Furthermore, DHT11 is widely regarded as the humidity and temperature module for Raspberry Pi and Arduino. Therefore, due to its many benefits, hardware enthusiasts favor the DHT11. Also the DHT11 humidity temperature sensor also works with respect to the new DHT11 module. Features. Consumes low power and has a great longterm stability
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.
Sep 25, 2020· The DHT11 is a digital humidity and temperature sensor. It measures humidity from 20% to 80% with an accuracy of 5%. Similarly, temperatures range from 0°C to 50°C with ±°C accuracy.
