Adafruit TSL2591 High Dynamic Range Digital Light Sensor – STEMMA QT

The TSL2591 is a high dynamic range digital light sensor that uses both infrared and full spectrum diodes to measure light. It can measure different types of light including infrared, full-spectrum, and human-visible light, providing a more accurate representation of what human eyes perceive. The sensor includes a built-in ADC (Analog-to-Digital Converter) which allows it to interface with microcontrollers without analog inputs.

• Avoid Using Incorrect Voltage: Do not supply the sensor with a voltage outside of the 3.3V to 5V range to prevent damage.,
• Do Not Change I2c Address: The I2C address of the TSL2591 is fixed and cannot be changed, unlike some other models.

• Use Appropriate Power Supply: Ensure the sensor is powered with a voltage between 3.3V and 5V.,
• Utilize I2c Interface: Connect the sensor using the I2C interface for communication with microcontrollers.,
• Implement Power-Down Mode For Energy Saving: Take advantage of the sensor's low power consumption features by using the power-down mode when the sensor is not actively sensing.

• Description: The sensor has a dynamic range of 600,000,000:1, allowing it to perform well under varying light conditions.

• Minimum: 188 micro lux,
• Maximum: 88,000 lux

• Minimum: 3.3V,
• Maximum: 5V

• Description: Use the SparkFun qwiic compatible STEMMA QT connectors for easy, solder-free connection to a microcontroller. Simply connect using a STEMMA QT adapter cable.
