About this product
A digital light sensor module based on the TSL2561 light-to-digital converter, which communicates over I2C. It has both infrared and full-spectrum photodiodes, so infrared, full-spectrum and visible light can be measured separately, which better matches human eye response. Suitable for ambient light measurement and lighting control projects.
