The TSL2561 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 up to 0.1 - 40,000+ 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 Adafruit cannot perceive the IR light that is detected by most photo diodes)

New! As of June 3, 2014 Adafruit are shipping a version with a 3.3V regulator and level shifting circuitry so it can be used with any 3-5V power/logic microcontroller.

The sensor has a digital (i2c) interface. You can select one of three addresses so you can have up to three sensors on one board - each with a different i2c address. 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 its great for low power data-logging systems. about 0.5mA when actively sensing, and less than 15 uA when in powerdown mode.

Of course, Adafruit wouldn't leave you with a datasheet and a "good luck!" - Adafruit wrote a detailed tutorial showing how to wire up the sensor, use it with an Arduino and example code that gets readings and calculates lux

  • Handheld UV Meter
  • UV is important to reptiles (and people) in processing vitamin D3 which is needed to absorb calcium. Without it reptiles often suffer from Metabolic Bone Disease (MBD) which leads to weak bones and can be fatal. Thankfully, pet shops have the answer, UV producing globes which can stave off the dreaded MBD. These are in the form of T8 florescent tubes or compact florescent globes and go for $50+ each. And, yeah, they need to be re...

    Good sensitivity and responsiveness in low light, (Posted on 4/05/2017)

    Works very well using the Adafruit info and library. Good light sensitively.
    Would be perfect if there would be an official cosine response diffuser available for this illuminance sensor. (Posted on 21/03/2017)
