Weather Monitor


About This Project

In this IoT project I am going to Monitor Humidity and Temperature over the internet using Cayenne where we will show the current Humidity & Temperature data over the Internet using the Cayenne server. It is accomplished by the data communications between Arduino, DHT11 Sensor Module, Ethernet Shield.

What’s Connected

Interface with components (RHT03 Humidity and Temperature Sensor, Ethernet Shield, Arduino UNO)

Photos of the Project

The DHT11 measures relative humidity. Relative humidity is the
amount of water vapor in air vs. the saturation point of water vapor in
air. At the saturation point, water vapor starts to condense and
accumulate on surfaces forming dew.

Here are the ranges and accuracy of the DHT11:

  • Humidity Range: 20-90%
  • RHHumidity Accuracy: ±5%
  • RHTemperature Range: 0-50 °C
  • Temperature Accuracy: ±2% °C
  • Operating Voltage: 3V to 5.5V

Dashboard Screenshots(Cayenne)

In Cayenne App, Fahrenheit scale thermometer and percentage scale humidity meter
displays the ambient temperature and humidity for live monitoring from anywhere in the world.
Note:Temperature values are displayed in Fahrenheit

The Judges Have Spoken! ~CONTEST RESULTS~

Nice! :thumbsup: What about putting a BMP180/280 to get pressure too from your weather station?
