Good module, slight delay
Sampling rate is slow as expected for DHT22 but accurate. Good for general environmental monitoring.

5 FAQ
Q: Are wires included in the box?
A: Yes, Dupont lines are included in the kit for easy connection.
Q: What library do you recommend?
A: The Adafruit DHT sensor library works best for most microcontroller platforms.
Q: Does it work with 3.3V logic?
A: Yes, it supports operating voltages between 3.3V and 5.5V DC.
Q: Is this sensor waterproof?
A: No, the DHT22 sensor module is not waterproof and should be kept in a dry enclosure.
Q: How fast can I read data?
A: The maximum sampling rate is 0.5Hz, meaning you can read new data once every 2 seconds.
