Sleepy, a smart night lamp that helps falling asleep.
What is it?
Meet Sleepy, a smart night lamp that will help you fall asleep.
Sleepy has two main modes – a night lamp and its “sleep mode”.
Using an acceleration sensor, Sleepy detects the user’s breathing patterns and leads the user into a slower, calmer breathing rhythm that will allow the user to relax and fall asleep more easily.
Once turned on, the accelerometer sensor, located under the sheet, detects the body's movements and starts a learning process of the user’s breathing pattern.
After the pattern is established, Sleepy’s light turns from green to blue, and starts imitating the user’s breathing rhythm by projecting a soft halo light at the same pace.
The intensity of the light beam increases during exhalation and decreases during inhalation.
Once Sleepy successfully measured the user’s respiratory rate, the light gradually and seamlessly changes its pace and guides the user towards a frequency of 6 breaths per minute, which research shows is the optimal frequency for a slow breathing technique.

How does it work?
Sleepy is operating with an MPU6050 acceleration sensor that detects the user’s body movements and using those, concludes the breathing rhythm.
Sleepy initiates its program with a calibration process that lasts for 40 seconds and is marked using a decreasing green led light. During the calibrations process the program will determine the upper and lower bounds of the user’s breathing pattern and then will beat with a blue led light accordingly.
In case Sleepy will detect any unusual movements during this time, it will initiate an additional calibration process.
During this minute of following the user, the program will calculate the users respiratory rate and then Sleepy will transfer to an autonomic leading mode. This mode will start off with the personally calculated respiratory rate and for the next 14 minutes will gradually lower this rate.
