How the DHT11 Measures Humidity and Temperature At 100% RH, condensation occurs, and at 0% RH, the air is completely dry. Relative humidity is expressed as a percentage. The formula to calculate relative humidity is: Cold air can hold less water vapor before it becomes saturated, and hot air can hold more water vapor before it becomes saturated. The saturation point changes with air temperature. At the saturation point, water vapor starts to condense and accumulate on surfaces forming dew. the saturation point of water vapor in air. Relative humidity is the amount of water vapor in air vs. Here are the ranges and accuracy of the DHT11:ĭHT11 Datasheet What is Relative Humidity? It includes all of the parts, wiring diagrams, code, and step-by-step instructions for 58 different robotics and internet of things projects that are super fun to build!
