IR Tracking Sensor Module 4 Channel

From the shop's description

4-Channel IR Tracking Sensor Module – Line Following and Obstacle Avoidance Features: Four Independent Sensors: Equipped with four IR transmitter-receiver pairs for precise detection. ​ Adjustable Sensitivity: Onboard potentiometers allow tuning to various surface types and lighting conditions. ​ Digital Outputs: Provides TTL-level outputs compatible with microcontrollers like Arduino. ​ Compact Design: Small form factor facilitates easy integration into robotic platforms. ​ Visual Indicators: LEDs indicate sensor status, aiding in system monitoring and troubleshooting. Specification: Working voltage: 3.3V-5V DC Working current: as far as possible to choose 1A above power supply Working temperature: – 3 DEG C – less Mounting aperture: M3 screw Detection range: 1mm to 60 CM can be adjusted, the more close to the performance of the more stable, white reflection distance. Operating voltage: 3.3V-5V DC Main board: 43×39×11mm sensor modules: 23 × 12 × 12 mm Diameter of the fastening holes: 3m Output interface: 6 wire system interface (4 for 1234 signal output end, + for positive power supply, – for negative power is also the ground) Output signal: TTL level (can be directly connected to the microcontroller I/0, sensing the sensor back when the infrared light, red light, the output low level; no infrared light, the indicator is not bright, the output high level). Application: Intelligent vehicle or robot line (including black and white lines), along the black path, also called tracing. Smart car to avoid the cliff, fall. Smart car obstacle avoidance Package Includes: 1 x Tracking Module (Hollow Board + Small Plate Forward). 12 X Female to Female Dupont Lines (10 cm).
