In 2015 true remote telemetry devices did not exist.  Ontoto’s Managing Director, Tim Blake, decided it was time for that to change and started designing and manufacturing data loggers that provided truly remote telemetry solutions to the environmental monitoring industry.

The Ontoto solutions are designed and manufactured in-house and over time we have learned many things.  Data loggers should be easy to install and use; they should be cost effective; they should have a long technology life; they should have long battery life; and, most importantly, they should be reliable.

The Ontoto range includes data loggers for groundwater monitoring, vibrating wire loggers, water metering, tipping rain gauges and environmental monitoring. Our devices now utilise 4G, NB-IoT and satellite communications.  Couple this with our Ontoto Data Management, Ontoto provides the entire solution for managing your data.

The current standard telecommunications network cannot guarantee reliability of coverage across Australia, let alone across the world.  Many of our clients are operating in areas that are remote and do not have cellular coverage.  This is why the Ontoto devices are all designed with a satellite connectivity alternative.  It provides a guarantee to our clients that they can get their data to their desktop from anywhere in the world, and it offers a solution with longevity.  We have also ensured that the costs of our satellite solutions are comparable to cellular costs.

We are extremely proud of our products and the customer service we offer.  Our team is always ensuring our products are cutting edge and maximising the technologies available. 

Ontoto – providing world-class remote telemetry solutions to protect our natural resources.

Capable of withstanding Australia’s harsh environment, the Ontoto IP68 range of products ready for any application.

Our Australia Footprint
Ontoto designs, manufactures and supplies ultra-low power, low cost telemetry data logging solutions. We have developed the firmware and hardware designs to suit the needs of Hydrogeologists and Environmental Scientists. All our products and services are designed in-house using emerging technologies and are designed to provide an all-in-one solution to fulfil all requirements in any location. Each data logger is capable of using an array of intelligent digital sensors, collecting sensor data at frequencies ranging from every minute to every year and utilises NB-IoT and satellite networks as methods for communication and data transmission.

Our data loggers come pre-configured (batteries included) ready to be installed. Our remote telemetry packages are a drop-in, turn key telemetry data logging solution designed to fit within a standard water bore monument with a single bolted connection. Logging and communications are supported with a comprehensive cloud monitoring platform.

Data is available in real-time through the web portal and the Ontoto Connect App. Your data can also be easily integrated into your projects thanks to our secure and simple to use Application Programming Interface (API). Your data can also be exported as a CSV file for use in a variety of other applications. Designed with redundancy in mind, a copy of your data is also securely stored to the device itself.

All this in a small, compact, cost effective solution.
Feature Description

The Ontoto Connect mobile app allows onsite management of the data logger to be undertaken wirelessly via BLE. There is no need to connect a laptop directly to the device. The Ontoto Connect Android and iOS application provides a gateway to communicate with the loggers and their data, providing customers with a fast and efficient way of initially installing and configuring their device and giving data insights at a glance. 

The key features

Configure the device name, sampling period,transmission period, and alarm threshold.

Available firmware updates can be downloaded from the Ontoto server and uploaded to the device.

The device will scan through each connected sensor. The measurements of each sensor and any detected errors will be displayed.

Tests for Satellite connectivity and signal strength and displays any detected faults.

The location of the device will be updated with the GPS coordinates of the phone and transmitted to the Ontoto Web Portal.

The device stores all recorded data in persistent memory for redundancy and auditing purposes. The data log is processed into a CSV file.

While using the app, the debug log received from the device is automatically streamed to the Ontoto server, allowing for seamless debugging during deployment.

App Installation

To install the Android App or IOS version you can use the links below

Ontoto's Web Portal is a free, web-based portal that allows you to derive parameters, get statistics, generate reports and visualise your data, all in real-time. The Ontoto Web Portal allows our customers to view and manage their data even when they are away from their primary computer. Data is sent from the logger(s) to our MySQL database on a remote server and published with user/password security. The web-portal provides both real-time and historical data in table and graph format. Data can be downloaded from the web page in CSV format when required and can also be sent to a third-party SCADA system. In addition, the Australian Bureau of Meteorology data is included in the web-portal.
