The TSL2772EVM is an evaluation board used to evaluate and demonstrate the performance of the TSL2772, an ambient and infrared light-to-digital converter. This board leverages the TSL2772 Digital Light Sensor to measure the visible ambient light, the infrared light, and the UV Index. It is built to monitor and measure ambient light and UV radiation by utilizing a single device for all three measurements.

Application Field

The TSL2772EVM can measure and track light levels in a variety of different applications. One example is in the monitoring and analysis of outdoor environment, such as solar energy measurements. Additionally, the board also supports applications that require measurement of indoor light levels, such as energy-saving programs, and monitoring in hazardous environments.

Furthermore, the board is also a great tool for research purposes. Its high resolution, wide dynamic range and exceptional linearity can provide accurate results over a wide range of measured optical signal levels. This performance makes it invaluable for evaluating the performance of the TSL2772 in many different applications.

Working Principle

The TSL2772EVM board utilizes a silicon photodiode coupled with a high performance light-to-voltage converter. The converter generates an output voltage proportional to the intensity of the received light from 0 to 16V. This voltage is then converted to a digital form by an on-board analog-to-digital converter (ADC) and can be read by an external microcontroller via an SPI bus.

The TSL2772EVM evaluation board contains two mechanical potentiometers, a digital potentiometer, a pair of Schottky diodes, an 8-bit digital potentiometer with four output pins, and an 8-output, differential output multiplexer. It also includes a programming interface board with two USB ports, a 10-pin programming connector and a debug serial port.

The evaluation board also includes a battery pack for powering and resetting the board, a power switch, and a reset button for resetting the board. Additionally, the board also features an I2C temperature sensor and a USB-C interface for connecting to the external microcontroller.

The TSL2772EVM evaluation board is a great tool for any user looking to develop and optimize their applications with the TSL2772. The flexibility and convenience provided by this evaluation board makes it an ideal choice for any light or UV sensing application.
