- Propose a final project masterpiece that integrates the range of units covered, answering: - What will it do? - Who's done what beforehand? - What will you design? - What materials and components will be used? - Where will come from? - How much will they cost? - What parts and systems will be made? - What processes will be used? - What questions need to be answered? - How will it be evaluated?
What will it do?
My final project is called * I CAN SENSOR YOU *. It is a night lamp that has a temperature and humidity sensor on it. Then a microphone and an OLED display. Temperature and humidity sensors will monitor the change in ambient temperature and humidity. The microphone will "listen" the sounds in the environment ie the breathing of the sleeping person. Temperature and humidity data will be displayed on the OLED display. In the event that the level of "noise" ie sounds produced by a sleeping person and his environment falls below a certain parameter, an alarm is sent - a signal to the mobile phone. The lamp is connected by a wifi module to the mobile phone of the person supervising the person who has a sleep problem.
Who's done what beforehand?
Since the diagnosis is sleep apnea plus the primary diagnosis of DS for my son,
that means - a big problem, because it can all cause a heart attack, stroke, etc.
After the diagnosis, I started researching the diagnosis itself, but also help.
Sleep disorder - light Obstructive-sleep-apnea#risk-factors Philips - smartsleep Assistance is in the form of operations that are not currently being performed due to COVID. The next choice was technology.
What will you design?
I will design the lamp completely: - the stand, the base where the sensors are located, the motor, and the PCB board, - the rotating mushroom-shaped part made of lamellae, - the upper part where the LEDs are located. Then I will design: - PCB board with which I will control the sensors and an application that monitors the operation of the sensors and informs about the parameters.
What materials and components will be used?
I will use: - PLA filament 2,85 mm, dark blue, for parts printed on a 3D printer - Plexiglass -3 mm for laser cut parts - Microphone Sensor High Sensitivity Sound Detection Module For Arduino - Mitsumi M35SP-9T Stepping Motor - Arduino Digital Temperature/Relative Humidity Sensor DHT11 Module - Geekcreit® 0.96 Inch 4Pin Blue Yellow IIC I2C OLED Display Module - DC3.7V 3W 80x7.5mm COB LED Strip Bar Light Warm Cold White - MCU AVR 8-Bit 16KB Prog SOIC-14 - AZDelivery esp8266 ESP-01S WiFi Parent module - PCB: don’t know yet the summary of the components for my PCB so this one is going to be described on my Final project(link) site
Where will come from?
I will procure the parts I need from: - marwiol.pl - ebay - Banggood - Amazon and - local stores.
How much will they cost?
- PLA filament 2,85 mm, dark blue - kg €16,50- 0,3 - €4,95 - Microphone Sensor High Sensitivity Sound Detection Module For Arduino - pcs €1,78 -1- €1,78 - Mitsumi M35SP-9T Stepping Motor - pcs €7,00 - 1 - €7,00 - Plexiglass - €28 m2 - 0.3 m2 - € 8.4 - Arduino Digital Temperature/Relative Humidity Sensor DHT11 Module - pcs €1,17 -1- €1,17 - Geekcreit® 0.96 Inch 4Pin Blue Yellow IIC I2C OLED Display Module - pcs €6,13 -1- €6,13 - DC3.7V 3W 80x7.5mm COB LED Strip Bar Light Warm Cold White - pcs €2,54 - 2 -€5,08 - MCU AVR 8-Bit 16KB Prog SOIC-14 - pcs €0,60 - 1 - €0,60 - AZDelivery esp8266 ESP-01S WiFi Parent module - pcs €3,33 - 1 - €3,33 - PCB: don’t know yet the summary cost of the components for my PCB so this one is going to be described on my Final project(link) site - Total - around - €40
What parts and systems will be made?
- Housing for electronics, electronics - Lamp base, rotating bracket, LED holders will be printed on a 3D printer, lamp lamellas will be made of Plexiglas and cut with a laser cutter
What processes will be used?
To create my project I used: - to design parts to be cut and printed - Onshape program - I used SketchUp Pro 2021 with addons to make the upper part of the lamp - I used the Ultimaker 3D printer and the Ultimaker Cura program to make 3D parts - I used KiCad to make a schematic representation of the PCB board - I will use a Roland MDX-15 CNC milling machine to make the PCB board - The chip is programmed using Arduino IDE. - I will use Arduino IDE and Blynk application on my mobile phone to create a mobile application.
What questions need to be answered?
Questions I still need to answer: - will the lamp be stable enough ? - will I successfully solder and program all components on the PCB board? - Will I successfully connect the lamp and mobile phone?
How will it be evaluated?
I think that my lamp should be evaluated depending on the success of reading the temperature and humidity in the room and the display on the oled display, reading the noise level - or the absence of the same . The lamp should be able to rotate in one direction after turned on / off from the switch.
