Appendix 1 – Emerald battery life
Many factors have an influence on Emerald battery life, both during use and in storage
before being used. Here are the main considerations to take into account when evaluating
product battery life:
•
Ambient temperature
: battery capacity is diminished when subject to very cold
operating and/or storage conditions.
•
Wireless communications
: Bluetooth connections, from the OCEAView software to
the Emerald module, consume battery power. Logically, the more you connect, the
more you use the battery.
However, it is worth noting that no connection is established when using Emerald
with the OCEABridge gateway, or when simply viewing Emerald devices in OCEAView
(without going into details). In that case, only the Bluetooth advertisement frames
are read, and Bluetooth emits those frames regularly, whether or not you connect.
Note:
The reading frequency does not have significant impact on battery life. Because of
the product’s optimized electrical architecture and circuitry, there is no significant
difference, in terms of battery life, if the sensor reads and stores data once every
ten minutes or once every minute.
