PlantMoji
An edutech kit that turns raw sensor data into a plant emotion, so beginners learn smart farming by reacting to something alive.
Three ideas went into screening
LDR + DHT close the roof and sound a buzzer.
Sponges and sensors simulate a whole crop climate.
Button or ultrasonic sensor guards pedestrians.
One idea scored far above the rest

What PlantMoji is
Purpose, method, and the feature that makes it stick.
An edutech kit with a gamified dashboard
Sponges and sensors mimic Jember crop environments, so learners set up growing conditions in minutes instead of waiting weeks.
A quest-based web interface turns sensor readings into XP, levels, and daily missions.
Sensor data becomes a plant emotion
Hover a state to see how the kit reacts.
Happy
Light, humidity, and soil are all in range.
Normal
One value drifts; the kit nudges the learner.
Sad
Conditions break; a quest asks for a fix.
Sensor to dashboard in one data pipeline
Soil · DHT11 · LDR
Reads and filters
Routes the stream
Mood, XP, quests
How we build it
The IDDOV cycle, from problem to demo.
Five phases, one deliverable each
Identify
Find the learning gap in plant monitoring.
Define
Lock hardware, software, and content specs.
Develop
Assemble and code the working prototype.
Optimize
Tune sensors and prevent malfunctions.
Verify
Review as a user, finalize the demo.

Total labor (Rp)
All five phases
Seven hours already on the board
- JUL 31 · 6 people · 2h
Inspected Arduino modules, brainstormed topics with post-its.
- AUG 02 · 7 people · 2h
Organized brainstorm results and narrowed the candidates.
- AUG 05 · 7 people · 3h
Built the basic Arduino structure and finalized the topic.
Risks and the team
What could slow us down, and who carries what.
Two risks we already answered
Less than 12 days
We exclude the real plant-raising process and focus on condition setting, prioritising MVP features.
New ML and TL join
Progress is delivered live through Discord, with responsibilities assigned by expertise.
Everyone knows their lane
Holds daily focus to prevent mess-ups
Settles the whole database quickly
Heavy load, but shared across three TLs
Owns the design side of the project
What the team does this week
- 01
Write sensor instructions
Light, humidity, and soil moisture, plus what each sensor does.
- 02
LCD shows plant feelings
Map sensor thresholds to Happy, Normal, and Sad states.
- 03
Build the Node-RED flow
Wire the Arduino IDE side into the web dashboard.
- 04
Close the Define phase
So Develop starts on schedule with locked specs.
