About the Project
GASTECH is an IoT-based LPG gas level monitoring system designed to provide real-time visibility into cylinder usage and help users avoid unexpected gas shortages.
Problem Statement
Conventional LPG cylinders do not provide any mechanism to indicate the remaining gas level. Users are forced to rely on manual methods or assumptions, which often leads to sudden gas depletion during critical usage times. This results in inconvenience, safety concerns, and inefficient gas management.
Proposed Solution
The proposed system continuously measures the weight of the LPG cylinder using a load cell. The sensed data is amplified through an HX711 module and processed by an ESP32 microcontroller. The system computes the gas percentage and uploads it to a cloud-based Firebase Realtime Database. A web application retrieves this data in real time to display gas levels, usage trends, and estimated days remaining.
System Implementation
- Weight sensing using strain gauge load cell
- Signal amplification using HX711 ADC
- ESP32 for computation and Wi-Fi connectivity
- Firebase Realtime Database for cloud storage
- Web-based dashboard for visualization and analytics
