Wireless Temperature monitoring system using Bluetooth

(Last Updated On: February 13, 2020)

Wireless temperature


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.

This project mainly focuses on how to request the Sensors data from the Arduino, this method is best as it never keeps the Arduino busy in sending the messages again and again. So whenever you need to check the temperature and humidity values, you simply send a request command to the Arduino Uno.
