Looking for Tsl2591 Sensor? Adafruit TSL2591 High Dynamic Range Digital Light Sensor – STEMMA QT is available at Zbotic with fast shipping across India.
The TSL2591 luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations. Compared to low-cost CdS cells, this sensor is more precise, allowing for exact lux calculations, and can be configured for different gain/timing ranges to detect light ranges from 188u lux up to 88,000 Lux on the fly.
The best part of this sensor is that it contains both infrared and full spectrum diodes! That means you can separately measure infrared, full-spectrum, or human-visible light. Most sensors can only detect one or the other, which does not accurately represent what human eyes see (since we cannot perceive the IR light that is detected by most photo diodes) This sensor is much like the TSL2561 but with a wider range (and the interface code is different). This sensor has a massive 600,000,000:1 dynamic range! Unlike the TSL2561 you cannot change the I2C address, so keep that in mind.
The built-in ADC means you can use this with any microcontroller, even if it doesn’t have analog inputs. The current draw is extremely low, so it’s great for low-power data-logging systems. about 0.4mA when actively sensing, and less than 5 uA when in power-down mode.
As if that weren’t enough, we’ve also added SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don’t even need to solder. Just wire up to your favorite micro with a plug-and-play cable to get data ASAP. For a no-solder experience, just wire up to your favorite micro using a STEMMA QT adapter cable. The Stemma QT connectors also mean the TSL2591 can be used with our various associated accessories. QT Cable is not included, but we have a variety in the shop.

Frequently Asked Questions
Can I use this sensor directly with a 5 V microcontroller?
Yes. The onboard regulator accepts 3.3–5 V input and provides the correct operating voltage for the TSL2591, making it safe to connect to 5 V logic without additional level shifting.
How do I measure visible and infrared light separately?
The TSL2591 contains two photodiodes—one sensitive to full spectrum (visible + IR) and one to infrared only. Use library functions to read each channel individually and calculate the human-visible lux by subtracting IR from the full-spectrum reading.
How can I add more than one TSL2591 to the same I²C bus?
Each TSL2591 supports two selectable I²C addresses (0x29 or 0x28). Solder the address-select jumper to switch between them, allowing up to two sensors on one bus without address conflicts.
