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.

How does the DHT 11 sensor provide readings for temperature and humidity?

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

What is the significance of the delay time in the code?
