D'Addario presents the Humiditrak, a Bluetooth sensor described as "the world's first 24/7 instrument monitoring system".
Humiditrak allows you to keep track of the humidity and temperature levels of all your instruments with a discreet Bluetooth sensor, free app and push notifications. Basically, all you have to do is put a sensor in the case of each of your instruments, then monitor the humidity and temperature each of them is submitted to in real time using the iOS and Android compatible free app. And, when dangerous conditions are detected, it sends push notifications to your device, so you can take action before damage occurs.
The Humiditrak is already available for a MSRP of $49.99. More details at www.planetwaves.com.
