Automatic Weather Station - IC-SNiP-AWS5-SL

The base SNiP-AWS integrates 1x S-NODE and 1x MSO Integrated 5-parameter Weather Sensor to a site's unique network, communication and power requirements. Alternatively, for greater data redundancy the SNiP-AWS package can integrate the MSO with 1x MFR-NODE, as it houses an SD card which can retain a copy of the data on site. Both the S-NODE and the MFR-NODE can support an added 3x Sensors.

Built upon the MetOne MSO integrated 5-parameter sensor, the SNiP-AWS is an easily deployed, high accuracy system designed for industry-grade applications. Measurements are provided on Wind Speed (m/sec), Wind Direction, Temperature (C), Relative Humidity (RH %), Barometric Pressure (kPA), and Rainfall (mm).

Wind Speed and Wind Direction are measured using conventional cup and vane techniques. All other measurements are housed in a multi-plate naturally aspirated radiation shield to reduce solar radiation heating errors.

The temperature sensor is a platinum RTD. Relative humidity is a based on an accurate solid-state sensor designed for continuous exposure to adverse climates. The barometric pressure sensor is a robust piezo-resistive device featuring high accuracy and long-term stability. An external stainless steel 0.2mm/0.25mm precision tipping bucket rain gauge connects simply and allows for correct installation and siting per industry guidelines.

The system is powered by an 13Ah Li-Ion battery and 10 or 20W solar panel, scaled to suit the region of installation. The SNiP-AWS is supplied with all support and power and monitoring hardware making it a drop-in solution for any IoT Network.

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.

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

Features:

- LoRaWAN low-power long-range connectivity
- Supports the full range of SDI-12 commands, and sensors requiring constant excitation.
- Optional CAT-M1
- Solar rechargeable Lithium-ion or external 12V power options
- Optional Multi-constellation GNSS
- AS923, AU915 and US915 available, with other region plans available upon request.
- Standard IP65 enclosure, optional IP67

MSO Weather Sensor

The MSO is an integrated 5-parameter Weather Station. Wind Speed and Wind Direction are measured using conventional cup and vane techniques. All other measurements are housed in a multi-plate naturally aspirated radiation shield to reduce solar radiation heating errors. The shield consists of a series of concentric white aluminium plates, which allow air to flow through the shield while blocking direct solar rays.

The temperature sensor is a platinum RTD. Relative humidity is a based on our accurate solid state sensor designed for continuous exposure to adverse climates. The barometric pressure sensor is a robust piezo-resistive device featuring high accuracy and long term stability.

The MSO serial output can include data from an optional tipping bucket rain gauge. The digital serial data stream is output every second, or upon command by data system.
