Power Considerations
Under typical conditions the hydroSpider2 can run for an extended period of time (up to 5 years)
before requiring a battery replacement.
To achieve the lowest power consumption setup (and therefore the best battery lifetime), consider
the following:
The reporting period should be set to what the application requires, and no faster. The
biggest power consumer in the hydroSpider is the internal modem. Reporting uses the
modem, and therefore reporting more frequently has a dramatic effect on the power
consumption of the unit.
The logging period should be set to what the application requires, and no faster. More
frequent logging generates larger reports, which require a longer time to be sent via the
modem (and therefore consume more power). In addition to this, the act of logging itself
consumes power, especially when the connected sensors require warm-ups.
o
If data (or faster logging of data) is only required under certain circumstances,
consider using the Fast Logging feature of an alarm.
Switch and Event channels log a record every time they change. Therefore these channel
types are suitable for monitoring pulses that occur less frequently than once every 30
seconds. If logging of higher frequency pulses is required, it is recommended to choose
either the Counter channel type.
