Full Specification

  • IC : LM3935
  • Working voltage : 3-5 VDC (When power is turned on, red indicator lights.)
  • Detection distance : 2~30cm
  • Detection angle : 35’
  • Screw hole diameter : 3mm

When the module detects an obstacle in front of the signal, the circuit board green indicator lights. Adjusting the potentiometer clockwise, the detection distance increases; counter-clockwise adjustment potentiometer, detection distance decreases. The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay.
