Obstacle Avoidance Sensor, IR Infrared Obstacle Avoidance Sensor Module for Smart Robot, Car, Production Line, Black and White Line Tracking

• ★★★ 【Detail Instruction】 - When module detects obstacles ahead, the green indicator light on the circuit board is on and at the same time the OUT port outputs low level detection distance can be adjusted with potentiometer, clockwise to increase detection distance; counter-clockwise to reduce detection distance.
• ★★★ 【Detection Range】 - Active infrared reflection detecting sensor, so the target reflectivity and shape is the key of the detection range. Black color has the minimum detection range, white has the maximum; small objects have a short detection range, large objects have a long detection range.
• ★★★ 【Stable Performance】 - Sensor module output port OUT can be directly connected to micro-controller IO port, also can drive a 5V relay directly. Comparator uses the LM393 chips, can use 3 to 5V DC power supply.
• ★★★ 【Applicability】 - Designed with 3mm screw holes for convenient fixation and easy installation. The sensor module is adaptable to ambient light. It can be widely used for robot obstacle avoidance, obstacle avoidance car, assembly line, black and white line tracking and many other occasions.
• ★★★ 【Tips】 - The detection range of the sensor can be adjusted with potentiometer, effective distance range 2 ~ 60cm, little interference, easy assembly and use. Each module has already adjusted threshold compare voltage with potentiometer well, so please do not arbitrarily adjust potentiometer.

Description: The sensor module is adaptable to ambient light. It has a pair of infrared transmit and receive tubes. The transmit tube emits a certain frequency IR, which is reflected when obstacles (reflective surface) are detected and received by the receive tube. After processing with the comparator circuit glows green light and the signal output interface outputs a digital signal (a signal with low voltage level). Detection distance can be adjusted with the potentiometer, effective distance range 2 ~ 60cm, working voltage 3.3V to 5V. Product features: Comparator uses the LM393 chips, stable performance. Can use 3 to 5V DC power. When switched on, the red power indicator lights up. Designed with 3mm screw holes for convenient fixation and easy installation; Each module has already set the threshold reference voltage with the potentiometer, so do not arbitrarily set the potentiometer. Specifications: Working voltage: 3.3 ~ 5V Detection range: 2 ~ 30cm Detection angle: 35 ° Wiring: VCC-VCC; GND GND; OUT-IO Size: 4 * 1.5cm / 1.5 * 0.6in Quantity: 5 pieces Weight: 3g (approx.) Module interface: VCC: External connection of 3.3V-5V voltage (can be connected directly to 5V microcontroller and 3.3V microcontroller) GND: External GND OUT: Digital output port (0 and 1) Package contents: 5 x modules
