New wireless monitoring for fish farmers and breeders developed in the UK

UK-based Wood & Douglas has developed a monitoring system that enables fish farmers to look after the welfare of their stocks and their on-growing environment while away from farm sites. Low-dissolved oxygen levels are responsible for more fish farm kills than all other problems combined. Should oxygen levels drop, Wood & Douglas’ Ultima GSM, a rugged wireless telemetry module, can be configured to send out alerts to one or more mobile phones and/or email accounts.

The environmental status can then be monitored via phone or an internet webpage, and uniquely, sending a text remotely initiates digital outputs which can be used to adjust heating and cooling systems or respond to changes in the chemical balance of the water. The Ultima GSM unit houses a quad-band GSM/GPRS module. Four digital inputs allow connections to a range of environmental sensors for monitoring temperatures, levels of dissolved gases such oxygen, carbon dioxide and nitrogen, as well as levels of ammonia or changes in pH.

It can deliver regular status updates, or be polled with a status request at any time by simply sending the unit an SMS message. Read more...
