Optional modules include, for example, various communication
modules, and built-in pressure transducer.
MAWS is a low-power system. The logger consumes less than 10 mA
from a 6 V battery (5 mA from a 12 V battery). MAWS can be powered
using a solar panel or optionally using a 110/230 AC power supply.
External DC supply (8 to 14 VDC recommended, 30 VDC max) can
also be used as the main power source for MAWS.
The power consumption of the complete MAWS system depends on the
connected sensors, communication devices, and other options included
in the delivery. For example, MAWS with the basic set of 5 sensors,
each having 10-minute measuring interval, has an average power
consumption of 10 mA / 6 VDC (5 mA / 12 VDC).
Internal Battery
Normally, the internal battery QMB101 is used as the primary power
supply. The battery is recharged by the integral charger in the logger,
accepting input from a solar panel, mains adapter, or an outdoors mains
power supply. The internal battery QMB101 is placed on top of the
circuit board, under the logger cover.
