Request Temperature

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.
