Photo Reflective Sensor Module (CNY70)

The Photo Reflective Sensor Module (CNY70) is built around the CNY70, a reflective optical sensor that combines an infrared LED and a phototransistor in one package. It senses the light reflected from a surface a few millimetres away, which makes it a favourite for line-following robots, encoders and edge detection.

Photo Reflective Sensor Module (CNY70) – Key Features

• CNY70 reflective IR sensor
• Infrared LED and phototransistor in one package
• Very short sensing distance (a few millimetres)
• Analog and/or digital output depending on the board
• Mounting holes for robots and fixtures

Applications

Makers, students and technicians use it in many kinds of projects, for example:

• Line-following robots
• Black and white mark detection
• Rotary encoders and RPM counting
• Paper and object presence detection
• Educational robotics

Usage Tips

Mount the sensor close to the surface, ideally around 0.5–5mm, and shield it from strong sunlight. If the module has a potentiometer, adjust it to set the black/white threshold.
