Frequently Asked Questions

What is the operating voltage range for this sensor module?

The module is designed to operate from 3.3V to 5V DC, making it directly compatible with most common microcontroller platforms like Arduino (5V) and Raspberry Pi/ESP32 (3.3V). Ensure your power supply can provide the typical 45mA operating current.

How do I switch between I2C and UART communication modes?

The module features a hardware switch or Jumper selection (consult the product diagram) to configure the output interface. For I2C mode, connect the SDA and SCL pins. For UART mode, connect the TX and RX pins, ensuring proper logic level matching (3.3V or 5V) with your host controller.

Does the module require calibration, or does it output processed data?

The onboard MCU handles all sensor calibration and data processing, outputting fully converted values in standard units: temperature in °C/°F, humidity in %, pressure in kPa, ambient light in lux (lx), and UV intensity in mW/m². You can use the provided Arduino or Python libraries to read these values directly.

What is the measurement range and accuracy for the UV sensor?

The integrated ML8511 sensor is sensitive to UV-A (320-400nm) and UV-B (280-320nm) wavelengths. Its output in mW/m² corresponds to the ultraviolet light intensity. For specific accuracy and linearity specifications, refer to the ML8511 datasheet, as the module's onboard processing provides a digital representation of the analog sensor output.
