PROJECT:
Creation of a device for monitoring movements during sleep, without contact with the user (embedded system), with the aim, for example, of providing data indicating the presence of some pathology, such as disturbance of periodic limb movements and the restless legs syndrome. As a main electronic component, a microwave motion sensor was used, your signals are received during sleep, processed and displayed on the LCD.
STEPS:
- Construction of the schematic circuit for the microwave sensor (HB100) and processing of its signal;
- Construction of the schematic circuit for the remaining monitoring device. For this, an Arduino, a clock (RTC DS1307), a humidity and temperature sensor (DHT11), an LCD (Nokia 5110), a buzzer, a bluetooth module were used and a power supply;
- Arduino programming, in C ++, for signal processing and the appropriate response;
- Development of a prototype case to protect the entire circuit.
SCHEMATIC CIRCUIT:
FILES:
- sleep_quality.ino - code with all the functionalities of the implemented device necessary to create an embedded system, using the Arduino microcontroller.
- Suporte.ipt - Solidworks file with the drawing of the box of the case prototype.
- Encaixe.ipt - Solidworks file with the drawing of the cover of the case prototype.
- Suporte_proto.ipt - Solidworks file with the drawing of the supports for the electronic circuit inside the case prototype.
