RECOM Evaluation Board Extends Lifetime Of SensiBLE MODULE
RECOM has released a breakout board to connect SensiEDGE's
SensiBLE v1.0 sensor module to RECOM's R-78S evaluation board. This technology
enables the SensiBLE to draw a stable 3.3V from a AA battery down to voltages
as low as 0.65V. Engineers can therefore replace the coin-cell battery with a
higher-capacity single-cell AA battery and significantly increase operation
lifetime on a single battery.
RECOM's breakout board SBL-1 for the R-78S Evaluation Board
enables engineers to consider an alternate power source for the SensiBLE sensor
module whose input voltage from a coin cell quickly drops below 2V after only a
few hours of use. As a result of this, the transmission unit may be prevented
from operating properly and leaves the energy from the coin cell battery
wasted. This can be avoided by incorporating the functionality of the R-78S
which boosts a single-cell AA battery voltage of 1.5V up to a stable 3.3V "“
demonstrated by the R-78S Evaluation Board. Test points for measuring voltages
and currents make it possible to effortlessly calculate the typical battery
lifetime for the SensiBLE in both active and standby modes.
By considering this solution, the engineer can now replace
the SensiBLE's coin-cell battery with a higher-capacity single-cell AA battery.
Getting rid of the coin cell guarantees a much longer application lifetime and
at the same time reduces maintenance costs. There is also an option to use
external input voltage from other low voltage sources such as energy harvesting
devices which are typical in remote applications.
