QUICK OVERVIEW Operating Voltage: 3.5V-5V Supply Current: 15mA Optimal Sensing Distance: 3mm Designed with the reflected infrared sensor, indicator light. Built in a potentiometer for sensitivity control. On-board LM393 voltage comparator chip and infrared sensing probe TCRT5000L Signal detection sensitivity can adjust Reserve all the way more circuits (P3 voltage drawn) Features : Designed with the reflected infrared sensor, indicator light. Built in a potentiometer for sensitivity control. On-board LM393 voltage comparator chip and infrared sensing probe TCRT5000L Onboard signal output instructions, the output is the highly effective signal at the same time, the indicator lamp light output signal can be directly and single-chip microcomputer IO connection & middot Signal detection sensitivity can adjust Reserve all the way more circuits (P3 voltage drawn) Using the TCRT5000 infrared reflection sensor Output form: digital switch output (0 and 1) A fixed bolt hole, convenient installation. Package Includes : 1 x For Arduino Smart Car TCRT5000 Obstacle Avoidance Infrared Track Sensor Module.
