Works with Raspberry Pi
Successfully integrated with my Pi Zero. Remember to use a pull-up resistor for stable data.

Good accuracy for the price
Compared it against a professional meter and it was within expected tolerance. Pins are a bit thin though.

Requires extra components
Sensor works well but does not include the necessary pull-up resistor. Had to order separately.
