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