Water Quality Station (Salinity, TDS, Conductivity and Temperature) - IC-SNiP-SAL-SL
The SNiP-SAL is a 'Sensor Node Integrated Package' for LoRaWAN or CAT-M1 communication of real-time salinity, TDS KCl, conductivity, and temperature measurements for continuous water quality monitoring.
The base SNiP-SAL integrates 1x S-NODE and 1x AWQ-C4E Conductivity/Salinity Sensor to a site's unique network, communication and power requirements. The S-NODE can support an added 3x Sensors. The AWQ-C4E sensor has been designed to measure Salinity, TDS, Conductivity and Temperature.
S-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.
