The HC-020K Double Speed Measuring Sensor Module is an optical encoder sensor designed for precise speed and position measurement. It consists of an infrared transmitter and receiver that detect the movement of a slotted encoder disc to generate accurate pulse signals.
The module provides two TTL output channels (A and B), allowing both speed and rotation direction detection through quadrature encoding. With a maximum measurement frequency of 100kHz and a 20-line encoder disc, it delivers stable and reliable performance even at high rotational speeds.
Its compact design, low power consumption, and simple interface make it suitable for robotics, motor control, conveyor systems, educational projects, industrial automation, and embedded system development.
Features:
- High-precision optical speed measurement module
- Dual-channel A/B TTL output for quadrature encoding
- Supports speed and rotation direction detection
- 20-line encoder disc for accurate pulse generation
- High measurement frequency up to 100kHz
- Compatible with Arduino, Raspberry Pi, ESP32, STM32, and other MCUs
