Sensor Operation Principles
The QE2008-W sensors communicate via Bluetooth 5�0 Low Energy directly with the "Sensormate" App, installed
on a mobile device or a Desktop computer. The "Sensormate" app is designed to read the sensor's strain measure-
ments and other parameters (e.g., the battery level, sensor orientation, firmware version, etc.) as well as to control
the sensor's operation (e.g., sampling rate, signal reset, LED colors, firmware upgrade, etc.).
The fundamental communication concept that regulates the behavior of the sensor is the Network.
A Network is an abstract concept that defines a group of devices which has to operate together. QE2008-W networks
are configurable, and can be composed by one or serveral devices.
Every sensor must be part of a network in order to be able to send measurements to the Sensormate App, and it is
important that, inside a specific network, sensor names are uniquely identified: two sensors with the same name will
lead to a conflict.
Discovered devices:
Network A - 1 device
Network B - 2 devices
Sensors belonging to different networks are recognized by the app
Sensors that are sold as part of a QE2008-W Set belong to the same network by default.
