Microphone
The MEMS (Micro-Electro-Mechanical Systems) microphone is very sensitive, with a good signal/noise ratio and small form factor.
Connections
Connect the ULD sensor to your Android smartphone or tablet, and it will immediately be recognized as a new input. Additionally, you have to connect Bluetooth wireless headphone. With CALMS ULD Android software ULD sensor will be recognized and ready to find leaks. Next step is to log in to CALMS web service and sync data to start doing Leak Management.
See table for Android device compatibility.
Settings
ULD is factory set to work with CALMS ULD software. No field adjustment needed.
