Japan-based UC Technology Corp. [JP] has developed a wireless sensor that can automatically post data like temperature, humidity, illuminance, or radiation levels to Twitter. The so-called “Tsubuyaku Sensor” [JP, PDF] is mainly designed for use in food warehouses, plants, or wine cellars.
The data can be checked remotely on Twitter (the account can be set to private or public). UC Technology says that the sensor has a battery life of a year when it posts data once per minute.
The company explains:
You connect this device to the Internet and plug in the AC adapter. You can also connect a slave unit, so you have a wireless sensor that measures temperature, humidity, and sunshine. This sensor makes the wireless connection automatically, and sends its data each time. The connection range is about 40 m, but if you want to make measurements even further away, there’s a relay unit as well. That’s used by plugging it into a wall socket and it extends the range to 60 m.

UC Technology plans to start selling the sensor in Japan this month (prices: US560 for the base unit, US$286 for each sensor).
