Customer Questions & Answers

What are the limitations of the DHT11 compared with alternative sensors such as the DHT22?

The DHT11 offers lower accuracy, a narrower operating range (0–50 °C vs. -40–80 °C) and a smaller humidity range. In addition, the resolution is only 1 unit and it has a slower update time. The DHT22 is superior in these aspects, although it is more expensive.

Does the DHT11 require any maintenance and how does ambient humidity affect its durability?

It does not require any special maintenance, but exposing it to humidity above 90% continuously can reduce its service life and accuracy. It is recommended to use it in environments within its specified range and to avoid condensation.

Is the DHT11 sensor compatible with all Arduino boards?

Yes, the DHT11 sensor works with any Arduino board that supports a supply voltage between 3V and 5.5V.

What temperature range does the DHT11 sensor measure?

The DHT11 sensor measures temperatures from 0ºC to 50ºC.

What accuracy does the DHT11 sensor have for humidity and temperature?

The accuracy is ±5% for relative humidity and ±2ºC for temperature.

How do you connect the DHT11 sensor to an Arduino?

The sensor connects using a digital pin for the signal, plus power and ground. It is recommended to use specific libraries to make data reading easier.

Where can I buy the Arduino-compatible DHT11 sensor?

You can buy it at satkit, with fast shipping and quality assurance.
