🔌 Electronic Project Series – Project 6 LPG Gas Detection System using Raspberry Pi Pico and MQ-2 Sensor This project focuses on detecting the presence of combustible gases using an MQ-2 gas sensor and Raspberry Pi Pico. 💡 Objective: To understand gas sensing, sensor calibration, and threshold-based detection using MicroPython. ✅ Implementation: The MQ-2 sensor was interfaced with a Raspberry Pi Pico to monitor gas concentration levels. • When the sensor reading remained below the predefined threshold, the system displayed "NO GAS DETECTED". • When the sensor reading exceeded the threshold, the system displayed "GAS DETECTED" and activated the onboard LED as an alert. For demonstration purposes, agarbatti smoke was used to observe changes in sensor readings and verify the detection logic. 📸 The images show: • MicroPython code implementation • Real-time sensor readings and detection output • LED indication based on sensor threshold values 🔧 Components Used: ・Raspberry Pi Pico ・MQ-2 Gas Sensor ・BMP280 Sensor ・MicroPython ・USB Cable 📚 Key Learnings: • Working with the MQ-2 gas sensor library • Sensor calibration and threshold selection • Reading LPG-related values using MicroPython • Implementing alert systems using conditional logic • Interfacing sensors with Raspberry Pi Pico LMES Academy #Electronics #ECE #EmbeddedSystems #RaspberryPiPico #MicroPython #MQ2 #GasDetection #SensorInterfacing #EngineeringStudent #LearningInPublic
