Description
The AM2320 is a compact temperature and humidity sensor that offers the convenience of an I2C interface, making it much easier to integrate into projects compared to traditional DHT sensors that require complex bit-banging protocols. With this I2C communication, you can easily connect the sensor to a microcontroller without needing to worry about precise timing.
While the sensor’s documentation is limited, it claims a 3% humidity accuracy and 0.5°C temperature accuracy. However, based on real-world use, we recommend keeping in mind that the temperature may be off by 2-3°C, and humidity could vary by 5-10%. Despite these limitations, the AM2320 offers an excellent balance of simplicity, affordability, and functionality, making it a great choice for maker and IoT projects where high accuracy is not critical.
Each order includes one AM2320 sensor, and you will need an I2C-compatible microcontroller and two I2C pull-up resistors (which are not included) to use it. We provide ready-to-go Arduino and CircuitPython code to get you started, along with a detailed guide that includes wiring diagrams, code examples, and the datasheet.
