DHT20 - AHT20 Pin Module - I2C Temperature and Humidity Sensor

The DHT20 is an affordable yet excellent temperature and humidity sensor from the same makers of the DHT22. It closely resembles the well - known DHT11/DHT22 sensors. But here's the big difference: it has an I²C interface. You don't have to deal with a bit - bang timing - specific protocol. Just use plain - old I²C! It can be powered by a voltage ranging from 2.5V to 5.5V, making it compatible with both 3V and 5V microcontrollers. Inside the DHT20 is the AHT20. You can take sensor readings as frequently as you want. Using standard I2C, it's a breeze to use with any Arduino or Linux/Raspberry Pi board. This sensor offers a typical accuracy of ±2% relative humidity and ±0.3 °C at 20 - 80% RH and 20 - 60 °C. However, it has only one I2C address, so it's not ideal if you need multiple humidity sensors. For maker and IoT projects, its simplicity and low price are unbeatable. We also provide ready - to - use Arduino and CircuitPython code. Check out our detailed guide for library code, datasheet, and more. Each order includes one DHT20 pin module sensor with built - in pullups. All you need is a microcontroller that can run our Arduino or CircuitPython library.

Using the DHT20 sensor is easy. First, connect the sensor to your microcontroller. Make sure the power supply is between 2.5V and 5.5V. Then, install the provided Arduino or CircuitPython library on your microcontroller. Once the library is installed, you can start taking temperature and humidity readings. You can take readings as often as you like. Note that this sensor has only one I2C address, so it's not suitable if you need multiple humidity sensors. For maintenance, keep the sensor in a clean and dry environment. Avoid exposing it to extreme temperatures or humidity levels. If you have any questions, refer to our detailed guide with library code and datasheet.
