Easiest Way to Get Data on the Cloud
The OleumTech® Sigfox Ready SFX-AD81 Wireless Analog/Discrete 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-AD81 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 SFX-AD81 contains a cryptographic token that is computed based on this authentication key and verified by each Sigfox Base Station.
High Versatility
The SFX-AD81 wireless sensor node is equipped with a 24-bit high resolution analog input (AI). The input can be configured for 4-20mA or 0-10 Vdc mode when the node is externally powered. 0-10 Vdc mode only when powered by an optional battery pack. The SFX-AD81 is also equipped with a discrete/digital input (DI) for alarms and exception reporting when critical state changes occur. The DI can be utilized as a low-speed pulse counter, up to 2 KHz. The SFX-AD81 is designed for general purpose use in non-hazardous locations.
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.
