GY-2561 TSL2561 Ambient Light Sensor Module

The GY-2561 is a TSL2561 Ambient Light Sensor Module made by Philips Electronics - NXP. The absolute maximum ratings table on this page lists the 3 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the GY-2561 maximum ratings, with the full datasheet PDF to preview below or download.

GY-2561 TSL2561 Ambient Light Sensor Module integrating sensor is a sophisticated light sensor that has a flat response across most of the visible spectrum. Unlike simpler sensors, the TSL2561 measures both infrared and visible light to better approximate the response of the human eye. And because the TSL2561 is an integrating sensor (it soaks up light for a predetermined amount of time), it is capable of measuring both small and large amounts of light by changing the integration time.

The TSL2561 is capable of direct I2C communication and is able to conduct specific light ranges from 0.1 - 40k+ Lux easily. Additionally, the TSL12561 contains two integrating analog-to-digital converters (ADC) that integrate currents from two photodiodes, simultaneously. Each breakout requires a supply voltage of 3V and a low supply current max of 0.6mA.
