Compact weather station - NIWA Tier2
A low-cost weather station for gathering accurate weather data. Wind speed and direction, air temperature, relative humidity, barometric pressure and rainfall data can be accessed from a server, via the internet.
The Tier 2 Weather Station is a compact, standalone, designed by NIWA engineers for low cost meteorological monitoring projects.
The Tier2 station records wind speed and direction, air temperature, humidity, barometric pressure and rainfall.
Parameters such as solar radiation, soil temperatures and soil moisture can be added if required.

Internal: Neon Remote Terminal (NRT) Datalogger and Communications Module
The Tier2 Weather station incorporates the NRT-Terrestrial is a small self-contained datalogger which is connected to sensors in the field. The NRT collects readings, and transmits the data to a central server using Unidata’s NEON IP cellular communications systems, from where it is available to end users.
Features
- Fully programmable datalogger.
- 32KB local data storage.
- Internet, enables (GPRS/CDMA/Satellite) real time communications.
- Low power requirement with solar charging.
- SDI-12 interface for connection to a wide variety of environmental instruments.
- In-built digital and analogue inputs for direct connection to sensors.
- Compatible with Unidata support systems.
