Frequently Asked Questions

What is the operating voltage range for this AHT30 sensor module?

The module operates from 3.0V to 5.5V DC, making it directly compatible with both 3.3V logic systems (like ESP32, Raspberry Pi) and 5V systems (like standard Arduino boards) without requiring a logic level shifter.

How do I connect this sensor to a microcontroller like Arduino or ESP32?

Connect the module's I2C pins (SDA and SCL) to the corresponding pins on your microcontroller. The module includes a 1-meter cable, typically with a 4-pin connector that can be adapted. Ensure you also connect the VCC (3-5.5V) and GND pins. Use standard I2C libraries to read the calibrated digital temperature and humidity data.

What is the purpose of the cotton core inside the white shell?

The built-in cotton core acts as a simple filter, allowing air to reach the MEMS sensing element while preventing dust and larger particulates from entering. This helps maintain long-term sensor accuracy and stability in non-cleanroom environments by protecting the sensitive capacitive humidity film.

Can I change the I2C address of the AHT30 sensor?

No, the AHT30 chip has a fixed I2C address (typically 0x38). If you need to connect multiple sensors on the same bus, you will require an I2C multiplexer (like the TCA9548A) to manage separate channels for each sensor module.
