The KY-022 module is ideally suited to infrared light detection within the range of 700nm -1mm, typically seen in project robots and remote control receivers. The data pin outputs HIGH when the sensor is triggered. Working at a low 3.3 – 5V input the module will output HIGH values on detecting a signal and LOW values while not detecting. A data LED is mounted onto the board that lights when the sensor is triggered. Features and Specifications:- Voltage : 3.3V to 5V Characteristics : 700nm – 1mm Chipset : TSOP1838 37.9kHz Daylight rejection : up to 500LUX Receiving distance : up to 18 m
