Healthy Strings

Bluetooth humidity & temperature sensor designed to protect instruments from extreme conditions.

What's the big idea?

Healthy Strings is a Bluetooth® Smart enabled humidity and temperature sensor with a companion smartphone app. 

As winter fast approaches, it brings with it cold, dry air that has the potential to damage wooden instruments if they are not given proper care.  Healthy Strings monitors the temperature and humidity inside your instrument’s case, providing real time data back to your smartphone.  The app will then alert you any time the humidity or temperature are outside the ideal range.

How are you different from that player?

Healthy Strings is a universal device that can be used in any instrument case.  Healthy Strings is also less expensive with a target price of less than $50.

How does this idea scale into a big business?

2.4 million guitars were sold in 2013 at a retail value of over $1 billion.  Healthy Strings is not just for guitars; it’s a tool for violins, violas, cellos, and pianos.  Every wooden instrument is vulnerable to changing humidity and temperature giving Healthy Strings a large target audience.

Why are you the one to run with this idea?

I discovered a need for a device like this in my own life and had the initiative to develop a prototype using the Texas Instruments SensorTag.  I also have the necessary background in technology and music to make this idea succeed.

What is a $5,000 experiment you can do to move your idea forward?

1) Evaluate demand by creating a product website and collecting email addresses of those interested.  2) Continue development of the app prototype.

    Were this a kickstarter, I would have backed it. Best luck - this would be great for those of us who have multiple instruments in storage, if the app were to support multiple distinct humidity sensors.

    Rich, the end goal would be for the app to support multiple devices with the ability to name each device you connect to.  Most developers have found that iOS devices can support about 20 simultaneous Bluetooth Low Energy connections so it’s definitely possible.  As far as a Kickstarter goes, that may be coming soon to help further validate Healthy Strings desirability.
