Seeed Studio Grove Digital Light Sensor TSL2561 for Arduino
This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity into a digital signal. It has three detection modes to take your readings (infrared mode, full-spectrum, and human visible mode) and can be used to measure the change in light intensity in various light situations with many popular microcontrollers.
Features
- Flexible detection modes: Infrared mode, full-spectrum mode, and human visible mode selectable
- High-resolution: 16-Bit digital output at 400 kHz I2C Fast-Mode
- Support measurement in various lighting situations: Support a wide dynamic range of 0.1 - 40,000 LUX and a wide operating temperature range of -40℃ to 85℃
- Programmable interrupt function: User-Defined Upper and lower threshold settings
- Grove unified socket: The product ensures "Plug and Play" and could be versatile for various applications of Grove
Description
The TSL2561 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 the ADC conversions. Different from the traditional analog light sensor, such as Grove - Light Sensor, this digital module features a selectable light spectrum range due to its dual light-sensitive diodes: infrared and full spectrum.
You can switch between three detection modes to take your readings. They are infrared mode, full-spectrum, and human visible mode. When running under the human visible mode, this sensor will give you readings just close to your eye feelings. With its high-resolution and wide operating temperature range, you can use it to measure the change in light intensity in various light situations with many popular microcontrollers.
You can connect your Grove to these recommended development boards:
- Seeed Studio XIAO RP2040
- Seeed Studio XIAO nRF52840
- Seeed Studio XIAO SAMD21
- Wio-E5 CAN Development Kit

Get Started with Industrial Sensors
SenseCAP S210x series industrial sensors provide an out-of-box experience for environmental sensing. Please refer to the S2102 Wireless Light Intensity Sensor with higher performance and robustness for light intensity detection.
Applications
- Ambient light sensing
- Backlighting control for the display panel
- Keyboard illumination control
Upgrade to Industrial Solutions
With the SenseCAP S2110 controller and S2100 data logger, you can easily turn the Grove into a LoRaWAN® sensor. Seeed not only helps you with prototyping but also offers you the possibility to expand your project with the SenseCAP series of robust industrial sensors.
The IP66 housing, Bluetooth configuration, compatibility with the global LoRaWAN® network, built-in 19 Ah battery, and powerful support from APP make the SenseCAP S210x the best choice for industrial applications. The series includes sensors for soil moisture, air temperature and humidity, light intensity, CO2, EC, and an 8-in-1 weather station. Try the latest SenseCAP S210x for your next successful industrial project.
