Reliable Obstacle Detection

Used these for obstacle avoidance on my smart car. Response time is quick and no false positives so far.

Good value pack

Sensors work well. One had a slightly loose pin but I soldered it back. Detection range is accurate for the price.

Okay but sensitive to sunlight

Works great indoors. Struggles a bit in direct sunlight due to IR interference. Expected for this price point.
