unless it’s important you can look at past temperates you shouldn’t use a blockchain for this. Blockchains are good at getting a historical record and be sure it wasn’t tampered with. Anything else is wanting to use blockchain for the sake of using blockchain.
I’m doing something similar. With this particular sensor, it looks like you need a gateway device to receive the data. As @memario said, you should be using the blockchain to verify the integrity of the data. I would suggest the gateway device receiving readings from multiple sensors, and if they meet a threshhold, then a transaction could be made to the blockchain signifying the consensus from the different sensors.
If you really wanted to get fancy, look in to multi-signature transactions, and how multiple devices can fit into that
Hey, thanks for suggestion, Is there any desktop client also available for windows ?
I am receiving the values of wireless sensors from wireless modem which uses 900hp-s3b-Pro device connected with USB port.
You can setup a simple C# CLI or a winforms app to read the serial port, and use the NEM C# SDK to interface with the blockchain There is ready-made desktop client, I think you could make that pretty easily with the above tools ^^
