IR Infrared Obstacle Avoidance Module Sensor Arduino Car Robot


  • When the module detects obstacles in front of the signal, the circuit board green indicator light level, while the OUT port continuous output low-level signals, the module detects a distance of 2 ~ 80cm, detection angle 35 °, the detection distance can be potential adjustment with adjustment potentiometer clockwise, the increase in detection distance; counterclockwise adjustment potentiometer, the detection distance decreased.
  • The sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The black minimum detection range, white maximum; small area object distance is small, a large area from the large.
  • The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO
  • 3-5V DC power supply module can be used. When the power is turned on, the red power LED is lit

IR Infrared Flame Detection Sensor Module

Module Features:

  • - Can detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighters distance of 80cm, the larger the flame, the greater the distance test
  • - The detection angle of 60 degrees, the flame spectrum particularly sensitive
  • - Sensitivity adjustable (shown in blue digital potentiometer adjustment)
  • - The comparator output signal clean waveform is good, driving ability, than 15mA
  • - With a precision potentiometer adjustable sensitivity adjustment
  • - Operating Voltage 3.3V-5V
  • - The output in the form: DO digital switching outputs (0 and 1) and AO analog voltage output
  • - A fixed bolt holes for easy installation
  • - Using a wide voltage LM393 comparator

Module for use:

  • - The flame sensor most sensitive to ordinary light is also a reaction, generally used as fire alarm and other purposes.
  • - A small panel output interface can be directly connected with the microcontroller IO port
  • - The sensor and the flame to maintain a certain distance, so as not to damage the sensor temperature of the test flame lighters distance 80cm, the larger the flame, the greater the distance test
  • - Small plates analog output mode and the AD conversion process, you can get higher accuracy
