|Post subject:||TSL2561 Luminosity Sensor Module (HCMODU0102)|
The TSL2561 (HCARDU0102) Luminosity sensor module is a light to 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 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 on-board regulator means the module can be powered from a convenient 5V source.

Raspberry Pi users:
For Raspberry Pi uses we have tested this module with the free Cayenne cloud based IoT software platform. Simply connect the module to your Raspberry Pi as shown below and use the Cayenne software platform to get remote luminosity readings without writing a single line of code.

To make using this module with your Arduino as easy as possible we have written an exclusive library (HCTSL2561). This library can be downloaded from the software section of our support forum here:
The library will allow you to obtain readings from both sensors. Additionally, it can use the information from both sensors to perform a calculated Lux measurement as perceived by the human eye.
