Hey there,
I present the QBox!
I have named it thus because it reminds me of Star Trek and I loved the whole Q Continuum thing 
It is a bluetooth enabled, Voltage, Temperature and gas sensing device!
I work in the industrial industry of batteries (Forklifts, ect.) diagnosing / repairing them. So generally I'll be reading the voltage/temp/gravity of 12-24 cells and writing all that data down either on a computer or piece of paper. Forcing me to use a thermometer and a multimeter to achieve my goals.
Now with this I can use just the QBox and automatically capture that data into some custom software hands free so to say.
Video demo of the box in operation ect.
