MICROCONTROLLER BASED AUTOMATIC DOOR OPENING AND LIQUID PETROLEUM GAS DETECTING SYSTEM
Abstract
- The purpose of the current research is to construct “Automatic Door Opening and Liquid Petroleum Gas Detecting System”. The design is based on an Arduino Uno board, PIR (passive infrared) motion sensor, L298N motor driver, CD tray with 5V DC motor, Gas sensor MQ3, 0.96 I2C LCD driver and jumper wires. The PIR sensor is used to open and close the door automatically. The MQ3 sensor is used as liquid petroleum gas detecting system because it is suitable for detecting alcohol, benzine, CH4, hexane, LPG and CO. The Arduino UNO board is used to control all sensors’ operation and gives an output. The controlled program is written in C programming language. The system can also be expanded with an inductive detector for metal detection purpose of security.
