  • Onboard voltage translator supports 3.3V and 5V logic levels
  • New development board ready for IoT edge integration

LTR390-UV Ultraviolet Sensor Board

The LORDWORLD LTR390-UV development board measures ultraviolet and visible light intensity for IoT edge applications. An embedded ADC delivers direct digital readings through an I2C interface, reducing noise in the signal path. Onboard voltage translation allows operation with 3.3V or 5V logic levels.

Makers adding UV index monitoring to environmental

Suits developers who need a ready-to-use module with programmable interrupt thresholds for alert-driven designs. Not suited for projects that require multi-sensor fusion on a single board or wireless connectivity without an external host controller.

I2C interface with 3.3V and 5V logic compatibility

The board communicates over I2C and includes a voltage translator so it connects directly to either 3.3V or 5V microcontrollers. This single electrical characteristic determines whether the module integrates without additional level-shifting circuitry.

Perguntas sobre este artigo

How much current does the LTR390-UV sensor draw when it runs continuously?

The onboard LTR390-UV-01 draws very little current, so heat and noise stay negligible during all-day operation

Which host controller and voltage level do I need to talk to the I2C pins?

Any 3.3 V or 5 V microcontroller with an I2C bus can drive the module directly thanks to the onboard voltage translator

Will this board work alongside a classic 5 V Arduino Uno without extra level shifters?

Yes, the built-in translator makes the I2C lines safe for both 3.3 V and 5 V logic, so older 5 V boards connect straight away
