Seeed Studio Grove Digital Light Sensor TSL2561 for Arduino
This module is based on theĀ I2C light-to-digital converter TSL2561Ā to transformĀ light intensityĀ into aĀ digital signal. It has threeĀ detection modesĀ to take your readings (infrared mode,Ā full-spectrum, andĀ human visible mode) and can be used to measure the change inĀ light intensityĀ in variousĀ light situationsĀ with many popularĀ microcontrollers.
Features
- FlexibleĀ detection modes:Ā Infrared mode,Ā full-spectrum mode, andĀ human visible modeĀ selectable
- High-resolution:Ā 16-Bit digital outputĀ atĀ 400 kHz I2C Fast-Mode
- Support measurement in variousĀ lighting situations: Support a wideĀ dynamic rangeĀ ofĀ 0.1 - 40,000 LUXĀ and a wideĀ operating temperature rangeĀ ofĀ -40ā to 85ā
- ProgrammableĀ interrupt function: User-Defined Upper and lowerĀ threshold settings
- GroveĀ unified socket: The product ensures "Plug and Play" and could be versatile for various applications ofĀ Grove

Description
TheĀ TSL2561Ā is controlled and monitored by sixteen registers (three are reserved) and a command register accessed through the serial interface. These registers provide for a variety of control functions and can be read to determine the results of theĀ ADC conversions. Different from the traditionalĀ analog light sensor, such asĀ Grove - Light Sensor, thisĀ digital moduleĀ features a selectableĀ light spectrum rangeĀ due to its dualĀ light-sensitive diodes:Ā infraredĀ andĀ full spectrum.
You can switch between threeĀ detection modesĀ to take your readings. They areĀ infrared mode,Ā full-spectrum, andĀ human visible mode. When running under theĀ human visible mode, this sensor will give you readings just close to your eye feelings. With itsĀ high-resolutionĀ and wideĀ operating temperature range, you can use it to measure the change inĀ light intensityĀ in variousĀ light situationsĀ with many popularĀ microcontrollers.
You can connect yourĀ GroveĀ to these recommendedĀ development boards:
- Seeed Studio XIAO RP2040
- Seeed Studio XIAO nRF52840
- Seeed Studio XIAO SAMD21
- Wio-E5 CAN Development Kit
We have developed more than 400Ā Grove modules, covering a wide range of applications that can fulfil various needs. Click to explore theĀ Grove Sensor familyĀ and get started toĀ GroveĀ your Idea. For allĀ GroveĀ users (especially beginners), we provide you with guidanceĀ PDF documents. Please download and read through Preface - Getting Started and Introduction toĀ GroveĀ before your use of the product.
