It works seamlessly with Arduino, ESP8266, D1 Mini, Raspberry Pi, and other common microcontrollers.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I connect the DHT22 module to my microcontroller?\u003c\/h4\u003e\n\u003cp\u003eA: The module features a simple 3-pin interface — VCC (power), DATA (signal), and GND (ground). Connect VCC to a 3.3V or 5V supply, GND to ground, and DATA to any available digital input pin on your microcontroller. The onboard pull-up resistor means no extra components are required. Use the standard DHT22 library in the Arduino IDE for quick setup.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the difference between DHT11 and DHT22?\u003c\/h4\u003e\n\u003cp\u003eA: The DHT22 offers significantly higher accuracy and a wider measurement range than the DHT11. The DHT22 measures temperatures from -40°C to +80°C with ±0.5°C accuracy, while the DHT11 is limited to 0–50°C. For humidity, the DHT22 provides ±2–5% RH accuracy versus ±5% for the DHT11, making it the preferred choice for more demanding applications.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this module compatible with the D1 Mini (ESP8266)?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The DHT22 AAM2302B module is fully compatible with the D1 Mini (ESP8266), Arduino boards, Raspberry Pi, and virtually any 3.3V or 5V microcontroller platform. It is a popular choice for ESP8266-based IoT and Wi-Fi sensor projects.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
