Smart Sensors

Course introduction

Students connect environmental sensors to the ESP32 and build smart systems that act on the data.

About this course

Builds a weather station (DHT11), a fire alarm (flame sensor), a gas-leak detector (MQ-2) and a smart parking system (ultrasonic + servo), with safe 3.3V wiring throughout.

ESP32 එකට පරිසරය දකින sensors — Weather Station, Fire Alarm, Gas Detector, Smart Parking.

What you'll learn

• Read DHT11 temperature/humidity
• Detect flame and gas safely
• Use servo + ultrasonic together
• Wire sensors for 3.3V logic

Lesson plan

1. Project: Weather Station (DHT11) — Read and display temperature and humidity.
2. Project: Fire Alarm (Flame Sensor) — Detect flame and raise an alarm.
3. Project: Gas Leak Detector (MQ-2) — Detect gas with an MQ-2 sensor.
4. Project: Smart Parking System (Ultrasonic + Servo) — Automate a parking gate.
