Design with MKE-S10 CNY70 Line Follower Sensor in Cirkit DesignerThe MKE-S10 CNY70 is a compact line follower sensor designed for robotics and automation applications. It utilizes an infrared LED and a phototransistor to detect the contrast between a line (typically black) and the surrounding surface (typically white). This sensor is widely used in educational robots, maze solvers, and industrial line following vehicles.
This circuit is designed for a robotic system, featuring a Massive Sumo Board as the central controller. It integrates multiple FS-80NK diffuse IR sensors and IR line sensors for obstacle detection and line following, respectively, and controls two GM25 DC motors via MD13s motor drivers for movement. Power is supplied by an 11.1V LiPo battery.

This circuit features a MakerEdu Creator microcontroller board interfaced with two MKE-S11 IR Infrared Obstacle Avoidance Sensors, a MKE-M02 Push Button Tact Switch, a MKE-M15 Bluetooth module, and a MKE-M08 LCD2004 I2C display module. The push button is connected to a digital input for user interaction, while the IR sensors are likely used for detecting obstacles. The Bluetooth module enables wireless communication, and the LCD display provides a user interface for displaying information or statuses.

Q: Can the MKE-S10 CNY70 sensor detect colors other than black and white? A: The sensor is designed to detect reflectivity differences. While optimized for black and white, it can detect other colors if there is sufficient contrast.
Q: What is the maximum operating distance of the sensor? A: The sensor operates best within a range of 0.5mm to 15mm from the surface.
Q: How can I adjust the sensitivity of the sensor? A: Sensitivity can be adjusted by calibrating the threshold value in your code based on the analog voltage readings from the sensor.
Q: Is it possible to use multiple MKE-S10 CNY70 sensors on a single robot? A: Yes, you can use multiple sensors to improve line detection and navigation accuracy. Ensure each sensor is connected to a separate analog input pin on your microcontroller.
