1. Learning Objective
To understand the basic concept of a sensor and evaluate how a microcontroller (ESP32) receives physical environment variations and transforms them into readable text and numeric data in real time through the Wokwi Serial Monitor.
2. Activity Instructions
For this activity, the source code is already pre-loaded into the ESP32's memory. Your mission as a team is to assemble the hardware connections on the screen and analyze how the data travels.
-Open the Wokwi simulation platform.
-Click on the Add Component (+) button and add two elements to the workspace: an ---ESP32 DevKit v1 and a DHT22 (temperature and humidity sensor).
-Connect the wires using your mouse, linking the pins of both components exactly as --indicated in the Hardware Connection Map.
-Once the wiring is complete, press the green Start Simulation (Play) button.
-Open the Serial Monitor tab at the bottom of the interface, click directly on the DHT22 sensor to move its environment sliders, and complete this worksheet.
