Solid basic sensor
If you need high precision, look elsewhere. For general home automation triggers, this is perfect and cheap.

Great for school projects
Bought five for a class project. All worked out of the box. Humidity readings seem accurate compared to a hygrometer.

Good value but slow
Reliable sensor for the price. Just remember it has a 1-second sampling rate limit. Not for rapid changes.

Perfect for Arduino Projects
Works exactly as expected. Easy to wire up with the standard library. Readings are consistent for indoor monitoring.
5 FAQ
Q: Does this work with 3.3V logic?
A: Yes, it operates between 3.3V and 5.5V. Suitable for ESP32 and Raspberry Pi GPIO.
Q: What is the sampling rate?
A: The sensor requires at least 1 second between readings to ensure data integrity.
Q: Is this sensor waterproof?
A: No, the DHT11 is not waterproof. Please keep it in a dry environment.
Q: Which library should I use?
A: The standard DHT sensor library by Adafruit works perfectly with this module.
Q: How many pins need connecting?
A: Usually 3 pins are used: VCC, Data, and GND. The third pin is often NC (No Connect).
