3 cards from this section. Quick, good the night before a test.
What pin do we connect the data pin of the DHT11 sensor to on the ESP32?
Check the manual for GPIO pin mapping.
Is the DHT11 sensor primarily used for measuring temperature or voltage?
Think about the name of the sensor.
Which microcontroller is used in the Smart Temperature Monitor project?
Review the microcontrollers discussed.
True or False: The DHT11 sensor can measure voltage.
Consider the purpose of the DHT11 sensor.
Design an IoT system where the temperature data from the DHT11 also triggers an alert when exceeding a specific value. What additional components would you need?
Think about components that can boot up based on conditional programming.
Write a function that modifies the frequency of data sent to Firebase based on user input through the dashboard. How would it be implemented?
Consider user interaction and its impact on timing!
