Product description: Light intensity sensor LTR-329 - STEMMA QT / Qwiic - Adafruit 5591
The sensor manufactured by Adafruit enables the measurement of light intensity for both the infrared spectrum and visible light . Based on the LTR-329 system, it allows for measurement in the range from 0.01 lux to 64000 lux with a measurement resolution of 16 bits . The module uses the I2C bus to communicate with the connected microcontroller, thanks to which it can be integrated into a wide range of projects. The supply voltage of the sensor is from 3 V to 5 V DC .
Product compatible with Arduino and Raspberry Pi!

Light intensity sensor LTR-329 - STEMMA QT / Qwiic - Adafruit 5591.
Description of the sensor pins from Adafruit
The light sensor can be connected in two ways. The first of them uses solder pads to which the goldpin bar with a raster of 2.54 mm (included in the set) should be soldered. Alternatively, the sensor also has a STEMMA QT / Qwiic connector , which allows for quick and convenient connection of the module, without the need to solder the elements.
- VIN - power supply pin in the range from 3 V to 5 V DC
- 3Vo - 3.3 V power supply pin
- GND - system ground
- SCL - pin of the clock line of the I2C communication interface
- SDA - pin of the data line of the I2C communication interface
