Arduino Image processing CCTV camera system application designing and programming
Description: Arduino Image processing –In this tutorial you will learn how to use image processing, Arduino Uno and PIR sensor to create your own Arduino based CCTV camera device. “Visual Basic” will be used to create the image processing program in this tutorial vb.net.This application works in conjunction with the Arduino Uno connected PIR sensor. Once both the PIR sensor and the image processing application detect the human, a picture is automatically captured and stored in a folder. Visual Basic.net will be used for the image processing software. It’s really easy to model image processing applications in vb.net. The Frontal face XML archive is used in this application for human identification.Once the computer application detects the human face and also receives a signal from the Arduino, a picture will be taken automatically and stored in the desired folder. The Amazon Purchase links are given below: Pir motion sensor:…

Request Temperature Data Using GSM and Arduino programming
Description: This tutorial is based on monitoring temperature and humidity using a cell phone, Arduino and the well-known temperature and humidity sensor DHT11. In this project, we will learn how to use your cell phone to measure temperature and humidity from anywhere in the world. There are projects where the data from the Sensors is sent after regular intervals, which I don’t think is good. This project differs from the rest of the GSM-based projects, as the temperature and humidity values are only sent in this project when the owner sends a request message. The Amazon Purchase links are given below: dht11 sensor: https://amzn.to/2sPejzO GSM…
