Easiest Way to Get Data on the Cloud

The OleumTech® Sigfox Ready SFX-TR81 Wireless Temperature Transmitter is designed for deployment anywhere in the world that Sigfox has network coverage. By leveraging the Sigfox Low Power Wide Area (LPWA) network, you can take advantage of the world’s leading Internet of Things (IoT) connectivity service, offering a software-based communications solution where all the network and computing complexity is managed in the Sigfox CLOUD.

Inherently Secure

The SFX-TR81 wireless IoT device takes advantage of the built-in Firewall, since it is not directly connected to the internet and does not use Internet Protocol. Layered on top of this secure foundation, OleumTech provisions each device with a unique symmetrical authentication key. Each message sent by the node contains a cryptographic token that is computed based on this authentication key and verified by each Sigfox Base Station.

Multiple Configurable Inputs

The SFX-TR81 wireless sensor node is equipped with two user-configurable temperature inputs. The RTD input mode supports Platinum-100 ohm 2/3/4-wire type RTD sensors with ±0.1 ˚C accuracy. The Thermocouple input mode supports type J or K. RTD and Thermocouple inputs can be used in any mix or combination.

Extremely Reliable

The Sigfox architecture is based on multiple base stations receiving each broadcasted and repeated message building redundancy into the solution. Data Integrity, availability and confidentiality are at the core of the offering.
