Aim

To design an IoT system that solves a real-life social or community problem.

Requirements

• Chart paper / whiteboard / notebook

• Colored pens / markers

• Optional: Arduino Uno, sensors, IoT dashboard (for digital prototype)

Steps

Step 1: Pick a Social Problem

• Examples to inspire students:
  • Water wastage in schools or farms

  • Elderly people needing emergency help

  • Streetlights left ON during daytime (energy waste)

  • Air pollution monitoring in cities

• Students choose one real problem they care about.

Step 2: Brainstorm IoT Solution

• Ask: “How can IoT help?”

• Example:
  • Problem: Farmers waste water while irrigating.

  • IoT Solution: Soil moisture sensor + pump + mobile app → pump ON only when soil is dry.

Step 3: Plan the System

• Draw a simple IoT cycle:
  • Sensor → detects condition (soil dryness, temperature, motion).

  • Device → acts (turns ON pump, sends alarm, switches OFF light).

  • Internet/App → allows remote control or monitoring.

Step 4: Create a Prototype (Optional)

• Use chart paper to draw your system and label components.

• OR use Tinkercad/Blynk to simulate.

• Example drawing: sensor in soil → Arduino → Wi-Fi → mobile app → pump ON/OFF.

Step 5: Present Your Idea

• Students present their solution in class or small groups.

• They explain:
  • What problem it solves

  • How the IoT system works

  • Benefits for people/community
