Simple Temperature and Humidity Monitor

Requires ,

This project uses a digital DHT11 sensor to measure the surrounding temperature and humidity, then displays the readings on a connected computer. It’s a basic setup ideal for beginners exploring environmental monitoring with microcontrollers.

Parts Required

  • 1 x Microcontroller (e.g., Arduino Uno or similar)
  • 1 x DHT11 temperature and humidity sensor
  • 1 x Breadboard (optional, for easier connections)
  • Jumper wires
  • USB cable for microcontroller

Assembly Instructions

  1. Power the Sensor:
    Connect the sensor’s VCC pin to the 5V pin on the microcontroller.
  2. Connect Ground:
    Connect the sensor’s GND pin to the GND pin on the microcontroller.
  3. Data Connection:
    Connect the sensor’s DATA pin to digital pin 4 on the microcontroller.
  4. Final Setup:
    Plug the microcontroller into your computer using a USB cable. The readings will appear on the serial monitor once the system is powered and running.

This simple setup enables continuous temperature and humidity monitoring using minimal components.
