Lab 1: Temperature & Humidity Sensors

Overview​

Temperature & humidity sensing is a foundational IoT use case. In this lab you build an IoT dashboard that displays temperature and humidity in real time.

Requirements​

Design and implement an IoT dashboard that displays temperature and humidity in real time, using an ESP32 / ESP32-S3 and a DHT20 / DHT11 sensor.

Instructions​

  1. Run a "Hello World" example to verify the board and toolchain.
  2. Run a DHT20 example to read the sensor and print values to the serial monitor.
  3. Build the dashboard and stream live readings.

Test​

Connection test: watch the temperature on the dashboard, then warm the sensor with your breath or finger and confirm the value changes.

Questions​

  • List the technical specifications of your temperature/humidity monitoring solution.
  • Write deployment instructions and notable points.
