Sensor Charge Modes
Sensor devices have four charge modes based on the current charge capacity of
the device’s battery. The four modes are
• Always On mode, when the battery is at 100%;
• Fast mode, when the battery is above 76.7% but below 100%;
• Slow mode, when the battery is at or below 76.7% but above 0%;
• Always Off mode, when the battery is fully discharged.
The device stays on continually in Always On mode which usually occurs on
sunny days when the solar panels can power the device and keep the battery
fully charged. In Fast mode the device “wakes up” every 10 seconds to see if it
is being interrogated. In Slow mode the device only wakes up every 2 minutes.
If the battery becomes fully discharged, then the device shuts off completely.
