Light Sensor, Ambient Light Detecting (Waveshare 12490) TSL2581FN I2C interface

Light Sensor, detects the ambient light intensity, I2C interface

Overview

• Features TSL2581FN with ADC, feels the ambient light just like human vision
• I2C interface directly outputs the ambient light intensity value, needs no calibration, less noise interference
• Embedded infrared photodiode, gets high precision output even in environments with strong infrared noise interference
• Features interrupt output, programmable upper/lower thresholds
• Sensitivity is about 30 times higher than TSL2560/TSL2561
• Embedded voltage level translate circuit, allows directly connecting to 3.3V/5V MCU systems

Specifications

• Resolution: 16 bit
• Operating voltage: 3.3V ~ 5V
• Dimension: 25mm × 15.5mm
• Mounting holes size: 2.0mm

Applications

• Street lamp control
• Safety lighting
• Sunshine collecting
• Robot vision

How to Use

In the case of working with a MCU:

• VCC ↔ 3.3V ~ 5V
• GND ↔ GND
• SDA ↔ MCU.I2C data pin
• SCL ↔ MCU.I2C clock pin
• INT ↔ interrupt output, optional
