Environmental monitoring at the highest high-tech level:
Data loggers for remote data collection & long-term monitoring
The company OTT Hydromet GmbH is a leading expert in the field of sensors and data acquisition systems offering professional solutions for measuring and monitoring the water quality, quantity and telemetry of the entire natural water cycle in the fields of Hydrometry, Hydrogeology, Meteorology and environmental technology.
In order to develop low power web connected data loggers for use in hydrology and meteorology stations, the company OTT Hydromet GmbH took advantage of the entire EUROS technology portfolio: EUROS RTOS, EUROS Development Environment, EUROS Web Server, as well as the EUROS File System, EUROS USB Host Software, diverse device driver packages like serial, I2C, USB, Ethernet, SPI, GPIO, audio and a customized board support package (BSP) including extensive use of the EUROS engineering services. Functions such as remote maintenance, remote control, remote update and remote diagnostics could be implemented by using a variety of EUROS communication protocols like TCP/IP, HTTPS, HTTP, SMTP, FTP, DHCP, NTP, POP3, PPP, SSL and TLS.
A special challenge was to establish a stable and reliable web services connection to all different internet and mobile networks provider spread all over the earth surface: from Australia over Europe to South and North America and adhering to the highest security standards based on the TLS 1.2 security protocol.
Another challenge for the EUROS RTOS was always to keep the device running in the low possible power mode in order to the save energy for the application thus extending its operation range for more than 10 years.
Sometimes the OTT Hydromet GmbH devices are placed in the wild nature outside of any human reach and are expected to deliver reliable services over years. In such cases mechanisms provided within EUROS related to the remote maintenance, debugging over TCP/IP and on the air software update are gaining a special meaning.
Relying on the EUROS´ technology and expertise in the field of embedded systems the company OTT Hydromet GmbH can deliver a logging and telemetry solution for every customer need, offering worldwide connectivity via internet and mobile networks.
