Original DHT22 Digital Temperature and Humidity Sensor

Original DHT22 Digital Temperature and Humidity Sensor

Introducing the Original DHT22 Digital Temperature and Humidity Sensor (AM2302), a reliable and cost-effective solution for monitoring temperature and humidity in your environment. This sensor uses a capacitive humidity sensor and a thermistor to provide accurate readings, with a digital signal output through the data pin.

The DHT22 is well-regarded for its high accuracy and excellent temperature compensation, ensuring precise measurements of both relative humidity and temperature. It is calibrated for consistent performance, offering outstanding long-term stability.

With a simple 3-pin connection, the DHT22 is easy to integrate into your projects. Just connect the power supply (3.3-6V DC), the data input pin, and ground to start collecting data. Each sensor has its own data pin, allowing for the independent operation of multiple sensors.
