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


The SNiP-ATH2 is a preconfigured 'Sensor Node Integrated Package' for LoRaWAN or CAT-M1 communication of real-time microclimate humidity and temperature for continuous environmental monitoring.


The SNiP-ATH2 integrates 1x S-NODE and 1x ATH-2S Ambient Temperature & Humidity (SDI-12) Sensor to a site’s unique network, communication and power requirements.

The ATH-2S provides a measurement on Ambient Temperature & Humidity, and with a far higher accuracy drift of better than ±2% Relative Humidity. Another substantial development of the ATH-2 Series design is the removable sensor chip, which can be quickly swapped out in the field for a price far lower than the typical calibration or complete replacement. The ATH-2 Series instrument does not need to be fully removed from the site, freighted and then reinstalled for simple calibration maintenance. This advancement significantly reduces the time, hassle and costs associated with avoiding data gaps and maintaining long-term data integrity.

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 S-NODE can support 3x additional sensors to the base package.


The S-NODE (for Environmental Monitoring) has been designed to support the broad suite of SDI-12 based environmental sensors. The S-NODE can support 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).

A decoder suitable for TTN will be provided based upon sensor configuration.
