The SSM sensor interfacing RF Networks are designed to:

• Support Wireless Sensor Network with a minimum of components in the Bill of Material.
• To be very low power.
• To be very easy to implement.
• To have long range, several kilomteres for the SIGFOX sensor modules.

The SSM products include:

• RC1682-SSM, a sensor interfacing SIGFOX module that is intended for the European market.
• RC1692HP-SSM, a sensor interfacing SIGFOX module that is intended for the Americas and Asian markets.
• The Radiocrafts sensor board, which includes several supported sensors (listed at the end) and is a great tool for prototyping a wireless sensor network.

• The SIGFOX system relies on a cellular base-station network deployed by SIGFOX. The user buys a subscription from SIGFOX and gets Cloud connectivity via the SIGFOX network.

  The tools supported are:

• The CCT tool for SIGFOX.
• The configurator tool to set the sensor interface parameters.
• The development kit that includes the sensor board.

There are 4 types of sensor interfaces supported:

1. An analog interface that reads the voltage level between 0 and 1.25V, in steps of 0.01V, from a sensor.
2. Digital GPIO, that can be configured for input or output.
   • As output it can be set to toggle or drive a high or low signal.
   • As input it supports sensors with digital output, such as many magnetic sensors.
3. The I²C interface supports a variety of predefined sensors. See the Data Sheet for details.
4. The SPI interface supports predefined sensors. See the Data Sheet for details.

An event controller inside the Radiocrafts module determines when a sensor is read and when data is transmitted to the wireless network. The sensors are read by using either a time cycle, where the cycle time is decided by the user at configuration or by hitting a trigger condition that can be configured by the user. The transmission to the network is set in a similar fashion, either where data from the module is sent at a customer-defined time-interval or when a trigger condition is met. See the User Manual for more details.

The sensor board supports the development of Sensor nodes using Radiocrafts Sensor Interface modules. It is included in the development kits for those modules.

The Sensor Board is populated with the sensors in that table below.
