Q & A

What components are required for the weather monitoring experiment?

The experiment requires a Node MCU board, breakout board, LCD display with I2C converter, breadboard, DHT11 sensor, BMP280 sensor, LDR sensor, rain sensor, connecting wires, and a power source.

How do you create a new thing on the Arduino IoT Cloud?

To create a new thing, sign in to the Arduino IoT Cloud, go to 'Things' in the left menu, click the '+' button, rename the thing (e.g., 'weather monitoring system'), and then add the necessary variables.

What variables are added to the weather monitoring system?

Five variables are added: temperature, humidity, pressure, rain (integer), and light (Boolean).

How do you link variables to widgets in the dashboard?

To link variables, you select the corresponding variable from the list when adding a widget, such as a gauge or chart, in the dashboard configuration.

What are the maximum values set for the gauges in the dashboard?

The maximum values set for the gauges are 100 for temperature and humidity, 100,000 for pressure, and 500 for rain.

What device is used in the weather monitoring system?

The device used is the ESP8266 board, specifically the Node MCU 1.0 model.

How is the network configured in the IoT Cloud?

To configure the network, you enter the Wi-Fi username, password, and the secret key copied from the setup process, then click 'Save'.

What programming language is used for the Node MCU code?

The code for the Node MCU is written in C++ and is uploaded using the Arduino IDE.

How can users check the output of the weather monitoring system?

Users can check the output by downloading the IoT Remote application from the Play Store, where they can view the created dashboard with gauges and charts.

What logic is implemented in the code for reading sensors?

The code reads data from the DHT11 sensor for temperature and humidity, the BMP280 sensor for pressure, and checks the light and rain sensors, assigning their values to the corresponding variables.
