Water is one of nature’s most important gifts to mankind. Although water covers more than 70% of the Earth, only 1% of the Earth’s water is available as a source of drinking.Telemetry is important in water management, including water quality, stream gauging functions and equipment surveillance. Nowadays, the availability and widespread use of the Internet, coupled with advances in wireless telemetry, provides the forecaster, and other users, with a powerful set of tools to obtain real time information on which to make decisions.
Uses of water include agricultural, industrial, household, recreational and environmental activities. Nowadays, automation and remote control systems are spreading among water management infrastructures, either in drinking water or irrigation water supply networks.
The unattended and remote nature of many water management applications as river level & flow gauging, groundwater monitoring, lake and reservoir level monitoring, leak detection in distribution pipelines, sewer water monitoring, implies the need to operate from a DC power source, such as a battery.
