Temperature and humidity
DHT22 is a popular digital sensor used to measure temperature and humidity in a wide range of applications. It is a versatile and easy-to-use sensor that provides both the temperature and humidity readings in a single module. The DHT22 is known for its reliability and accuracy in measuring environmental conditions.
Specifications
Temperature: -40°C to 80°C with an
accuracy of ±0.5°C.
Humidity: 0% to 100% relative
humidity (RH) with an accuracy of
±2-5% RH.
DHT22 operates with a 3.3V to 6V
power supply, making it compatible
with a wide range of
microcontrollers like Arduino,
ESP32, and Raspberry Pi.
The sensor communicates with a
microcontroller through a single
digital signal, which is read via the
data pin. The DHT22 uses a
proprietary digital signal
communication protocol, sending
both the temperature and humidity
data in a 40-bit format.
