Powering up the system
Both the smart monitoring station (STEVAL-IFS014V1) and smart monitoring node
(STEVAL-IFS015V1) can be powered up using the USB power adaptor (5 V, 500 mA) or the
mini USB cable (through a computer/laptop) or by using the battery (3.7 V Li-ion). The
system uses the battery power only in case of unavailability of the external power supply.
The system itself switches from the external power supply to battery and vice versa.
The system also has the capability to charge the battery when the external power supply is
available at which time the system switches its power consumption from battery to mains
and the battery starts charging.
On both the smart monitoring station and smart monitoring node, there is a power switch
which is used to switch the supply on or off to the system.
There are two status LEDs:
●
Power LED (PW): This indicates if the system is on or off
●
Charging LED (CH): This indicates the charging status of the battery. If the battery is
being charged from the external power supply, then this LED glows. If the external
power supply is available but the battery is fully charged, then this LED is off.
Note:
If no battery is connected and the system is powered using the USB supply, then the
behavior of the charging LED 'CH' is unpredictable.
Note:
For information regarding battery insertion in the STEVAL-IFS014V1 and STEVAL-
IFS015V1, please see
