Frequently Asked Questions

What is the difference between the I2C and single-bus communication modes on the AM2322?

The AM2322 supports two protocols. The I2C mode uses a standard 2-wire interface (SCL, SDA) for direct connection to microcontroller I2C buses. The single-bus (1-Wire) mode uses a single data line for communication, which can simplify wiring in distributed sensor networks. Both modes output fully calibrated digital data.

What is the operating voltage range for the AM2322 sensor?

The module has a rated voltage of 5.5 VDC. It is typically operated at 3.3V or 5V logic levels, compatible with most development boards like Arduino Uno (5V) or ESP32/ Raspberry Pi (3.3V). Ensure your power supply does not exceed the maximum 5.5V rating.

Does the sensor output require any additional calculation or temperature compensation?

No. The onboard microprocessor performs all necessary temperature compensation and calibration. The digital output provides direct, accurate temperature and humidity values along with a CRC checksum. Users do not need to perform secondary calculations.

What is the typical accuracy and resolution of the humidity measurement?

The sensor has a typical humidity accuracy of ±2% RH and a resolution of 0.024% RH. The integrated temperature sensor provides corresponding precision for accurate dew point and absolute humidity calculations when used in environmental monitoring applications.
