I am a fifth grader. This Arduino project was inspired by Paul McWhorter. Thanks to him, I published my first project.

This project is about the DHT11 sensor displaying the temperature onto an LCD.

The sensor gathers the surrounding temperature and humidity and displays it onto an LCD.

EXPANDED TECHNICAL DETAILS

Handheld Meteorological Dashboard

A rugged, battery-powered environmental monitor designed for outdoor exploration or indoor climate audits.

  • DHT11 Digital Bus Analysis: The Arduino polls the DHT11 sensor every 2 seconds. The firmware captures the 40-st-bit data packet, providing whole-number accuracy for Humidity (±5%) and Temperature (±2°C).
  • Dynamic 16x2 I2C Display: Renders the data as: T: 25.0C H: 45%. Includes a "Minimum/Maximum" log that tracks the highest and lowest readings seen during the current session.

Efficiency

  • Power-Saving Display Toggle: Features a button that turns purely the LCD backlight on and off, significantly extending the life of the 9V battery during long-term monitoring.
