Children's Safety Habit Builder
Freya Yu 2372732
Overview
- The project includes wearable sensors paired with a fixed-spot sensor to detect distance between children's hand and dangerous place, using light and sound to trigger children's discomfort to caltivate children's habit to not touch dangerous places.
- Targeted children age: 1-2 year old
Above is a general sketch of the project, highlighting the physical features.
Sensor Device
The sensor system contains one wearable sensor paired with multiple fixed-spot sensors around home environemnt to detect distance between children's hand and dangerous place.
- Clip form to easy attach to children's clothes
- in pair with the embedded sensor on display device (multiple location)
- possible selections: ToF sensor OPT3101, RF sensor RF430FRL15xH
- processor: XIAO ESP32S3
Above: Detailed Sensor Device Sketch
Display Device
The purpose of display design is to use beeping sound and red led blinking to make children (under 2 years) uncomfortable and quit action
- gauge indicating the extent of danger
- turn off switch button
- warning leds
- embedded speaker
- Battery: Chargeable battery, button or AAA size

Questions
How big is the Adafruit MPU6050 PCB?
It measures 25.4 × 17.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Adafruit MPU6050 use?
28 parts, built around the AP2112K-3.3, MPU-6050 and BSS138. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Adafruit MPU6050 KiCad files?
From the yeyfreya/TECHIN514-Final-Project repository on GitHub, at the commit this page was made from: the board is Schematics/Adafruit-MPU6050-PCB-master/Adafruit MPU6050/Adafruit MPU6050.kicad_pcb and its schematic Datasheet/No Use This Time/TSL2561-breakout-board-PCB-master/TSL2561_v0.1_1/TSL2561_5V_REV-A/TSL2561_5V_REV-A.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adafruit MPU6050 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
