BabyGuard will notify your phone or fix phone when a baby waked up.

It takes in a degree of leaning change of iPhone using an acceleration sensor.
And it makes an outgoing call to a registration phone number when it inclines too much.
You will hear the sound of your baby cry or not.

An acceleration sensor works after pushing the START button and throws away first 20 values.
It gets the average degree of leaning in next 20 values.
It starts monitoring with the degree of leaning as a standard degree of leaning level.
It stops monitoring one minute later and it restart at the start time and stops at the end time.
Greatly lower the brightness to reduce battery consumption.

During monitoring, It displays the X-axis Y-axis, the value of the Z-axis.
I think an acceleration sensor might not work definitely when the value is 0.000000.
Please try another iPhone.

An acceleration sensor find an incline when a baby stretching whole body.
If a baby touched iPhone, iPhone call you definitely.
