Gas Leakage Detector using Arduino and GSM Module with SMS Alert and Sound Alarm

jojo December 23, 2016 64 Comments
We have published lots of interesting arduino projects like GSM based Fire Alarm System , Line Following Robot, RFID Based Access Control System and many other useful projects. This time, we are publishing a highly useful home application – Gas Leakage Detector using Arduino and GSM Module with SMS Alert and Sound Alarm.  We have published an LPG  Sensor Project using Arduino and MQ2 sensor before – which senses lpg leak and produces sound alarm. The project also has...

Interfacing MQ5 LPG Sensor to Arduino

jojo February 23, 2016 3 Comments
In this guide, we learn how to interface MQ5 Gas sensor (which is a generic Gas Sensor more suited to detect and determine LPG concentrations) with Arduino. In this tutorial, we are using the MQ5 Gas sensor module (which is widely available in market) . This module has two output possibilities – an analog out (A0) and a digital out (D0). The analog out can be used to detect Gas leakage and to measure volume of Gas leakage (by...

GSM based SMS Alert Fire Alarm System using Arduino

jojo August 10, 2016 104 Comments
In this article,we are going to build a Fire Alarm System using Arduino, LM35 Temperature Sensor and GSM Module. The objectives of this fire detector using arduino is to sense the surroundings for occurrence of fire with help of LM35 temperature sensor, and send 3 SMS alerts to two mobile numbers stored inside the arduino program if fire is detected (using GSM Module). We have developed a very good tutorial on how to interface GSM Module with Arduino and send/receive...

Simple RFID based Door Lock using Arduino

jojo April 7, 2015 6 Comments
Its quiet fun to work with RFID based projects! In the previous article, we saw how to interface RFID with Arduino. Interfacing is the first step to create any useful project. So why don’t we create an RFID based Access Control System or an RFID based Door Lock using Arduino? The system I have designed here is a simple version of the project. This project can be enhanced with a lot of features (which I will be doing in...

Interfacing RFID with Arduino – How to Read RFID Cards using Arduino

jojo March 26, 2015 15 Comments
In this tutorial, we are dealing with yet another interfacing technique. This time we are interfacing an RFID Reader which can read RFID Tags to Arduino. RFID is Radio Frequency Identification. An RFID reader is used to read RFID tags (which contain certain unique data stored in a chip). An RFID reader and an RFID tag, both have a coil surrounding them.  When an RFID tag is shown near an RFID Reader, it collects the unique tag data (a...

How to Interface GSM Module to Arduino-Send and Receive SMS

jojo August 11, 2018 171 Comments
In this article, we are going to see how to interface GSM Module to Arduino. There are different kinds of GSM modules available in market. We are using the most popular module based on Simcom SIM900 and Arduino Uno for this tutorial. Interfacing a GSM module to Arduino is pretty simple. You only need to make 3 connections between the gsm module and arduino. So lets get to business! A GSM Module is basically a GSM Modem  (like SIM...

Interfacing SPD005G pressure sensor to arduino This article is about interfacing pressure sensor to Arduino. The pressure sensor used here is SPD005G from Smartec . SPD (Smart Pressure Device) is a series of silicon based pressure sensors suitable for industrial as well as house hold applications. These sensors are generally available in plastic inline or dual inline packaging. SPD sensors are generally available in two operation modes namely gauge type and absolute type. In gauge type, the pressure is...

Digital Code Lock using Arduino with LCD Display and User Defined Password

praveen December 5, 2014 39 Comments
We have published a digital code lock using arduino some weeks before. This one is a little different. The earlier version was based on a defined password, where the user can not change it. Moreover there was no LCD display interfaced with the project to output lock status. This project is a much improved version of the same digital code lock which comes with a user defined password and LCD display. The user will be prompted to set a...

Interfacing gyroscope to arduino

praveen December 9, 2014 3 Comments
Interfacing gyroscope to arduino uno. This article is about interfacing gyroscope to arduino. Gyroscope is a device used for measuring the angular velocity in the three axes. It works under the concepts of angular momentum and can be used to determine the orientation of an object. Typical applications of gyroscope includes missile guidance, flight control, smart phones, game station joy sticks etc. Mechanical gyroscopes, MEMS gyroscope, optic fiber gyroscope, ring laser gyroscope. Here we deal with the MEMS gyroscope....
