Intruder Detection via SMS (Twilio) using Arduino, PIR & Ethernet Shield

Arduino is the most common open source hardware for implementing cool projects, and PIR is most widely used to detect motion and human presence. More details on how to interface Arduino with PIR. Today we would explain you a step-by-step guide on how you can build intruder detection system using Arduino and receive an alert via SMS. Things you need: Arduino (2560 Mega recommended) Ethernet Shield compatible with Arduino. More details here. Motion Sensor PIR. Internet access to your Arduino First of all, you need to connect your Arduino with Ethernet Shield and check if its working properly. If you are...

Arduino Interfacing with PIR Motion Sensor

Pir Sensor is most common to detect motion of Passive Infrared radiations that are emitted by Humans/Living things. These radiations are invisible to the human eye but are not to Fresnel lens which enhances the radiations onto PIR detector. The IR sensor itself is housed in a hermetically sealed metal can to improve noise/temperature/humidity immunity. There is a window made of an IR-transmissive material (typically coated silicon since that is very easy to come by) that protects the sensing element. Behind the window are the two balanced sensors. As shown below: PIR sensor itself creates a small millivolt when...

Monitor Room Temperature on Windows Phone App using Arduino

This article will help you implement a simple project that will require limited hardware and you can develop an app that can monitor your room or home temperature using Windows Phone. The major focus of this article is to help you develop a Windows Phone app using Windows Phone SDK ver 8.0 First of all, you need few things to implement this: Things you need: Arduino Board (Preferably Arduino Mega 2560) Ethernet Shield (This is plug n play shield that can be stacked on Arduino 2560) More details: Arduino Ethernet Shields LM35 Temperature Sensor A Windows Phone  Connecting Wires /...

Interface Arduino with Ethernet Shield & Display Temperature using LM35 on Web Browser

Previously we have introduced on how to interface LM35 using Arduino Mega 2560. In this article, we will show you how to interface Ethernet Shield with Arduino 2560 and display temperature data using LM35 on your Web Browser. See How to Interface LM35 using Arduino Mega 2560 To implement this project you need the following things: Arduino Board (any board will do the trick, but we recommend buying Mega2560 as we will be using this board for more projects) More details can be found here: Arduino Boards Ethernet Shield for Arduino. More details can be found here: Arduino Ethernet...

LM35 Interfacing with Arduino Mega 2560

Arduino has been around since 2005 and it is one of the most popular cheap DIY (Do it Yourself) board available in the market. It is a single board complex circuit which has a microcontroller, reset switch, USB port for PC interfacing (serial communication) and input/output ports etc. The board has an open source hardware board designed for 8 bit Atmel AVR microcontroller or 32 bit Atmel Arm. Now a day’s Arduino has USB interface having six analog input pins and 14 digital input/output pins; earlier it had VGA port for interfacing with a computer. We can attach other kits and shield...
