Що таке DHT 11?

What does DHT11 do?

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It's fairly simple to use but requires careful timing to grab data.

What is the range of DHT11?

0°C to 50°C The DHT11 sensor temperature range is 0°C to 50°C and the lower temperature limit is reached when it reports 1°C. The temperature descends below that value, but the sensor is not capable of reading lower and saturates. DHT22, BME280, HTU21D, and SHT31 sensors can read temperature values down to -40°C.

What is the difference between DHT11 and DHT 12?

The DHT12 builds upon the DHT11, offering additional features like compatibility with I2C communication and improved accuracy. Its compact size and low power consumption make it suitable for a wide range of applications. I2C Communication Protocol: DHT12 supports both single-wire and I2C communication.

What are the connections for DHT11?

Wiring DHT11 Module to Arduino Connections are relatively simple. Begin by connecting the + (VCC) pin to the Arduino's 5V output and the – (GND) pin to ground. Finally, connect the Out pin to digital pin #8. The diagram below shows how to connect everything.
