IOT based Raspberry Pi Home Security System with Email Alert www.circuitsindia.blogspot.com IOT based Raspberry Pi Home Security Project with Email Alert In the world of  Internet of Things (IoT)  when we have all the technologies to revolutionize our life, it's a great idea to develop a system which can be controlled and monitored from anywhere.  There are many types of good security systems and cameras out there for home security but they are much expensive so today we will build a low cost simple  Raspberry Pi based Intruder Alert System , which not only alert you through an email but also sends the picture of Intruder when it detects any. In this  IoT based Project , we will build a  Home Security System using PIR Sensor and PI Camera . This system will detect the presence of Intruder and quickly alert the user by sending him a alert mail. This mail will also contain the Picture of the Intruder, captured by Pi camera. Raspberry Pi is used to con

Different Types of Sensors and their Working www.circuitsindia.blogspot.com Different Types of Sensors The era of automation has begun already. Most of the things that we use now can be automated. To design automated devices first we need to know about the sensors, these are the modules/devices which are helpful in making things done without human intervention. Even the mobiles or smartphones which we daily use will have some sensors like hall sensor, proximity sensor, accelerometer, touch screen, microphone etc. These sensor acts as eyes, ears, nose of any electrical equipment which senses the parameters in outside world and give readings to devices or Microcontroller. What is a sensor? The sensor can be defined as a device which can be used to sense/detect the physical quantity like force, pressure, strain, light etc and then convert it into desired output like the electrical signal to measure the applied physical quantity . In few cases, a sensor alo

Alexa Voice Controlled LED using Raspberry Pi and ESP12 www.circuitsindia.blogspot.com In previous tutorials we have seen  How we can build an Amazon Echo Speaker  and then  how can we control any Raspberry Pi GPIO using Alexa Voice . Now we are making an  IoT project  to  control home appliances from anywhere in the world using AlexaPi and ESP-12E  (or any ESP board). Hardware Requirements Raspberry Pi with AVS installed in it USB 2.0 mic /Webcam ESP-12E Relay module LED/AC bulb You should have your Raspberry Pi ready with Alexa voice service installed in it with a properly configured Amazon Developer Account. So go through below tutorial to get Alexa services ready. Build your own Amazon Echo using a Raspberry Pi Project Flow for Alexa Voice Controlled LED www.circuitsindia.blogspot.com We will follow this flowchart for this  IoT controlled LED project : So, the process is something like this. First, input is given to Raspberry Pi through the  USB  Mic
