On 1 July 2025, NIWA merged with GNS Science to become Earth Sciences New Zealand.

Data collection instruments (loggers)

Data loggers range from simple standalone recording devices that can be manually downloaded, to Internet-capable remote terminals that can push their data to a server that users can access via an Internet browser.

Data loggers range from simple standalone recording devices that can be manually downloaded, to Internet-capable remote terminals that can push their data to a server that users can access via an Internet browser.

At NIWA we mostly use data loggers manufactured by our Perth-based subsidiary, Unidata PTY. We have a say in the design and can feed back any useful changes to enhance a product as we use it in a wide range of practical applications.

As unlimited access to historical and real time server-based information becomes more widely known and appreciated, the demand for Internet capable loggers is growing. However there is still a place for basic loggers in applications where accessing the data isn't urgent or the project can't support the ongoing server and ISP costs associated with telemetry.
