Sensor infrarojo, se peude utilizar como controlador de fin de carrera y como sensor para medir RPM
Main chip:LM393,Correlation type infrared head
Working voltage:DC 5V
- Signal output indication
- Sigle-way signal output
- Output effective signal is low level
- Sensitivity non-adjustable
- Can be used to Workpiece count and Motor speed detect
- Circuit board outputs switch quantity
- The OUT pin is low leve when there is no object between the photoelectric sensor,and the red LED is lit.
- The OUT pin is high leve when there is a object between the photoelectric sensor,and the green LED is not bright.
- The OUT port can be connected to MCU directly,Than MCU can calculate how mang circle the smaller car have runned per unit time.
