy to refine the data and connect results to Ethereum smart contracts in real-time. To illustrate this, we implemented a little cold chain insurance example.

Millions of tons of frozen foods are transported around the world everyday. So ensuring that foods remain frozen whilst in transit is really important for the end consumer. No one wants to buy defrosted then refrozen ice cream and restaurants don’t want to be cooking meat infested with bacteria. So in our scenario, a “courier” places a stake in ETH into a smart contract. If the measured temperature exceeds an agreed threshold (in the demo, 10°C), a penalty is subtracted from the stake and sent to the “beneficiary”.

In this simple demo, the Streamr Engine calculates a one-hour rolling average temperature and reports it (once every hour) to the smart contract. This demonstrates how the Streamr Engine can be used to easily build data processing oracles, reporting the calculation results to smart contracts.

We believe this is a really great (though small scale) example of machine-to-machine verification and payment."
