SNiP-SI41 For SDI-12 Canopy Temperature (22° FOV)
The SNiP-SI41 is a 'Sensor Node Integrated Package' for LoRaWAN or CAT-M1 communication of real-time canopy temperature measurements for continuous plant, light and environmental monitoring.
The SNiP-SI41
The base SNiP-SI41 integrates 1x S-NODE and 1x Apogee SI-411 Infrared Radiometer (from the SI-400 Series) to a site’s unique network, communication and power requirements. The S-NODE can support an added 3x Infrared Radiometers.
The Apogee SI-411 Infrared Radiometer (from the SI-400 Series) is among the most accurate non-contact temperature sensors available anywhere. The SI-411 has an SDI-12 digital output and comes with a 22 degree half angle field of view.
Applications include measuring the temperatures of road surfaces, plant canopies, and soil, snow and water surfaces. Measurement of surface temperature is a crucial component of energy transfer. Accurate measurement of the leaf-to-air temperature gradient is essential to the determination of transpiration rate and stomatal conductance in both single leaves and plant canopies.

Further parameters can be added to SNiP-SI41, without requiring loggers to match each distinct sensor, substantially reducing the cost of getting a fuller picture on the application.
S-NODE
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.
