Wireless Sensors in Your Utility

Individuals and organizations can use wireless sensors with many different kinds of smart applications.

A wireless sensor is a device that can gather sensory information and detect changes in local environments. The sensor can be a “wired” sensor, and it can connect to a smart Raveon Radio.
Sensors can connect in many different ways:

  1. RS-232 serial port.  The RV-M7, RV-M21 and RV-M22 have RS-232 serial ports on them to connect to your sensor.
  2. RS-485 or RS-422 serial port.  The RV-M21 and RV-M22 have RS-485 or RS-422 serial ports on them to connect to your sensor.
  3. Voltage Input. The RV-M21G and RV-M22G Tech series radios have analog inputs to measure and transmit voltage readings.
  4. 4-20mA inputs.  With a resistor, the RV-M21G and RV-M22G Tech series radios have analog inputs to measure and transmit current readings.
  5. Digital inputs and outputs. The RV-M21G and RV-M22G Tech series radios with FIO interface have Flexible TTL IO interfaces.
  6. Pulse Counters.  The RV-M21G and RV-M22G GPIO nad FIO interfaces count digital pulses, and you can query them with MODBUS to get the count.
  7. On the GPIO radio, you can connect SCADA Sensors to Monitor that output 4-20mA. The GPIO will mimic the sensor a long ways away to this modem with Current Loop Output CLO that will output the 4-20mA signal in.

Wireless Communication Range

Raveon’s radios are Long Range data radios.

Star typologies rely on the wireless data links between the sensor and the central hub. Range can be an issue since there is no means for an intermediate “hop” or repeater of the signal. Also, scaling depends on the gateway’s capacity to support additional nodes.

Our Radios and your system can be very long-range and cover wide area because:

  1. All Raven Radios can be “store-foreward” repeaters.  Put one ore more on top hills or towers to cover large areas. These are reliable low-cost repeaters.
  2. Our Cigorn Gateway can be used to connect dozens or hundreds of base stations to your system. Scaling depends on the gateway’s capacity to support additional nodes, and Cigorn makes this work easy and reliable.
  3. The radio modem data rate can be set to the rate you need to be successful with.

For more information about RF Data communication, see this RF Range page.

All Raveon radios can “Repeat”  Don’t try to mesh!
There are a number of significant problems with mesh networks. Mesh networks require much more complicated protocols to form the network and relay data at run time. A major disadvantage is that mesh networks consume much more power than star typologies. Often mesh networks are used as a quick fix for the lack of range, making it harder to justify the costly up-front investment. The reliability of a mesh network relies on ALL radios, where a repeater system relies only on repeaters you install in reliable areas.

Daisy Chain your Network

Use long-range RF or Ethernet connections to remote areas, and then use a low-cost miniature RF modem to daisy-chain remote sensors to your long-range connections.
