Cellio – LoRa Transceivers Wirelessly Enable Sensors and Sensor Instruments for IIoT/M2M



With 16 General Purpose Inputs and Outputs (GPIO) on each Wireless LoRa Transceiver, Cellio Transceivers are designed as agnostic as possible to support sensors you may want access wirelessly to collect, visualize and analyze data from assets in the field and throughout your operations.   Companies with existing sensors and sensor instruments already in place can quickly and affordably move from manual data collection (and paper based logs) to a more real-time and automated environment – and all the advantages and benefits that come with having data that is provided more regularly, more accurately, and electronically. At a minimum, the data can be used in a simple tabular format to get a consistent assessment of the status of assets in the field. At maximum, the collected data can be connected to back-end supply and logistics systems to help improve the performance of the business operations. Cellio is designed to get data from where it is to where you need it be.

Cellio Transceiver Input Options

In order to support the broadest array of applications and industries, Cellio Transceivers have been designed to support the following input types:

  • Analog Inputs
    • Voltage
    • Current
  • Digital Inputs
    • Trigger
    • Digital State/Transition
    • Pulse Width
    • Pulse Count
    • Bus (ie RS-232, RS-422, RS-485, SPI, I2C)

With this variety of configuration options, the Cellio Wireless Transceivers can be easily and readily adapted to interface with most any sensor or sensor instrument that you may already have, or may be contemplating installing, in your field operations.

Connecting Sensors to Cellio Wireless Transceivers

The most direct connection of a sensor to Cellio Wireless Transceivers is either through an analog or digital pin/wire to the input connection of the Transceiver. For example, a simple temperature sensor that has been internally reference and tuned (ie Digi-Key Electronics or Mouser Electronics) can be connected to the Transceiver provided PWR and GND and the output from the temperature sensor connected directly to an Analog input signal. Additionally, a simple slide switch can be connected to the same PWR and GND pins and the center pin of the slide switch connected directly into a Digital input on the Transceiver. In this way, a very low cost set of sensors (up to 16) could be connected to any Transceiver and the collected data sampled and reported to the Gateway device(s) and then transmitted to back-end data storage/analytic/visualization systems. Additionally, for inputs that generate pulses (ie flow sensors/meters) the width of the pulse can be measured as well as the number of pulses. If the slide switch (or a pushbutton or other digital signal) is configured on the Transceiver as a Digital Trigger, the change in state of the digital signal can be used to force the Transceiver to transmit to the Gateway and the Gateway then immediately sends off an SMS or Email to a preconfigured list of notification destination(s). If other preconfigured thresholds are identified by the Transceiver, they too can be used to immediately notify the gateway with a report of the status of the sensors and instigate immediate notifications and data transmissions to the back-end.

Connecting Sensor Instruments to Cellio Wireless Transceivers

A likely scenario for many Cellio Wireless Transceivers is to connect to existing sensor instruments already in place in field operations. For example, an instrument that has an electronic read-out (and is powered electronically) is already in place to measure the depth of a liquid or powder in a holding vessel. In this case, the sensor instrument may provide a single analog or digital signal to indicate the measurement in which case, as described in the previous section, the Transceiver would evaluate the signal as a basic input signal. In the case where the instrument transmits readings over a bus (RS-232, RS-422, RS-485, SPI, I2C, etc.), the Transceiver can be configured to communicate natively in the required bus protocol and the resulting readings can be used similar to the readings from direct analog and digital inputs. If other preconfigured thresholds are identified by the Transceiver, they can be used to immediately notify the gateway with a report of the status of the sensors and instigate immediate notifications and data transmissions to the back-end.

Bonus: Reporting Sensor and Sensor Instrument Readings

An important capability of the Transceivers and Gateways is to balance the need to keep power use to a minimum (maximum battery life), support the maximum number of Transceivers per Gateway (minimum CAPEX investment), and reporting immediately on events of interest (high priority alerts, exceptions, etc.).  Cellio Transceivers and Gateways have been designed and can be configured to use sensor and sensor instrument inputs to quickly evaluate local readings against pre-set thresholds and then use those results to either report in immediately, more frequently than typical operational parameters, or as infrequently as needed. Thus, input signals can be used to identify conditions that need immediate attention so that users are notified with alerts as soon as possible to address both favorable and unfavorable conditions. This configuration capability allows users to directly benefit from both simple local network installations to full enterprise installations where process owners, managers, and key personnel can all benefit from specific alert conditions and kept in the loop to pay attention to only those items they need to pay attention to on a real-time basis. They can then rely on hourly, daily, or weekly reporting from the back-end for summary information. In this way, returns can be realized immediately from the very first installation of the very first Cellio Wireless Transceiver.

Cellio Wireless Transceivers provide a wireless link from sensor and sensor instrument devices to Cellio Wireless Gateways via 900MHz LoRa with a transmission distance of a approximately 1 mile (3 square miles). The Transceivers can effectively wirelessly enable existing sensors and sensor instruments that are already in place in field operations – thus providing the least expensive and quickest path from manual paper logging to automated electronic data logging, reporting, visualization, and analytics. So whether you are installing new sensors and sensor instruments, or trying to retrofit an existing installation, Cellio Wireless Transceivers can be configured to fit your needs.
