Adafruit product 2831 supplier identification. Linked HW5P-1 document is a supplier reference; exact die manufacturer is not verified. Detailed wavelength, speed and absolute limits omitted.
Description
One two-lead light sensor sold by Adafruit as a photo transistor, product 2831, not an LED or optocoupler. Supplier describes a filtered human-eye-like response, 5 × 5.3 mm body and a suggested 3–15 V circuit using a roughly 1–10 kΩ load resistor; output voltage depends on that external resistor. Do not treat those usage suggestions as a complete guaranteed operating-range specification. Linked supplier datasheet identifies HW5P-1 by Shenzhen Haiwang, but no exact model marking is visible on the packaged sensor. Product: https://www.adafruit.com/product/2831
