UC Technology has released a Tweeting Sensor, which regularly posts temperature and humidity data to Twitter. The Tweeting Sensor can be checked remotely on Twitter via a smartphone, cellphone, or PC.
"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."
If the wireless sensor is posting temperature, humidity, and sunshine data every minute, it can run for about a year on three AA batteries. The sensor can also be set to sound an alert if specific values are reached. So this product can be used to manage the temperature in locations such as wine cellars or food warehouses. It can also be connected to a radiation meter.
"This wasn't planned at first, but we've made a unit that can be connected to a commercially available radiation meter. This enables the Tweeting Sensor to post radiation data to Twitter. If lots of people post their readings, it would be possible to create a detailed radiation map."
The basic unit is priced around US$520 (40,000 yen), and UC Technology aims to sell 10,000 sets annually.
