Gas Leakage Detector with gsm

In this tutorial we will learn how to make a GAS LEAKAGE DETECTOR to protect your home from a big explosion USE OF THIS CIRCUIT This is very usefull circuit to protect your home from a big explosion because when the gas leaks the sensor used in this circuit recognise it and make sound (if you are using buzzer) THINGS NEEDED * Arduino : https://amzn.to/40m7UpN * Gas Sensor (I am using MQ-6 Gas Sensor) : https://amzn.to/41n8Co2 *LED or Buzzer * GSM900a : https://amzn.to/43Bs5Tg CIRCUIT Gas Sensor : VCC to VCC GND to GND A0 to A0 LED : Positive to Pin13 Negative to GND GSM900a : 5vt to D9 5vr to D10 Negative to GND CODE ///https://dreamprojectsnow.blogspot.com/ //DREAM PROJECT MALAYALAM #include #include < SoftwareSerial . h > SoftwareSerial mySerial(9,

Smart Contactless DoorBell

Smart Contactless DoorBell Introduction Here we are showing how to make a Smart Contactless DoorBell .Smart doorbell systems are available in market but they are really costly.But is very simple to make at very low cost .So lets get started. Components Needed * Arduino x 1 * Ultrasonic Sensor x 1 * Buzzer x 1 (you can also use normal door bell which can be controlled with a relay. ) Circuit and Connection here we connected the ultrasonic sensor * VCC to 5V * GND to GND * Trig to D13 * Echo to D12 and we connected the buzzer * Positive to D11 and Negative to GND Arduino Code First we want to install arduino ide app ,Then copy the below code and paste it in the software and then click on the upload button . // full documentation in https://dreamprojectsnow.blogspot.com/ // also visit our youtube channel https://youtu.be/I6nCexr3RSI #define trigPin 13 #define echoPin 12 #define led 11 void setup() { Serial.begin (9600); pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT)
