This sensor sends an infrared light, which is reflected when it hits an obstacle and received by the photodiode. The sensitivity of the receiver as well as the strength of the transmitter can be set. This allows you to set the distance at which the sensor is triggered. This is done with two different potentiometers. The sensor can be used to control autonomous robots, among other things. https://elecena.pl/product/28015652/joy-it-infrared-proximity-sensor 2025-03-12 https://elecena.pl/product/28015652/joy-it-infrared-proximity-sensor 2025-07-18 https://elecena.pl/product/28015652/joy-it-infrared-proximity-sensor 2025-08-07 https://elecena.pl/product/28015652/joy-it-infrared-proximity-sensor 2025-09-17
