Inspiration

Inspiration areas/ideas include: -Education: Wearable device/ desktop app which sends notifications to take study breaks for higher productivity, maybe motion sensors

-Health & Well-being: Vibration sensors for shaking hands; focus on old people/physically challenged people; motion sensing; mice-detecting

-Sustainability: CO2 emission stuff; gas-leak detection; water-leak detection; sound-sensor; lights; temperature rise +buzzer; light+motion sensing; high temp → turn on AC; trash level detection Wanted to

What it does

-Detect level of trash in a trashcan -Measure frequency of trash input

-Show level and frequency of trash recycling on web server from UC campuses

How I built it

We utilized the Design Thinking approach to decide the idea and finalize prototype.

Step1: Empathize

We were inspired from the hackathon challenge areas and related with the areas. We were responding to the challenge from Northrup Grumman - Model Based System Engineering & IoT

Step 2: Define

Used creative techniques to create a communication hub for 2 or 3 sensors which can be controlled by an application on a central node within one day

Step 3: Ideate

• Study break → Timer? --> discarded
• Trash Can Level of trash Amount of trash Frequency of trash Gamify - competitive recycling/ gamifying / social elements, leaderboard - between friends, UC applications; comparison between trash & recycling; most popular spots on campus/cities

Decided to go with the idea of trash can

Step 4: Prototype

Tried integration sensors - temp, humidity, photoresistor, infrared, motion sensor, light Managed to achieve photoresistors, PIR + led , ultrasounnd sensor 2 approaches: one only with serial monitor; one with hosting to web server

Step 5: Test

Tested with button, photoresistor, PIR, ultrasound and infrared sensors

Challenges I ran into

ESP8266 stopped responding to code 1 Teammate deserted on 2nd day Trouble setting up database

Accomplishments that I'm proud of

Achievements -Able to detect trash input based on PIR motion sensor -Able to display if trash can is open/closed based on light intensity from photoresistor -Working on detecting trash level in a can using ultrasound sensor

Proud of -Staying up all night & still having energy to move forward

What I learned

-Integrating sensors -ESP8266 -Java script -node.js

What's next for yourTA

-Alert when recycling is thrown into trash and vice versa -use cameras to detect (type) trash and detect type and amount of waste -Real-time trash level status across UC campuses
