Frequently Asked Questions

What is the operating voltage range for the AM2108 sensor module?

The AM2108 module is rated for operation up to 5.5 Volts DC. It is compatible with common 3.3V and 5V logic levels used by microcontrollers like Arduino, ESP32, and Raspberry Pi, ensuring flexible integration into various digital systems.

How do I communicate with the AM2108 sensor?

The AM2108 uses a standard I2C (Inter-Integrated Circuit) digital communication protocol. You simply need to connect the SDA and SCL pins to your microcontroller's corresponding I2C bus, along with power and ground, and use the appropriate library to read the calibrated temperature and humidity data.

What is the typical response time for humidity measurements?

The sensor has a response time of approximately 30 seconds to reach 63% of a step change in humidity. This performance is suitable for monitoring environments where changes are not extremely rapid, such as in room climate control or data logging applications.
