Good Value for Money
Sensor works as expected. Had to adjust the LED current settings for better readings on darker skin tones.

Easy to Integrate
Pinout is standard. Connected to ESP32 without any level shifters. Readings are consistent.

Sensitive to Light
Works well indoors but ambient sunlight interferes with the IR sensor. Needs shielding.
