Initialize DHT sensor for normal 16mhz ArduinoĬhar inchar // Will hold the incoming character from the GSM shield Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor Connect pin 4 (on the right) of the sensor to GROUND Connect pin 2 of the sensor to whatever your DHTPIN is NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1 Connect pin 1 (on the left) of the sensor to +5V Uncomment whatever the type of sensor we are using. #define DHTPIN 12 // what pin we're connected to

This way I can use the Arduino’s default Serial Port only for debugging purposes. In this project, instead of using the Arduino’s default Serial Port, I will be defining another Serial Port using the SoftwareSerial library.

The TX pin of the Bluetooth module is connected with Pin 7 of the Arduino Board, while the Power supply pins are connected with the Arduino’s power supply.Īndroid cell phone Apk file: BlueserialApp Wireless Temperature Monitoring Arduino Programming:īefore, you start the programming, first of all, make sure you download the DHT library. The RX pin of the Bluetooth module is connected with the Arduino’s pin number 8. The Bluetooth module HC-05 or HC-06 is connected with the Arduino’s pins 7 and 8. While the power supply pins are connected with the Arduino’s 5V and GND pins. The data pin of the DHT11 sensor is connected with the Arduino’s digital pin 12. Wireless Temperature monitoring Circuit Diagram: Out of these 4 pins, we will use only three pins. The DHT11 Temperature and Humidity Sensor has a total of 4 pins. The DHT11 sensor most frequently is used in Weather Station projects. The DHT11 Temperature and Humidity Module is one of the most commonly used sensors. I would appreciate your support in this way! I may make a commission if you buy the components through these links. So whenever you need to check the temperature and humidity values, you simply send a request command to the Arduino Uno.įor the complete step by step explanation, you can watch a video Tutorial given at the end of this article.

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. In this project, the famous DHT11 temperature and humidity module are used for monitoring the temperature and humidity. 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 temperature request can be sent to the Arduino at any time. Wireless Temperature Monitoring- This tutorial is based on the wireless Temperature monitoring using Bluetooth module, Arduino Uno and Android cell phone application.
