Frequently Asked Questions

What is the operating voltage range for the OPT3004 sensor module?

The module operates from a supply voltage of 1.6V to 3.6V. Its I2C communication pins are 5.5V tolerant, allowing direct connection to 5V microcontroller systems like most Arduino boards without requiring a logic level shifter.

How does the OPT3004 achieve accurate Lux readings?

The OPT3004 uses a precision optical filter that blocks over 99% of infrared light, ensuring its spectral sensitivity closely matches the human eye's photopic response. This IR rejection prevents inaccurate Lux readings caused by heat sources or IR-rich lighting.

What is the communication protocol and how do I connect it to an Arduino?

The module communicates via the I2C protocol. Connect the module's VCC to 3.3V, GND to GND, SDA to the Arduino's SDA pin (e.g., A4 on Uno), and SCL to the SCL pin (e.g., A5 on Uno). Use the OPT3004 library to read Lux values over I2C.

Can this sensor be used in battery-powered devices?

Yes, its ultra-low typical operating current of 1.8µA makes it ideal for battery-powered and energy-harvesting applications. You can put the sensor into a low-power shutdown mode via I2C commands to further conserve energy between measurements.
