Great for learning
Works perfectly with my Arduino Uno. The signal is clear enough for basic visualization projects.

Good value
Decent sensor for the price. You need to add some code filtering to get a stable reading.

Works as described
Sensitive to movement but that is expected for this type of optical sensor. Happy with the purchase.

Solid analog output
I connected this to an oscilloscope and the waveform looks correct for a PPG signal.
