20 Pieces IR infrared obstacle avoidance sensor module 3-wire reflective photoelectric sensor module compatible with Arduino/Raspberry Pi 3/Smart Car Robot Feature: When the module detects an obstacle in front of the signal, the green indicator lights on the board level, while the OUT port sustained low signal output, the module detects the distance 2 - 30 cm, detection angle 35 degree, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases. Counterclockwise adjustment potentiometer, reducing detection distance. Infrared reflection detection: The sensor active infrared reflection detection, target reflectivity and therefore the shape is critical detection distance. Where the minimum detection distance black, white, maximum; small objects away from a small area, a large area from the grand. Connect to: The sensor module output port OUT port can be directly connected to the microcontroller can also be directly drive a 5V relay; Connection: vCC-VCC; GND-GND; OUT. Usage: Can be applied for 3-5V direct current power supply modules. When the power is turned on, the red power indicator light. Using the comparator LM393. Each module has been shipped threshold comparator voltage adjusted by potentiometer good, non-special case, do not adjustable potentiometer. Specification: Interface: 1. VCC: external 3.3-5 voltage (can be directly connected to 5v MCU and 3.3v MCU) 2. GND: gND external 3. OUT: small board digital output interfaces (0 and 1) Connection : vCC-VCC; GND-GND; OUT Board size: 3.1 x 1.5 cm/ 1.22 x 0.59 inch, with the screw holes of 3mm, easy fixed installation Package includes: 20 x Infrared obstacle avoidance module Note: The mention of brand names and any related models above are only for purposes of demonstrating compatibility, our trademark is Frienda.

Application: the IR sensor module can be applied for 3-5V DC power supply modules; There is a red power indicator. Easy to use: the output port OUT sensor module can be directly connected to the microcontroller port, you can directly drive a 5V relay. 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 adjustable. 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. 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 same time signal output interface to output digital signal (a low level signal).
