Wireless Sensor Interface

Integrated Sensor Interface reduces cost and enables ultra-low power design.

xSM, sensor interfacing RF Networks

The xSM 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 169MHz MSM modules and for the Sigfox sensor modules

The xSM products includes:

  • RC1682-SSM, a sensor interfacing Sigfox module that is intended for the European markets
  • RC1692HP-SSM, a sensor interfacing Sigfox module that is intended for the Americas and Asian markets
  • RC1701HP-MSM, an ISM band 169MHz module that provides very long range
  • RC1880-MSM, an ISM band 868 MHz module that provides very low power
  • The Radiocrafts sensor board, that supports includes the supported sensors and is a great tool for prototyping a wireless Sensor network.

The base-stations is the xSM Wireless Sensor Network (WSN) is divided in two categories.

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

  • The MSM modules are based on Wireless MBUS and can connect to any Wireless MBUS gateway that supports either 169MHz or 868MHZ. Radiocrafts also offer IoT expansion boards that can interface to the MSM modules and can be easily integrated into a FX-30 Gateway from Sierra Wireless or a MangOH Red board. Radiocrafts provides the source code to the demo software used to connect the sensors to the cloud. 

  The tools supported are:

  • The CCT tool for Sigfox resp Wireless MBUS includes the SSM and the MSM
  • 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.
