yyuezhi 10pcs Infrared Module Sensor Infrared Sensor Module Obstacle Avoidance IR Infrared Obstacle Avoidance Sensor Module Infrared Reflective Photoelectric Switch IR Barrier Line Track Sensor Blue

Description

The sensor module is highly adaptable to ambient light and has a pair of infrared transmit and receive tubes. The transmitting tube emits infrared rays of a certain frequency. When the detection direction encounters an obstacle (reflecting surface), the infrared rays are reflected and received by the receiving tube. After the comparator circuit has been processed, the green indicator light will illuminate and the signal output interface will output a digital signal (a low level signal). Specification: Color: blue Board size: 32mmx14mm (1.26x0.55inch) Working voltage: 3.3V ~ 5V Detection distance: 2 ~ 30cm Detection angle: 35 ° With 3mm screw holes for easy attachment and installation Features: Low interference, easy installation and convenient to use. Application: Widely used in robots to avoid obstacles, obstacle avoidance cars, production line counting and black and white line tracking, etc. Delivery: 10 x IR Infrared Obstacle Avoidance Sensor Module Interface Description (3-wire): 1. VCC: external 3.3V-5V 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) Module Parameter Description: The sensor actively detects infrared reflections so that the reflectivity and shape of the target are the key to detecting the distance. Among these, the black detection distance is the smallest and white is the largest, the small area object is at a small distance, and the large area distance is large.
