About this product
A DHT22 (AM2302) digital sensor module that measures temperature and relative humidity over a single data wire. It covers 0–100 % RH and -40 to 80 °C, with a response time of up to 2 s, and is widely used in Arduino, ESP32 and Raspberry Pi weather and environment projects.

Do I need a pull-up resistor on the data line?
Most DHT22 modules already include a pull-up resistor on the DATA pin. If your bare sensor or module lacks one, connect a 4.7 to 10 kΩ resistor between DATA and VCC. Connect VCC to 3.3 V or 5 V, GND to ground, and DATA to any digital pin.
How often can I read the sensor?
Wait at least 2 seconds between readings. Reading faster than this returns invalid or repeated values, so add a delay in your code between sensor calls.
