Review on 10pcs/Pack DIYmall Arduino Smart Car Robot IR Infrared Obstacle Avoidance Sensor - IR Transmitting and Receiving Tube with Photoelectric Switch by Ron Thomas
Normally high performance
Seems to work well, but the performance is usually high and if there is an obstacle, the output will shut down. The Arduino has an input pull-up function, but no input pull-up, so a resistor to ground had to be used to change state. Not a big deal, but I think the output would be better if it were grounded when triggered.
- Decent performance
- Long delivery time
