The above solar panel was tested with an ORB measuring and reporting 2 input voltages, ambient
temperature, ambient pressure and thermocouple temperature at an interval of 5 minutes. To conserve
energy in what was a fixed location test, GPS location was measured every 20 base intervals or 100
minutes. The reults were transmitted over GSM or Wi-Fi at 5 minute intervals. The solar panel was suffi-
cient to power the ORB.
3.2 Internal rechargeable battery
An Internal 3.7V, 1800mAh rechargeable Lithium Ion Polymer (LiPo) battery is charged from system
power, making the device ideal in applications where power is intermittent such as solar. The LiPo
battery can be fully recharged within 4 hours of system power being connected.
If the internal LiPo has been allowed to completely discharge; when power is first applied to the ORB, the
battery will go into a pre-charge mode where the battery is charged to a minimum level before the ORB
starts operating. Pre-charge mode is identified by a slow flash on the green LED with the orange LED off.
Internal protection circuits prevent damage to the LiPo battery in the event of a short circuit or due to
excessive discharge. A temperature monitoring circuit prevents the LiPo battery from being charged at
temperatures above 40°C. It is recommended that the LiPo battery be replaced after three years of use or
more regularly if the ORB routinely operates in a temperature range exceeding -10 to 70°C. The LiPo
battery should only be replaced by a Senquip replacement part and should only be installed by a suitably
trained technician.
LiPo battery voltage is monitored to a resolution of 100mV and can be reported on a periodic basis if
enabled.
3.3 Replaceable AA batteries
In remote applications, where only low frequency measurement is required, the ORB can be powered by
four AA batteries. Either 1.5V alkaline, 1.6V lithium or 3.6V lithium AA batteries can be used. To
maximise battery life, it is recommended that either 1.6V lithium batteries like those shown below or 3.6V
lithium batteries are used. Where high quality lithium batteries are used, the ORB can run off batteries
for up to 10 years in sleep mode. Battery life of 1 to 2 years should be expected in real applications where
the ORB has been configured for low power operation.
