Enabling better global research outcomes in soil, plant & environmental monitoring.


The SNiP-AWS5 is a 'Sensor Node Integrated Package' for LoRaWAN or CAT-M1 communication of real-time ambient temperature, humidity sensor, atmospheric pressure, wind direction and wind speed for continuous environmental monitoring.

SNiP-AWS5+ Package:

The SNiP-AWS5+ package integrates 1x MFR-NODE, 1x AWS500, 1x SP-110 Solar Radiation Sensor, and 1x RIM-7499-STD Rain Gauge to a site’s unique network, communication and power requirements.

The AWS500 measures air temperature, relative humidity, air pressure, wind direction and wind speed, with high precision, fast response time and configurable wind speed and direction sampling periods. The SP-110 Solar Radiation Sensor measures solar radiation from 360nm~1120nm; The RIM-7499-STD Rain Gauge measures rainfall, constructed for accuracy and long-term operation with minimal maintenance.

This SNiP also includes:

  • a sensor mounting bracket;
  • 1x 6.5Ah rechargeable li-ion battery;
  • 1x 10W Solar Panel; and
  • 1x SPLM7 mounting system for node and solar panel.

The modular nature of ICT International SNiPs allows for SNiP-AWS5+ to be customised with alternative solar radiation or rainfall sensors. These or other further parameters can be added to the SNiP, without requiring loggers to match each distinct sensor, substantially reducing the cost of getting a fuller picture on the application.


The Multifunction Research Node has been designed to provide flexible communication, sensor and power options.

The MFR-NODE supports SDI-12 and 4 x dry contact digital inputs as well as optionally 2x differential / 4x single ended analogue inputs. The MFR-NODE supports sensors with higher power requirements; a solar panel can charge either the internal lithium-ion battery or both the node and sensor can be powered by an external 12V system (e.g. battery or mains source). Optional CAT-M1 provide an option for remote installation and in areas outside the range existing LoRaWAN networks. The optional multiconstellation GNSS ensures you won’t lose track of your device. The MFR-NODE has an onboard 8GB SD Card to provide data logging capabilities and full data redundancy in the event of temporary loss of communications or dropped packets – ideal for research applications.

  • LoRaWAN™ low-power long-range connectivity
  • 8GB SD Card for data storage
  • Supporting SDI-12, 2 x 32-bit dry-contact counting digital inputs.
  • Optional 24-bit ADC for 2x differential / 4x single ended sensor.
  • Optional CAT-M1
  • Solar rechargeable Lithium-ion or external 12V power options
  • Optional Multi-constellation GNSS
  • External solar/battery input: 12-32V DC.
