About this item

The Digilent Pmod ALS is a compact ambient light sensor module designed for seamless integration into embedded systems requiring light level detection. It utilizes the Vishay TEMT6000X01 phototransistor, which exhibits peak sensitivity at 570 nm and operates within a spectral range of 440 to 800 nm, closely mimicking human eye responsiveness. The module converts the analog signal from the light sensor into an 8-bit digital output using the Texas Instruments ADC081S021 analog-to-digital converter, providing a resolution from 0 (dark) to 255 (bright). This data is transmitted via a 6-pin SPI interface, ensuring compatibility with various microcontrollers and FPGA boards. With a small form factor of 0.8" × 0.8" (2.0 cm × 2.0 cm), it is ideal for space-constrained applications. Operating at a typical voltage of 3.3V, the module draws a minimal current of 0.37 mA, making it energy-efficient for battery-powered projects. The Pmod ALS is suitable for applications such as automatic lighting systems, display brightness adjustment, and ambient light monitoring in IoT devices. It adheres to the Digilent Pmod Interface Specification Type 2, ensuring reliable performance and easy integration into existing systems.
