Understanding the Components
The Arduino microprocessor is a powerful tool for physical computing and the Internet of Things. It is a programmable microcontroller that can be used to control various devices and sensors. The jumper wires are used to connect the Arduino board to the other components. The dht11 temperature and humidity sensor is a digital sensor that can measure the temperature and humidity in the atmosphere around us. It has three pins: VCC, data, and ground. The VCC pin is connected to the 5V pin on the Arduino board, the data pin is connected to the digital pin 8 on the Arduino board, and the ground pin is connected to the ground pin on the Arduino board.
Setting Up the Circuit
Once all the components are connected, the circuit is ready to be tested. To test the circuit, we need to upload the code to the Arduino board. The code is written in the Arduino IDE and can be downloaded from the Arduino website. The code is written in C++ and is very simple to understand. Once the code is uploaded to the Arduino board, the circuit is ready to be tested.
Testing the Circuit
Once the circuit is set up, we can test it by connecting the Arduino board to the computer. Once the connection is established, we can open the serial monitor in the Arduino IDE and check the temperature and humidity readings. The readings should be accurate and consistent. If the readings are not accurate, then we can adjust the code accordingly.
Connecting the Wires
The first step in creating the Hot and Humid App is to connect the jumper wires to the PIN in the dhd1 Music sensor. This is done by connecting the wires one by one to the Arduino board. Once the connections are made, the Arduino is then connected to the computer using the Music cable.
Creating the Project
The next step is to create the project in M blocks. To do this, users must first sign into their account and open a new project. It is recommended that the project be renamed to “Hot and Humid” and saved before connecting the device. After the project is created, a background and sprites can be added to the object.
Connecting the Arduino
Once the project is created, the Arduino must be connected to it. This is done by going to the devices tab, clicking the add button, and selecting the Arduino Uno from the list. After the device is connected, an extension must be added to the project. This is done by searching for the “Upload Broadcast Mode” extension and adding it to the project.
Coding the Project
The final step in creating the Hot and Humid App is to code the project. This is done by adding blocks to the project and programming the Arduino to read the temperature and humidity data. Once the code is written, it can be uploaded to the Arduino and the app can be tested.
I bring the when upload message received block and change the message to temperature. Then I will bring a set text to block and drag it here and set the text to temperature is and then I will bring a join block and add it here.
Adding the Sensors Extension
The first step in creating the Hot and Humid App is to add the Sensors extension to the Music project. This is done by clicking on the Extensions tab and searching for Sensors. The VN NDA extension is then added, which allows the DHT sensor to be added to the project. The corresponding code in C language is then generated, providing an opportunity to learn coding in C language.
Continuously Measuring Temperature and Humidity
The next step is to ensure that the temperature and humidity can be continuously measured. To do this, a Forever block is added and the weight time is set to 0.25 seconds. A Send Upload Message with Value block is then added, with the message set to temperature. The Read: Temperature block is then changed to pin 8. The same process is repeated for the humidity, with the message set to humidity and the Read: Humidity block changed to pin 8.
Coding the Panda Sprite
The Panda Sprite is then coded to tell the temperature. To do this, the Upload Broadcast Mode extension is added to the Sprite tab. The When Upload Message Received block is then added, with the message set to temperature. A Set Text to block is then added and the text is set to “Temperature is”. A Join block is then added to complete the coding.
Creating the Variables
In order to store the temperature and humidity values, two variables need to be created. The first variable is for temperature and the second variable is for humidity. To create the variables, the Variables tab needs to be accessed. Once the tab is opened, a new variable can be created and named accordingly. The temperature variable should be named temperature and the humidity variable should be named humidity.
Coding the Sprites
After creating the variables, the next step is to code the Sprites. In order to do this, the Upload Mode Broadcast tab needs to be accessed. Here, the event for receiving the upload mode message needs to be brought. The message should then be changed to either temperature or humidity depending on the variable that needs to be set. The Panda Sprite should be used to tell the temperature and the Bear Sprite should be used to tell the humidity. To do this, a Say Music block needs to be used.
Uploading the Code
Once the code has been written, it needs to be uploaded to the Arduino processor. To do this, the Devices tab needs to be accessed. Here, the Upload Music button needs to be clicked. This will upload the code to the processor.
Testing the Project
The project can now be tested to ensure that it is working correctly. The Panda Sprite should tell the temperature in degrees Celsius and the Bear Sprite should tell the humidity in percentages. The values will vary depending on where the project is located. For example, if the project is located in Mumbai, the humidity should be 67.7%.
Exploring Temperature and Humidity with the Hot and Humid App
The Hot and Humid App is an exciting project that allows users to measure the temperature and humidity in different locations. With the help of a dstd sensor, users can observe the changes in temperature and humidity in different areas. This project is an excellent way to explore the environment and to gain a better understanding of the climate.
The Dstd Sensor
The dstd sensor is the key component of the Hot and Humid App. This sensor is responsible for collecting data on temperature and humidity. It is a small device that can be moved to different locations to measure the temperature and humidity in that area. The data collected by the sensor is then displayed on the app.
Observing Changes in Temperature and Humidity
The Hot and Humid App allows users to observe changes in temperature and humidity in different locations. For example, the temperature may be higher inside the house but lower in the balcony. Similarly, the humidity may be higher in the morning but lower in the evening. By observing these changes, users can gain a better understanding of the climate in their area.
Measuring Light Intensity
In the next episode, users will be able to measure light intensity using a photo resistor. This will allow users to explore the environment even further. With the help of this project, users can gain a better understanding of the climate and their surroundings.
In this episode of the series, we have learnt how to measure the temperature and humidity in the atmosphere around us using the dht11 temperature and humidity sensor. We have also learnt how to set up the circuit and how to test it. With this knowledge, we can now build our own projects that measure temperature and humidity.
