We are using Arduino Uno, so for that we have to use Arduino IDE. Here is the link for Arduino IDE. Also, we are getting data in our smartphones, so for that we are using Bluetooth Terminal App.
Hardware RequiredThese are the hardware components we are using:
- Arduino Uno
- DHT22 sensor
- HC-05 Bluetooth Module
- Jumper wires
- 10k resistor
Here we are using DHT22 for which you have to include DHT22 library in our Arduino IDE. You can download it from the link below.
You can include this library using one of two methods:
1. Open to the Arduino IDE and go to Sketch tab. Then go to Include Library and select option Add .ZIP Library as shown in the figure:
2. Download this library folder, unzip it and then copy it into the library of your Arduino Software.
Project DescriptionYou can see the circuit diagram in these figures.
How this project will work:
Download the code given in the next step and upload it to the Arduino Uno.
And then make the connection as shown in the circuit diagram. Make sure you have to unplug your jumpers from RXD and TXD of your HC-05 module before uploading the code to Arduino Uno.
Now you have to download the Bluetooth Terminal App in your smartphone. Then you have to pair it with HC-05 module. If you successfully pair your samrtphone with HC-05, you will see the Temperature and Humidity data coming from DHT22 sensor.
