Smart Home Temperature & Humidity Reader Device w/Arduino Nano, 1602A + I2C LCD Display, DHT11 Sensor & mBlock 3

This video tutorial is part of the STEM Smart Home Teaching Kit by Apricot. It guides viewers on creating a smart home device that reads temperature and humidity using a DHT 11 sensor. The tutorial covers wiring the device, connecting it to a computer, and programming it with Arduino. The video concludes with testing the device and observing changes in temperature and humidity readings.

What is the primary function of the DHT 11 sensor in the smart home device?

• To connect the device to the internet

• To display data on the screen

• To read temperature and humidity

• To control the device's power supply

Which type of wires are used to connect the components in the smart home device?

• Copper wires

• Female to male jump wires

• Male to male jump wires

• Female to female jump wires

Where should the black wire be connected on the Arduino Nano board?

• To the analog input

• To the data pin

• To the ground

• To the VCC

What software is used to run the Arduino program on a Windows 10 computer?

• Eclipse

• M Block 3

• Arduino IDE

• Visual Studio Code

What is the purpose of the 'forever loop' in the Arduino code?

• To upload the code to the Arduino board

• To continuously read and display temperature and humidity

• To connect the device to the computer

• To initialize the DHT 11 sensor

What should be done if the temperature reading is not equal to -999?

• Ignore the reading

• Reinitialize the sensor

• Display the temperature on the screen

• Disconnect the sensor

What happens to the humidity reading when you breathe on the sensor?

• It decreases

• It remains the same

• It fluctuates randomly

• It increases
