Description
The DHT22 Digital Temperature and Humidity Sensor Module is a high-precision sensor ideal for a wide range of DIY electronics and Arduino-based projects. This red PCB module combines a capacitive humidity sensor and a thermistor to measure surrounding air conditions with excellent reliability and stability.
Unlike its smaller sibling (DHT11), the DHT22 offers improved accuracy and a wider measurement range, making it suitable for weather stations, environmental monitoring, smart homes, and automation systems.
This module outputs data via a single digital pin, making it simple to interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
