Ontoto’s Environmental Monitoring System, The next-generation weather station that delivers unmatched accuracy to your data.

ontoto environmental monitoring system and air quality sensor

A weather station so advanced, yet so simple to setup and use. The Environmental Monitoring system can be easily set to record data at any interval. From as little as one minute, up to one year. Don’t sacrifice the integrity of your data with manual logging, our data is sent autonomously via 4G straight to your web portal.

access your data in real-time via the Ontoto API

Your data, wherever you need it

Access your data in real-time from your web browser & mobile devices. Export your data easily as a CSV file to import to other applications like SCADA and Excel. Integration is simple & secure with Ontoto’s API, so you can access your data literally anywhere at anytime.

A secure & reliable data solution with redundancy built in

Designed with security & redundancy in mind, backups of your data are safely stored via the cloud & on the device itself, giving you total peace of mind on your data’s integrity.

secure backup and access to data
ultra low power data logger

Ultra energy-efficient, zero-emissions data logging.

The Environmental monitoring system is ultra energy efficient (with a sleeping current of only 2 micro-amps) & powered by solar & battery, giving you an ultra reliable and maintenance free logging solution.

Seamless integration & data migration with other data logging solutions

By design, our devices and software integrate seamlessly with other solutions such as the hobo data loggers and In-Situ monitoring solutions.
