The TSL2561 Luminosity sensor module is a light to the digital interface module. The sensor contains two photodiodes, one which can detect visible light and infrared (IR), and a second which can detect IR light. Two integrating analog-to-digital converters (ADC) integrate currents from the two photodiodes to produce a digital representation of the light intensity hitting the sensor. Communication to the device is accomplished through a standard, two-wire I2C serial bus. Consequently, the TSL256x device can be easily connected to a microcontroller or embedded controller. No external circuitry is required for signal conditioning. Solderable jumper pads on the module allow 3 possible I2C addresses to be selected for up to 3 sensors or other I2C devices to co-exist on the same bus. An onboard regulator means the module can be powered from a convenient 5V source.
