The Whisker.IO Engine™ is a small, bi-directional surface mount wireless module capable of long battery life and extended range of >1 mile (20miles with sufficient elevation). This FCC approved module is perfect for IoT applications; simply provide power and connect the sensors and actuatores you want to use. The modules can operate in a master-slave arrangement for IoT, M2M and sensing applications. It can also operate in a peer-to-peer arrangement for wire replacement applications.
The Whisker.IO Engine™ is a self-contained "wireless sensor in a module" that offers amazing range performance, awesome battery life, and two way communications (transmit and receive). The module has an on-board controller that can be configured to operate as a sophisticated node in an IoT wireless sensor/control network or as transparent serial link for wire-replacement applications.
For IoT applications, the module is very simple to use. One module is connected to a processor or micro with Internet connectivity and acts as a gateway; other modules are configured as nodes that can measure and control the world around them. Every module can operate as a gateway or a node, reducing the need to keep different SKUs in inventory. Gateway modules are commanded locally via the UART port using AT commands. Node modules are commanded remotely from the gateway using remote AT commands.
Building Whisker.IO™ nodes is very easy; just connect power and I/O. They can be powered from 3.0V or 3.6V batteries or from a regulated power supply and can operate for up to 5 years from a single pair of AA batteries. The modules expose a UART, digital inputs and outputs, analog inputs, and an I2C port for I/O expansion. The power mode, I/O configuration, and operational configuration are set remotely via AT commands from the gateway module. Input sampling can be setup to trigger either on a periodic basis or when a specified event happens.
For wire replacement applications, the module is a perfect fit, creating a >1 mile UART-to-UART wireless link.
