DHT22 AM2302 Digital Temperature and Humidity Sensor

The DHT22 (AM2302) is a highly accurate, basic, low-cost digital temperature and humidity sensor. It utilizes a capacitive humidity sensor and a thermistor to measure the surrounding air, outputting a reliable digital signal on the data pin. Perfect as a superior replacement for the DHT11, SHT11, or SHT15, this sensor offers a wider measurement range and better precision, making it an essential component for any climate monitoring system.

Widely used in weather stations, HVAC systems, smart home automation, and IoT agriculture projects, the DHT22 provides excellent long-term stability. It is fully compatible with 3.3V and 5V logic microcontrollers, ensuring seamless integration with standard development boards like Arduino, Raspberry Pi, and ESP32. Whether you are analyzing a circuit diagram for a custom PCB or looking to buy online in India for a reliable data logger, the DHT22 delivers trusted environmental data.

Features:

• High Precision: Offers temperature accuracy of ±0.5°C and humidity accuracy of ±2% RH.
• Wide Range: Accurately measures temperatures from -40°C to 80°C and humidity from 0% to 100% RH.
• Digital Output: Utilizes a single-bus digital signal for easy data acquisition without requiring analog pins.
