Evaluation Board Extends Lifetime Of Sensor Module


RECOM’s new breakout board connects SensiEDGE’s SensiBLE v1.0 sensor module to RECOM’s R-78S evaluation board. This enables engineers to consider an alternate power source (apart from a coin cell) for the SensiBLE sensor module and extend its lifetime. 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.

When powered by a coin cell, the module’s input voltage quickly drops below 2V after only a few hours of use. This prevents the Bluetooth functionality to operate properly and leaves the energy from the coin cell battery wasted. This can be averted by incorporating the functionality of the R-78S, which functions to boost a single-cell AA battery voltage of 1.5 V up to a stable 3.3 V.

This technology enables the SensiBLE to draw a stable 3.3V from an 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.


Test points for measuring voltages and currents make it possible to effortlessly calculate the typical battery life for the SensiBLE in both active and standby

The R-78S Evaluation Board and the corresponding breakout board are available at authorized distributors.
