    Introduction

    MQ2 is one of the commonly used gas sensors in the MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon a change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of the gas can be detected.

    What is a Smoke Detector?

    As the name indicates, a smoke detector is a device used to detect the smoke in the surrounding.  It is a fire-protection device with sensor that automatically senses the presence of smoke as the indication of fire and raises alarm.

    Advantages of Smoke Detector

    Smoke detector alarms are important safety tools used for the detection of smoke and fires. It warns the occupants about the presence of smoke so that they can immediately leave the premises for safety.

    Real-Life Applications of Smoke Detectors

    Smoke detectors are used in homes, schools, offices, malls, hospitals, and other places to ensure it raises the alarm to avoid casualties in case there is a fire in the area.

    What is a Buzzer?

    Buzzer is an electrical device that raises an alarm for signaling. In this project we are using the buzzer so that when the sensor senses the presence of smoke around, the buzzer raises the alarm.

    What is Arduino?

    Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino is used worldwide by electronic makers, students, hobbyists, and others for various electronic projects ranging from simple everyday objects to scientific instruments.

    Building Guide

    Step 1: Circuitry of the Robot

    • Powering the components
    • Powering the smoke sensors
    • VCC to 5V
    • GND / to GND
    • Output to Analog pin A0.
    • Connecting the Buzzer
    • +ive pin to Digital pin 11
    • GND to GND

    connect-Smoke-detcctor-bot

    Step 2: Calibrating Smoke sensor

    • To calibrate the gas sensor, you can hold the gas sensor near the smoke/gas you want to detect and keep turning the potentiometer until the Red LED on the module starts glowing. Turn the screw clockwise to increase sensitivity or anticlockwise to decrease sensitivity.

    calibrating-smoke-sensor

    Step 3: Logic

    • If the sensor senses smoke, then the analog reading value will increase.
    • And if the reading value reaches the threshold value then the buzzer should turn on.

    Step 4: Code

    • Start by declaring the pins we are using.

    smoke-detector-code

    • Applying a conditional operation to turn on and off the buzzer.

    Introduction

    Radio frequency (RF) modules are the devices that operate on Radio Frequency. The frequency range varies between 30 kHz & 300 GHz. These small electronic devices are used to transmit and/or receive radio signals between two devices. Bluetooth devices available in the market are costly which is why long-range of wireless devices are used. 

    The transmitter and receiver are two main components of the RF modules. These operate at 434MHz. The frequency acts like a password between both transmitter and receiver. The circuit doesn’t work if the frequency between both the modules doesn’t match.

    After receiving the serial data from the encoder, the RF transmitter transmits it wirelessly. This transmission takes place at a rate of 1kbps–10kbps. The RF receiver then receives the transmitted data and then the decoder converts it into serial data.
