Introduction
A measurement path is the structured way in which a gateway sends information so that the Calculus platform can process it.
The structure of a measurement path
A measurement path can be composed in two ways:
GATEWAY|SENSOR
GATEWAY|SLAVE|SENSORIn reality, the paths will always look something like this:

Gateway: the main device to which one or more slaves or sensors are connected. It ensures that the data is all converted to the same format, and then delivered to the Calculus platform.
Slave: the bridge between a sensor and a gateway. You can think of it as the input that the sensor uses to deliver readings to the gateway.
Sensor: a device, module, machine, or subsystem whose purpose is to detect events or changes in its environment and to transmit the information to other electronics, in this case, the slave or gateway.
Attention!
The slave part of the measurement path is optional, and will therefore not be present in all cases. In some cases, the slave can also be a gateway. When a sensor is already connected to a gateway, and that gateway is connected to the main gateway, the slave element of the measurement path will be a secondary gateway.
