Frequently Asked Questions
Q: Is the TSL2591 light sensor breakout module compatible with Arduino and Raspberry Pi?
A: Yes! The TSL2591 I2C breakout module communicates over the standard I2C (IIC) protocol, making it fully compatible with Arduino, Raspberry Pi, ESP8266, ESP32, STM32, and virtually any microcontroller with I2C support. Libraries are widely available for quick setup.
Q: Does this module work with both 3.3V and 5V microcontrollers?
A: Absolutely. The TSL2591 breakout board supports a supply voltage range of 3.3V to 5V, so it works directly with both 3.3V systems (like Raspberry Pi and ESP32) and 5V systems (like standard Arduino Uno) without requiring a separate voltage level shifter.
Q: What makes the TSL2591 better than simpler light sensors like the LDR or BH1750?
A: The TSL2591 features an exceptionally high dynamic range of up to 600M:1, separate IR and full-spectrum photodiode channels, and programmable gain & integration time settings. This allows it to accurately measure lux levels across a far wider range of lighting conditions — from near-total darkness to direct bright sunlight — making it ideal for precision ambient light sensing applications.
Q: How many modules are included in the pack?
A: This listing offers a choice of 1, 2, or 3 TSL2591 breakout modules. Simply select the quantity that suits your project needs at checkout.
