 +The measured values are calibrated software-wise by calculating the average absolute error and subtract it from the measured value. Doing that the precision of the sensor could be improved as it can be seen in **Figure {{ref>temphumkurve}}**.

 Also bGuard mobile application is one of the things that need further development. The team had an idea of what the app should look like and what data it should provide but were only able to design the interface. The application is now merely a concept. Moreover, the team was not able to develop a real app in the given time. For example, now bGuard is limited to sending an audio file to the Smart Pillow but in the future, the team would like to expand this to a communication feature which allows the parents to talk to the baby.  Also bGuard mobile application is one of the things that need further development.

-Additionally, the tests can be improved. The pressure test simulation in SOLIDWORKS by taking into account the calculation of the force (based on the real weight of the home station including all the components) as also the pressure. Also, the tests of the sensors and their aim can be improved.+Additionally, the tests can be improved. The simulation in SOLIDWORKS by taking into account the calculation of the force (based on the real weight of the home station including all the components) as also the pressure. Now, the tests has been done with assumptions of real life examples.  Also, the tests of the sensors and their aim can be improved.
  
 Furthermore, the team would make our bGuard comply with the regulations of being a medical device. This would help to position the bGuard as a trustworthy device and help make bGuard to a market leader.   Furthermore, the team would make our bGuard comply with the regulations of being a medical device.
