Feature: there is a pair of infrared transmitting and receiving tube of the IR sensor module, tube infrared emit a certain frequency, when the detection direction meets the obstacles (reflecting surface), reflected infrared receiving tube, after the comparator circuit processing, green indicator will light up, at the time signal output interface to output digital signal (a low level signal)Function: the IR infrared obstacle avoidance sensor module can be applied in robot obstacle avoidance, obstacle avoidance car, line count, black and white line tracking, etc.Adjustable distance: the detection distance of the infrared module is 2 to 30 cm, and the detection angle is 35 degrees, the distance The distance at which the potential can be detected is adjustableEasy to : the output port OUT sensor module can be directly connected to the microcontroller IO port, you can directly drive a 5V relayApplication: the IR sensor module can be applied for 3-5V DC supply modules; There is a red indicatorInfrared reflection detection:The sensor infrared reflection detection, reflectivity and therefore the shape is critical detection distance. Where the minimum detection distance black, white, maximum; small objects from a small area, a area from the . to:The sensor module output port OUT port can be directly connected to the microcontroller IO can also be directly drive a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO.Interface:1. VCC: external 3.3-5 voltage (can be directly connected to 5v MCU and 3.3v MCU)2. GND: GND external3. OUT: small board digital output interfaces (0 and 1)Connection: VCC-VCC; GND-GND; OUT-IOsize:3.2x1.4cmMaterial:ABScolour:Photo ColorPackage Contents:20 * Infrared obstacle avoidance moduleOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
