SimpleLink Sub-1 GHz: Sensor to Cloud

End-to-end solution for low power wide area networks (LPWAN) enabling cloud connectivity for sending and receiving sensor data over a long range Sub-1 GHz star network.

Sensor to cloud

Sensor nodes

The sensor node example application is a part of the TI 15.4-Stack software that is included in the SimpleLink CC13x0 and CC13x2 SDKs. The TI 15.4-Stack is a complete Sub-1 GHz network solution providing key features such as network management, security, and a frequency hopping scheme. 

The TI 15.4-Stack sensor node example application can be demonstrated using the following SimpleLink Sub-1 GHz development tools:


The SimpleLink Sub-1 GHz Sensor to Cloud gateway is the central node of the star network, which integrates advanced security features for a bidirectional link between the sensor nodes and the cloud.

TI offers flexible gateway solutions based on the following architectures:

Cloud partners

The IoT Cloud Application communicates to the gateway allowing sensor data to be received and sent through a cloud-based user interface.

The solution is demonstrated through cloud vendors such as AWS and IBM Watson IoT. In addition, the IoT cloud application features a flexible interface to allow the user to connect to their cloud partner of choice.
