Wireless temperature Monitoring Project Description:

Wireless Temperature Monitoring- This tutorial is based on the wireless Temperature monitoring using Bluetooth module, Arduino Uno and Android cell phone application. In this project, the temperature request can be sent to the Arduino at any time. This project also has a feedback system. The command is sent wirelessly to the Arduino Uno, the Arduino once receive the command then replay back with the temperature and humidity values. In this project, the famous DHT11 temperature and humidity module are used for monitoring the temperature and humidity.

DHT11 Temperature and Humidity sensor:

The DHT11 Temperature and Humidity Module is one of the most commonly used sensors. The DHT11 sensor most frequently is used in Weather Station projects. The DHT11 Temperature and Humidity Sensor has a total of 4 pins. Out of these 4 pins, we will use only three pins. Pin number 3 will not be used.
