The SNiP-DOT is a 'Sensor Node Integrated Package' for LoRa, LoRaWAN, FSK or CAT-M1 communication of real-time Dissolved O2 & Temperature measurements for continuous water quality monitoring.
The base SNiP-DOT integrates 1x S-NODE and 1x AWQ-DO Optical Dissolved Oxygen Sensor to a site's unique network, communication and power requirements. The S-NODE can support an added 3x Sensors. The OPTOD Optical Dissolved Oxygen Sensor uses optical measurement by luminescence to measure dissolved O2 in water and water temperature.
S-NODE: SDI-12 Node:
The S-NODE 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). The S-Node's SDI-12 communications can be customised to allow for interfacing with any SDI-12 sensor.
AWQ-DO: Optical Dissolved Oxygen
