The DHT22 (AM2302) is a high-accuracy digital temperature and humidity sensor widely used in IoT, environmental monitoring, and academic research projects. Compared to the DHT11, the DHT22 offers higher precision, wider measurement range, and better stability, making it suitable for advanced prototyping and long-term experiments.
This sensor is extensively used in IoT research labs, smart agriculture, weather stations, HVAC systems, data logging projects, and industrial automation. Due to its low power consumption and long-term stability, it is a standard choice for researchers conducting climate studies, smart city prototypes, and environmental IoT networks. |
