iMETOS RadioNode MANUAL

 
Thank you for choosing an iMETOS® for monitoring soil moisture data and agrometeorological variables. iMETOS® RadioNode is a small, wireless, battery powered datalogger for in-field measurement of soil moisture, temperatures, rain, flow rate, leaf wetness, relative humidity and other parameters. iMETOS® RadioNode sends all sensor readings in real time through an interactive star network back to our base station. From the iMETOS® base station the data is uploaded to the web via cellular network (GPRS, Edge, UMTS, CDMA, WiFi). All data is available through FieldClimate platform.

Users have free access to data through web and mobile applications. Additional services (like plant disease models and hyper localized weather forecasts) are available upon license fee payment. Web API is available for interface with other custom applications.

iMETOS® RadioNode systems will be mainly used for:

  • Meteorological monitoring
  • Soil moisture and irrigation systems monitoring
  • Weather forecast corrected with local measurements
  • Plant disease models (depending on the configuration of the equipment)
  • Hydrology and flood warning applications
  • Environmental monitoring
  • Frost warning via SMS

5. MAINTAINING THE iMETOS


1. YOUR iMETOS RadioNode


To install iMETOS® RadioNode, you will need an RF Internal Wireless Access Point PCB (AP) and an RF Sensor Device PCB (SD). The Radio wireless AP is connected to the iMETOS® 3.3 through extension connector and is powered directly from the battery of iMETOS® 3.3. This internal wireless AP controls the network that iMETOS® RadioNodes are peered to.

The iMETOS® RadioNode consists of a white plastic case containing the electronics, the battery and the RF Sensor Device PCB (SD). Each RadioNode SD is powered by 3.6V Lithium battery (19000 mAh) or by 6V battery (4.5 Ah), has a built-in PCB antenna and can support many sensors (see below). You can connect up to 16 radio nodes to the main station with a star topology. The expected operating range is 300 to 400 meters (1200 to 1400 ft.) at +14 dBm. By line of sight, when mounted on level ground at least 3 m (10 ft.) high and above crops, grass, bushes or foliage, it can reach more than 1000 meters.

2. START-UP THE iMETOS RadioNode

  1. Open the housing by un-screwing the 6 screws downside.
  2. RadioNode-bottom

  3. RF Sensor Devices installation: Connect the sensors to the SD boards. Plug the battery into the SD board (LED indicator lights up for 2 seconds).
  4. RadioNode-connect the sensors

  5. RF Access Point board installation: Connect the RF AP board through the extension connector of iMETOS® RadioNode. Turn on the iMETOS® RadioNode (all LED indicators will light up one by one for a while).
  6. Peer button

  7. Device pairing (link establishment) between RF AP and all RF SDs.
  8.  4.1. Check if RF AP board is “ready to use” by clicking on the peer-button:
      • RF AP is ready to use (for pairing mode): The red LED diode is not flashing. You may pair a new sensor device.
      • RF AP is not ready to use: The red LED diode is flashing fast. RF AP has not been configured by the host device (iMETOS® station). In this state, RF AP board does not acquire any data and it is not possible to pair a new sensor device. This happens right after starting up. You need to wait until the RF AP board is ready to use (iMETOS® station should configure the AP board up to 5 minutes at latest).

     4.2. Activate device pairing mode on RF AP by pressing the peer-button and holding it for at least 3 seconds. Device pairing of RF AP is activated for 3 minutes.
      • All LED diodes of RF AP are lighting up for 1 second, after that only green LED diode is lighting up during active device pairing mode.
      • All LED diodes of RF AP are lighting up for 1 second, after that only green LED diode is lighting up during active device pairing mode.

  9. Activate device pairing mode on RF SDs by clicking on the external button. Device pairing takes 3 minutes.
  10.   •LED diode of RF SD is blinking during pairing mode.
      •When wireless link is established successfully, the LED diode on RF SD board turns off (within 3 minutes).

  11. It is recommended to do the pairing of other iMETOS® RadioNodes one by one, not all sensor devices at once. Repeat the steps above with all iMETOS® RadioNodes.
  12. 3. INSTALLING YOUR iMETOS


    With iMETOS® RadioNodes we can spatially extend our monitoring solution around the main iMETOS® 3.3 station for a radius from 50 m to 1000 m, line of sight, when mounted on level ground at least 3 m high and above crops, grass, bushes or foliage:

    • to monitor soil moisture in heterogeneous soils (soil characteristics can vary greatly over short distances);
    • in relatively homogeneous soils it could be interesting to monitor the soil moisture in different positions to have more spatially representative information;
    • in different parcels with different crops or varieties and/or different irrigation system sectors;
    • research applications with different small test plots;
    • different microclimatic conditions, in particular for example in green houses.

    *For simple configurations where distances are below 50 m, the application of the PI bus using sensors chain makes sense.

    NOTE: For complex configurations with more than 5 nodes we recommended contacting the PI Product Management for advice and revision of the draft project.
    Radionodes
    Picture above: iMETOS® RadioNode star configuration.

    The iMETOS® has to be mounted on the pole: At the bottom of the unit there is a plastic ring with a metal clamp on it. Make sure that the pole is as vertical as possible. Check the bubble level on the rain gauge to ensure the right installation verticality of the pole.

    If you have the solar panel, mount it on the main plastic case. In the northern hemisphere, it should face south while in the southern hemisphere it should point towards north.

    iMETOS® RadioNode for soil moisture monitoring comes with a set of soil moisture sensors. Each RF sensor device can support a set of soil moisture sensors. The soil moisture and temperature sensors have to be properly installed in the ground. Depth of placement depends on the application and varies with the rooting depth of turf or plant material. To install fork-like sensors, excavate a trench to the depth required and insert the entire sensing portion of the sensor horizontally into the undisturbed soil face. Let the cable go down first and then take it up to the top. This prevents water from following the cable in the ground and wetting the sensor. Soak Watermark sensors in water before installation. To install soil moisture profile probes, drill a hole with an auger and insert the probe carefully in the tapered soil opening, until the top of the probe is levelled with the soil surface. To ensure high quality of measurements, all soil moisture sensors should have a good contact with the soil around them.

    The leaf wetness sensor can be tied to a branch of the plant slightly inclined with the filter paper looking up. Mount it in a position that allows the sensor to pick up early rain and to stay wet in the shade.
    For detailed info about the installation of sensors refer to this page.

    Station settings > Warnings: You can add phone numbers and set thresholds for each sensor, at which the warning SMS should be sent.

    For further inquiries visit FieldClimate.

    5. MAINTAINING THE iMETOS


    The weather station should be checked periodically to ensure that sensors are in optimal condition. Regular maintenance is necessary for flawless operation and durability.

    At the beginning of the new season, check that the station is working correctly; data must be transmitted at the set interval to FieldClimate. Keep the solar panel and sensors clean and ensure correct rainfall measurements by making sure the rain gauge is leveled (check the bubble indicator), and not obstructed by leaves, insects or debris. Check if leaf wetness sensor has the appropriate filter paper intact and positioned correctly (it should be replaced once, preferably twice a year).

    When the solar panel of the iMETOS is exposed to the sun and gets enough sunlight it should constantly recharge the battery of the system. The lifespan of the battery is expected to be 5 to 6 years with sufficient recharging from the solar panel. Deep discharge shortens its lifetime. The iMETOS will prevent this from happening and protect the battery by limiting the data transfer to the safe level of charge. In doing so, data is not lost and battery recovers faster.
