The DHT22 is an advanced version of the DHT11 sensor, offering higher accuracy and a wider measurement range. It measures temperature from -40°C to 80°C and humidity from 0% to 100% RH. The sensor features a capacitive humidity sensor and a high-precision thermistor for reliable data collection. It communicates via a digital single-wire protocol, making it simple to integrate with microcontrollers like Arduino and Raspberry Pi. The DHT22 is commonly used in weather stations, greenhouse monitoring, and industrial automation. It provides improved accuracy of ±0.5°C for temperature and ±2% for humidity. The sensor has a longer response time compared to the DHT11 but delivers more precise readings. It is ideal for projects requiring accurate environmental monitoring.
