  • If the sensor fails to respond, contact Product Support at Data Harvest. Please provide details of:  
    • The computer platform with and the EasySense app’s version number.
    • A description of the problem encountered. 

USB Port (4)

Use to connect to a computer or a charging unit.


For specific USB or Bluetooth connectivity instructions, please see the 'Connectivity' section of this documentation. 


For instructions on charging your device, see the section on 'Charging the Sensor'. 

Unique ID Number (5)

All Smart Wireless Sensors have a unique ID number. This number is identified within in the EasySense app, so that you can identify each sensor when making a connection.


Microphones 

This pack contains two microphones in a stethoscope format. Connected by the user, one is assigned to Port A and the other to B on the sensor input, in the Sensor End Connector (1), above.


Each microphone has a removable protective cover, located on the housing (4.5 cm diameter).


The microphones use 4 mm jack plugs (1.4 m cable length each) for connection to the sensor. For longer "time-of-flight" measurements, an extension lead of (3 m) to allow a 5.8 m separation between microphones is required (not supplied).
