Weather Station Using Arduino UNO R4 WiFi & Visuino

In this tutorial we will learn how to make a simple weather station using the Arduino UNO R4 WiFi board & Visuino to display Temperature & Humidity values on the matrix display.

Watch the video!

• Arduino UNO R4
• DHT11 sensor
• Jumper wires
• Visuino program: Download Visuino

• Connect DHT11 Sensor pin (VCC +) to Arduino pin [+5V]
• Connect DHT11 Sensor pin (GND -) to Arduino pin [GND]
• Connect DHT11 Sensor pin (S) to Arduino pin digital (2)

Start Visuino as shown in the first picture Click on the "Tools" button on the Arduino component (Picture 1) in Visuino When the dialog appears, select "Arduino UNO R4 WiFi" as shown on Picture 2

• Add "DHT11" component
• Add "Pulse Generator" component
• Add "Analog Toggle Switch" component

• Select ArduinoUNO R4 WiFi board and in the properties window expand Modules>Display and select Elements and click on the 3 dots button, in the Elements window drag "Text Field" to the left side and in the properties window set "Wrap" to False
• Close the Elements window

• Select "PulseGenerator1" and in the properties window set "Frequency" to 0.1

• Connect "HumidityThermometer1" pin [Temperature] to "ToggleSwitch1" pin [False]
• Connect "HumidityThermometer1" pin [Humidity] to "ToggleSwitch1" pin [True]
• Connect "HumidityThermometer1" pin [Sensor] to Arduino digital pin [2]
• Connect "PulseGenerator1" pin [Out] to "ToggleSwitch1" pin [Select]
• Connect "ToggleSwitch1" pin [Out] to  ArduinoUNO R4 WiFi > Display > "Text Field1" pin [In]

In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

If you power the Arduino module the LEDs on the Arduino Display will start to display the Temperature and Humidity values.

Congratulations! You have completed your project with Visuino. Also attached is the Visuino project, that I created for this tutorial, you can download it and open it in Visuino: https://www.visuino.com
