IR Infrared Obstacle Avoidance Sensor Distance Detection Module for Arduino Smart Car Robot DIYmalls (Pack of 10)
Descripción
- This is IR infrared obstacle avoidance sensor module, and it can't measure length.
- You have to be very careful about dialing in the potentiometer to get it set to the desired range. A fraction of a degree turn may be all you need.
- The sensor module light is adaptable to the environmen. It has a pair of infrared transmitting and receiving tube, tube infrared emit a certain frequency, when detecting direction meet with 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).
- It can be through the potentiometer knob adjust the detection distance, effective distance range 2 ~ 30cm. Working voltage is 3.3V to 5V. It can be widely used in robot obstacle avoidance, obstacle avoidance car.
- If you have any problem, please contact seller as follow: click "DIYmaker"(you can find "Sold by DIYmaker" under Buy Now button), in the new page, click "Ask a question".
Specification: 1. when the module detects obstacles in front of the signal, the green indicator on the circuit board light level and at the same time the OUT port output low level signal, the detection module from 2 ~ 30cm, 35°detection Angle, test distance can be adjusted through the potentiometer, adjustable potentiometer clockwise, the detection distance increases; Counter-clockwise tuning potentiometer, detection distance is reduced. 2. sensors, active infrared reflection detection, therefore the reflectivity and shape of the target is the key of the detection range. White one black detection range, minimum maximum; Small area of the object distance, large distance. 3. the sensor module output port OUT can be directly connected to the microcontroller IO port can, also can drive a 5v relay directly; Connection mode: the VCC - VCC; GND - GND; The OUT - the IO 4. the comparator USES the LM393, working stability; 5. can be used for 3 to 5V DC power to power supply module. When power on, the red power indicator light lit; 6. 3 mm screw holes, easy fixed, installation; 7. circuit board size: 3.2cm*1.4cm 8. each module is shipped already compare threshold voltage through the potentiometer to adjust good, not special circumstances, please do not arbitrarily adjust the potentiometer. Interface: 1. VCC voltage is 3.3V to 5V converter (which can be directly connected to 5V single-chip microcontroller and 3.3V) 2. GND external GND 3. OUT of small plate digital output interface (0 and 1) Package Included: 10 X IR Infrared Obstacle Avoidance Sensor

good quality
very helpful adjustable distance sensing. which helps with projects considering you can adjust it in a project and real world scenario rather than programming the distance or trying to fiddle around with the actual distance of the Infrared LEDS which could be a hassle for that "sweet spot"
