Easy to integrate
Wiring is straightforward. Make sure to use a pull-up resistor between data and VCC for best results.

Reliable Sensor
Been using these for years. Consistent performance in varying humidity conditions. No drift observed over time.

Good value for money
Slightly slower than expected but accurate enough for my home weather station. Packaging was secure.

Great for Arduino Projects
Works perfectly with the Adafruit library. Readings are stable after a few minutes of warm-up. Highly recommended for beginners.
Q: Is this compatible with Raspberry Pi?
A: Yes, it works with Raspberry Pi GPIO pins using Python libraries.
Q: What is the max wire length?
A: Keep wires under 20 meters to ensure signal integrity and accuracy.
Q: What library do you suggest?
A: We recommend the Adafruit DHT sensor library for Arduino and CircuitPython.
Q: Do I need a resistor?
A: Yes, a 10k ohm pull-up resistor is recommended between data and VCC.
Q: Can I use this outdoors?
A: The sensor itself is not waterproof. You need an enclosure for outdoor use.
