• Limit the rate at which measurements are taken - if the parameter being measured changes slowly,
then measuring it regularly will consume additional energy without a benefit.
• Turn off sensors that are not required - the ORB contains a rich set of internal sensors. If for exam-
ple, the GPS is not required, turn it off.
• Choose external sensors carefully - a 4-20mA sensor may use more energy than a voltage output
sensor.
• Limit the number of daily transmissions - consider only transmitting data when warning and alarm
conditions are breached.
• Ensure that the ORB is placed in a position where GSM, Wi-Fi, and GPS reception is optimal. Far
more current is consumed when transmitting nad receiving in a poor signal environment.
Measured sleep, measurement, and transmission current is given in the table below. The measurements
in the table represent current flowing from the internal Lipo battery at 3.5V, with external power to the
ORB removed. Except where stated, the GPS is assumed off. Actual values will depend on the power
source, selected measurements, battery charge state, distance from Wi-Fi or GSM source and temperature.
Note A battery life calculator is available on the Senquip Website.

3.5 Battery life
Sequip has measured actual power consumption figures to determine the expected life when using AA
cells. Remember, when setting up for low power applications, that the ORB can make regular measure-
ments and only transmit once per day unless it enters an exception state (warning or alarm is active), in
which case a transmission is made immediately and the ORB switches to the exception interval, allowing
for faster transmission rates.
Note Battery life expectation is extremely difficult to estimate and will be affected by all kinds of parame-
ters such as temperature, battery chemistry, quality of reception, and sensors used. The numbers below
should be taken as indicative only.
