TSL2561 GY-2561 Light Intensity Sensor Module

The TSL2561 is an advanced digital light sensor equipped with a dual photodiode: one for full-spectrum light (visible + infrared), and the other for infrared light only. This dual configuration allows for precise ambient light sensing by measuring visible light levels, infrared, or full spectrum separately.

Main Features

• Dual photodiodes for separate detection of infrared light and full-spectrum light (visible + infrared)
• Human-visible light can be calculated by subtracting infrared from the full spectrum
• Programmable upper and lower threshold to automatically generate light level interruption
• Supports SMBUS (TSL2560) and I2C (TSL2561) communication protocols
• Programmable gain timing and integration
• Automatic rejection of 50Hz/60Hz flicker noise from artificial lighting
