As a result, the DHT11 (blue) is cheaper, but the DHT22 (white) is more precise and lasts longer. For applications in “extreme” areas (020% or 80 humidity), the DHT22 should be used, as it also supports these areas in contrast to the DHT11. For example, I have a DHT22 sensor in my fridge to measure and log temperature and humidity.
DHT11 is perhaps the most popular, widely used, and reliable temperature and humidity sensor module for Arduino based projects. It can measure humidity from 20% to 90% RH and temperature from 0 to 50 degrees Celsius. The best thing about KeeYees DHT11 is that you can operate it with both and 5 Volts power.
Humidity Sensor Introduction Humidity Sensor DHT11 Module A humidity sensor senses,measures and regularly reports the relative humidity in the air.

Nov 17, 2014· it is due to the capabilities of the sensor itself. It returns 5 bytes just like the DHT22 (same handshake) and 2 of the bytes (decimal part) are always zero for the DHT11. And because the sensor itself behaves that way, the lib does not support a decimal part for the DHT11, it would make no sense. Renderer November 15, 2014, 2:00pm 11.
