TSL2561 Light Intensity Sensor Module

The TSL2561 is a high-precision light sensor module that provides accurate measurement of light levels in a variety of environments. It uses a dual photodiode design, which allows it to detect both visible and infrared light, providing a wide dynamic range and excellent sensitivity. The module is designed to operate over a wide range of temperatures and light levels, making it ideal for a variety of applications.

This light sensor can be used with the Arduino, ESP32, Teensy or ESP8266 microcontrollers.  The module communicates over I2C, which is a common interface supported by most microcontrollers. However, it’s important to note that the I2C logic levels of the module are fixed to 3.3V. So, if you’re using a 5V microcontroller, you will need to use a logic-level converter to ensure proper communication between the module and the microcontroller.

Specifications:

• Supply voltage: 3.3V to 5V
• Interface: I2C
• Measuring range: 0.1 – 40,000+ Lux
• Spectral response: 320nm – 1050nm
• Peak sensitivity: 560nm
• Dynamic range: 16-bit
• Integration time: 13.7ms to 400ms
• Current consumption: 0.5mA (typical)
• Operating temperature range: -40°C to +85°C
• Dimensions: 16mm x 13mm x 2.2mm

The TSL2561 is a versatile and accurate light sensor module that can be used in a variety of applications. Its small size and low power consumption makes it ideal for use in portable and battery-powered devices. Its wide dynamic range and excellent sensitivity make it a reliable choice for a variety of different use cases.
